By +convention, it is the English version of the message, with non-ASCII +characters replaced by ASCII approximations. This choice allows the +translators to work with message catalogs, called PO files, that contain +both the English and the translated versions of each message, and can be +installed using the \fBmsgfmt\fP utility. +.PP +A message domain is a set of translatable \fImsgid\fP messages. Usually, +every software package has its own message domain. The domain name is used +to determine the message catalog where the translation is looked up; it must +be a non-empty string. For the \fBgettext\fP function, it is specified through +a preceding \fBtextdomain\fP call. For the \fBdgettext\fP and \fBdcgettext\fP +functions, it is passed as the \fIdomainname\fP argument; if this argument is +NULL, the domain name specified through a preceding \fBtextdomain\fP call is +used instead. +.PP +Translation lookup operates in the context of the current locale. For the +\fBgettext\fP and \fBdgettext\fP functions, the \fBLC_MESSAGES\fP locale +facet is used. It is determined by a preceding call to the \fBsetlocale\fP +function. \fBsetlocale (LC_ALL, "")\fP initializes the \fBLC_MESSAGES\fP locale +based on the first nonempty value of the three environment variables +\fBLC_ALL\fP, \fBLC_MESSAGES\fP, \fBLANG\fP; see \fBsetlocale\fP(3). For the +\fBdcgettext\fP function, the locale facet is determined by the \fIcategory\fP +argument, which should be one of the \fBLC_xxx\fP constants defined in the + header, excluding \fBLC_ALL\fP. In both cases, the functions also +use the \fBLC_CTYPE\fP locale facet in order to convert the translated message +from the translator's codeset to the current locale's codeset, unless +overridden by a prior call to the \fBbind_textdomain_codeset\fP function. +.PP +The message catalog used by the functions is at the pathname +\fIdirname\fP/\fIlocale\fP/\fIcategory\fP/\fIdomainname\fP.mo. Here +\fIdirname\fP is the directory specified through \fBbindtextdomain\fP. Its +default is system and configuration dependent; typically it is +\fIprefix\fP/share/locale, where \fIprefix\fP is the installation prefix of the +package. \fIlocale\fP is the name of the current locale facet; the GNU +implementation also tries generalizations, such as the language name without +the territory name. \fIcategory\fP is \fBLC_MESSAGES\fP for the \fBgettext\fP +and \fBdgettext\fP functions, or the argument passed to the \fBdcgettext\fP +function. +.PP +If the \fBLANGUAGE\fP environment variable is set to a nonempty value, and the +locale is not the "C" locale, the value of \fBLANGUAGE\fP is assumed to contain +a colon separated list of locale names. The functions will attempt to look up +a translation of \fImsgid\fP in each of the locales in turn.

This means you can hook h11 up to your favorite network +API, and that could be anything you want: synchronous, threaded, +asynchronous, or your own implementation of `RFC 6214 +`_ -- h11 won't judge you. +(Compare this to the current state of the art, where every time a `new +network API `_ comes along then someone +gets to start over reimplementing the entire HTTP protocol from +scratch.) Cory Benfield made an `excellent blog post describing the +benefits of this approach +`_, or if you like video +then here's his `PyCon 2016 talk on the same theme +`_. + +This also means that h11 is not immediately useful out of the box: +it's a toolkit for building programs that speak HTTP, not something +that could directly replace ``requests`` or ``twisted.web`` or +whatever. But h11 makes it much easier to implement something like +``requests`` or ``twisted.web``. + +At a high level, working with h11 goes like this: + +1) First, create an ``h11.Connection`` object to track the state of a + single HTTP/1.1 connection. + +2) When you read data off the network, pass it to + ``conn.receive_data(...)``; you'll get back a list of objects + representing high-level HTTP "events". + +3) When you want to send a high-level HTTP event, create the + corresponding "event" object and pass it to ``conn.send(...)``; + this will give you back some bytes that you can then push out + through the network. + +For example, a client might instantiate and then send a +``h11.Request`` object, then zero or more ``h11.Data`` objects for the +request body (e.g., if this is a POST), and then a +``h11.EndOfMessage`` to indicate the end of the message. Then the +server would then send back a ``h11.Response``, some ``h11.Data``, and +its own ``h11.EndOfMessage``. If either side violates the protocol, +you'll get a ``h11.ProtocolError`` exception. + +h11 is suitable for implementing both servers and clients, and has a +pleasantly symmetric API: the events you send as a client are exactly +the ones that you receive as a server and vice-versa. + +`Here's an example of a tiny HTTP client +`_ + +It also has `a fine manual `_. + +FAQ +--- + +*Whyyyyy?* + +I wanted to play with HTTP in `Curio +`__ and `Trio +`__, which at the time didn't have any +HTTP libraries. So I thought, no big deal, Python has, like, a dozen +different implementations of HTTP, surely I can find one that's +reusable. I didn't find one, but I did find Cory's call-to-arms +blog-post. So I figured, well, fine, if I have to implement HTTP from +scratch, at least I can make sure no-one *else* has to ever again. + +*Should I use it?* + +Maybe. You should be aware that it's a very young project. But, it's +feature complete and has an exhaustive test-suite and complete docs, +so the next step is for people to try using it and see how it goes +:-). If you do then please let us know -- if nothing else we'll want +to talk to you before making any incompatible changes! + +*What are the features/limitations?* + +Roughly speaking, it's trying to be a robust, complete, and non-hacky +implementation of the first "chapter" of the HTTP/1.1 spec: `RFC 7230: +HTTP/1.1 Message Syntax and Routing +`_. That is, it mostly focuses on +implementing HTTP at the level of taking bytes on and off the wire, +and the headers related to that, and tries to be anal about spec +conformance. It doesn't know about higher-level concerns like URL +routing, conditional GETs, cross-origin cookie policies, or content +negotiation. But it does know how to take care of framing, +cross-version differences in keep-alive handling, and the "obsolete +line folding" rule, so you can focus your energies on the hard / +interesting parts for your application, and it tries to support the +full specification in the sense that any useful HTTP/1.1 conformant +application should be able to use h11. + +It's pure Python, and has no dependencies outside of the standard +library. + +It has a test suite with 100.0% coverage for both statements and +branches. + +Currently it supports Python 3 (testing on 3.8-3.12) and PyPy 3. +The last Python 2-compatible version was h11 0.11.x. +(Originally it had a Cython wrapper for `http-parser +`_ and a beautiful nested state +machine implemented with ``yield from`` to postprocess the output. But +I had to take these out -- the new *parser* needs fewer lines-of-code +than the old *parser wrapper*, is written in pure Python, uses no +exotic language syntax, and has more features. It's sad, really; that +old state machine was really slick. I just need a few sentences here +to mourn that.) + +I don't know how fast it is. I haven't benchmarked or profiled it yet, +so it's probably got a few pointless hot spots, and I've been trying +to err on the side of simplicity and robustness instead of +micro-optimization. But at the architectural level I tried hard to +avoid fundamentally bad decisions, e.g., I believe that all the +parsing algorithms remain linear-time even in the face of pathological +input like slowloris, and there are no byte-by-byte loops. (I also +believe that it maintains bounded memory usage in the face of +arbitrary/pathological input.) + +The whole library is ~800 lines-of-code. You can read and understand +the whole thing in less than an hour. Most of the energy invested in +this so far has been spent on trying to keep things simple by +minimizing special-cases and ad hoc state manipulation; even though it +is now quite small and simple, I'm still annoyed that I haven't +figured out how to make it even smaller and simpler. (Unfortunately, +HTTP does not lend itself to simplicity.) + +The API is ~feature complete and I don't expect the general outlines +to change much, but you can't judge an API's ergonomics until you +actually document and use it, so I'd expect some changes in the +details. + +*How do I try it?* + +.. code-block:: sh + + $ pip install h11 + $ git clone git@github.com:python-hyper/h11 + $ cd

The last +# two are stored implicitly in the pending_switch_proposals set as: +# (state of 4) == (_SWITCH_CONNECT in pending_switch_proposals) +# (state of 5) == (_SWITCH_UPGRADE in pending_switch_proposals) +# +# And each of these machines has two different kinds of transitions: +# +# a) Event-triggered +# b) State-triggered +# +# Event triggered is the obvious thing that you'd think it is: some event +# happens, and if it's the right event at the right time then a transition +# happens. But there are somewhat complicated rules for which machines can +# "see" which events. (As a rule of thumb, if a machine "sees" an event, this +# means two things: the event can affect the machine, and if the machine is +# not in a state where it expects that event then it's an error.) These rules +# are: +# +# 1) The client machine sees all h11.events objects emitted by the client. +# +# 2) The server machine sees all h11.events objects emitted by the server. +# +# It also sees the client's Request event. +# +# And sometimes, server events are annotated with a _SWITCH_* event. For +# example, we can have a (Response, _SWITCH_CONNECT) event, which is +# different from a regular Response event. +# +# 3) The keep-alive machine sees the process_keep_alive_disabled() event +# (which is derived from Request/Response events), and this event +# transitions it from True -> False, or from False -> False. There's no way +# to transition back. +# +# 4&5) The _SWITCH_* machines transition from False->True when we get a +# Request that proposes the relevant type of switch (via +# process_client_switch_proposals), and they go from True->False when we +# get a Response that has no _SWITCH_* annotation. +# +# So that's event-triggered transitions. +# +# State-triggered transitions are less standard. What they do here is couple +# the machines together. The way this works is, when certain *joint* +# configurations of states are achieved, then we automatically transition to a +# new *joint* state. So, for example, if we're ever in a joint state with +# +# client: DONE +# keep-alive: False +# +# then the client state immediately transitions to: +# +# client: MUST_CLOSE +# +# This is fundamentally different from an event-based transition, because it +# doesn't matter how we arrived at the {client: DONE, keep-alive: False} state +# -- maybe the client transitioned SEND_BODY -> DONE, or keep-alive +# transitioned True -> False. Either way, once this precondition is satisfied, +# this transition is immediately triggered. +# +# What if two conflicting state-based transitions get enabled at the same +# time? In practice there's only one case where this arises (client DONE -> +# MIGHT_SWITCH_PROTOCOL versus DONE -> MUST_CLOSE), and we resolve it by +# explicitly prioritizing the DONE -> MIGHT_SWITCH_PROTOCOL transition. +# +# Implementation +# -------------- +# +# The event-triggered transitions for the server and client machines are all +# stored explicitly in a table. Ditto for the state-triggered transitions that +# involve just the server and client state. +# +# The transitions for the other machines, and the state-triggered transitions +# that involve the other machines, are written out as explicit Python code. +# +# It'd be nice if there were some cleaner way to do all this.

Sending HTTP requests. + +It does not provide any high level model abstractions over the API, +does not handle redirects, multipart uploads, building authentication headers, +transparent HTTP caching, URL parsing, session cookie handling, +content or charset decoding, handling JSON, environment based configuration +defaults, or any of that Jazz. + +Some things HTTP Core does do: + +* Sending HTTP requests. +* Thread-safe / task-safe connection pooling. +* HTTP(S) proxy & SOCKS proxy support. +* Supports HTTP/1.1 and HTTP/2. +* Provides both sync and async interfaces. +* Async backend support for `asyncio` and `trio`. + +## Requirements + +Python 3.8+ + +## Installation + +For HTTP/1.1 only support, install with: + +```shell +$ pip install httpcore +``` + +There are also a number of optional extras available... + +```shell +$ pip install httpcore['asyncio,trio,http2,socks'] +``` + +## Sending requests + +Send an HTTP request: + +```python +import httpcore + +response = httpcore.request("GET", "https://www.example.com/") + +print(response) +# +print(response.status) +# 200 +print(response.headers) +# [(b'Accept-Ranges', b'bytes'), (b'Age', b'557328'), (b'Cache-Control', b'max-age=604800'), ...] +print(response.content) +# b'\n\n\nExample Domain\n\n\n ...' +``` + +The top-level `httpcore.request()` function is provided for convenience. In practice whenever you're working with `httpcore` you'll want to use the connection pooling functionality that it provides. + +```python +import httpcore + +http = httpcore.ConnectionPool() +response = http.request("GET", "https://www.example.com/") +``` + +Once you're ready to get going, [head over to the documentation](https://www.encode.io/httpcore/). + +## Motivation + +You *probably* don't want to be using HTTP Core directly. It might make sense if +you're writing something like a proxy service in Python, and you just want +something at the lowest possible level, but more typically you'll want to use +a higher level client library, such as `httpx`. + +The motivation for `httpcore` is: + +* To provide a reusable low-level client library, that other packages can then build on top of. +* To provide a *really clear interface split* between the networking code and client logic, + so that each is easier to understand and reason about in isolation. + +## Dependencies + +The `httpcore` package has the following dependencies... + +* `h11` +* `certifi` + +And the following optional extras... + +* `anyio` - Required by `pip install httpcore['asyncio']`. +* `trio` - Required by `pip install httpcore['trio']`. +* `h2` - Required by `pip install httpcore['http2']`. +* `socksio` - Required by `pip install httpcore['socks']`. + +## Versioning + +We use [SEMVER for our versioning policy](https://semver.org/). + +For changes between package versions please see our [project changelog](CHANGELOG.md). + +We recommend pinning your requirements either the most current major version, or a more specific version range: + +```python +pip install 'httpcore==1.*' +``` +# Changelog + +All notable changes to this project will be documented in this file. + +The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/). + +## Version 1.0.9 (April 24th, 2025) + +- Resolve https://github.com/advisories/GHSA-vqfr-h8mv-ghfj with h11 dependency update. (#1008) + +## Version 1.0.8 (April 11th, 2025) + +- Fix `AttributeError` when importing on Python 3.14. (#1005) + +## Version 1.0.7 (November 15th, 2024) + +- Support `proxy=…` configuration on `ConnectionPool()`. (#974) + +## Version 1.0.6 (October 1st, 2024) + +- Relax `trio` dependency pinning. (#956) +- Handle `trio` raising `NotImplementedError` on unsupported platforms. (#955) +- Handle mapping `ssl.SSLError` to `httpcore.ConnectError`. (#918) + +## 1.0.5 (March 27th, 2024) + +- Handle `EndOfStream` exception for anyio backend. (#899) +- Allow trio `0.25.*` series in package dependancies. (#903) + +## 1.0.4 (February 21st, 2024) + +- Add `target` request extension. (#888) +- Fix support for connection `Upgrade` and `CONNECT` when some data in the stream has been read. (#882) + +## 1.0.3 (February 13th, 2024) + +- Fix support for async cancellations. (#880) +- Fix trace extension when used with socks proxy. (#849) +- Fix SSL context for connections using the "wss" scheme (#869) + +## 1.0.2 (November 10th, 2023) + +- Fix `float("inf")` timeouts in `Event.wait` function. (#846) + +## 1.0.1 (November 3rd, 2023) + +- Fix pool timeout to account for the total time spent retrying. (#823) +- Raise a neater RuntimeError when the correct async deps are not installed. (#826) +- Add support for synchronous TLS-in-TLS streams. (#840) + +## 1.0.0 (October 6th, 2023) + +From version 1.0 our async support is now optional, as the package has minimal dependencies by default. + +For async support use either `pip install 'httpcore[asyncio]'` or `pip install 'httpcore[trio]'`. + +The project versioning policy is now explicitly governed by SEMVER.

This extension is needed for the HTTPX cli, in order to... + +* Log the point at which the connection is established, and the IP/port on which it is made. +* Determine if the outgoing request should log as HTTP/1.1 or HTTP/2, rather than having to assume it's HTTP/2 if the --http2 flag was passed. (Which may not actually be true.) +* Log SSL version info / certificate info. + +Note that `curio` support is not currently available in 0.14.0.

(Pull #310) + +## 0.13.0 (April 21st, 2021) + +The 0.13 release updates the core API in order to match the HTTPX Transport API, +introduced in HTTPX 0.18 onwards. + +An example of making requests with the new interface is: + +```python +with httpcore.SyncConnectionPool() as http: + status_code, headers, stream, extensions = http.handle_request( + method=b'GET', + url=(b'https', b'example.org', 443, b'/'), + headers=[(b'host', b'example.org'), (b'user-agent', b'httpcore')] + stream=httpcore.ByteStream(b''), + extensions={} + ) + body = stream.read() + print(status_code, body) +``` + +### Changed + +- The `.request()` method is now `handle_request()`. (Pull #296) +- The `.arequest()` method is now `.handle_async_request()`. (Pull #296) +- The `headers` argument is no longer optional. (Pull #296) +- The `stream` argument is no longer optional. (Pull #296) +- The `ext` argument is now named `extensions`, and is no longer optional. (Pull #296) +- The `"reason"` extension keyword is now named `"reason_phrase"`. (Pull #296) +- The `"reason_phrase"` and `"http_version"` extensions now use byte strings for their values. (Pull #296) +- The `httpcore.PlainByteStream()` class becomes `httpcore.ByteStream()`. (Pull #296) + +### Added + +- Streams now support a `.read()` interface. (Pull #296) + +### Fixed + +- Task cancellation no longer leaks connections from the connection pool. (Pull #305) + +## 0.12.3 (December 7th, 2020) + +### Fixed + +- Abort SSL connections on close rather than waiting for remote EOF when using `asyncio`. (Pull #167) +- Fix exception raised in case of connect timeouts when using the `anyio` backend. (Pull #236) +- Fix `Host` header precedence for `:authority` in HTTP/2.

Timeout dictionary. +* response: `http_version` - Optional. Include the HTTP version used on the response. +* response: `reason` - Optional. Include the reason phrase used on the response. Only valid with HTTP/1.*. + +See https://github.com/encode/httpx/issues/1274#issuecomment-694884553 for the history behind this. + +Secondly, the async version of `request` is now namespaced as `arequest`. + +This allows concrete transports to support both sync and async implementations on the same class. + +### Added + +- Add curio support. (Pull #168) +- Add anyio support, with `backend="anyio"`. (Pull #169) + +### Changed + +- Update the Transport API to use 'ext' for optional extensions. (Pull #190) +- Update the Transport API to use `.request` and `.arequest` so implementations can support both sync and async. (Pull #189) + +## 0.10.2 (August 20th, 2020) + +### Added + +- Added Unix Domain Socket support. (Pull #139) + +### Fixed + +- Always include the port on proxy CONNECT requests.

(Pull #164) + +## 0.10.1 (August 7th, 2020) + +- Include `max_keepalive_connections` on `AsyncHTTPProxy`/`SyncHTTPProxy` classes. + +## 0.10.0 (August 7th, 2020) + +The most notable change in the 0.10.0 release is that HTTP/2 support is now fully optional. + +Use either `pip install httpcore` for HTTP/1.1 support only, or `pip install httpcore[http2]` for HTTP/1.1 and HTTP/2 support. + +### Added + +- HTTP/2 support becomes optional. (Pull #121, #130) +- Add `local_address=...` support. (Pull #100, #134) +- Add `PlainByteStream`, `IteratorByteStream`, `AsyncIteratorByteStream`. The `AsyncByteSteam` and `SyncByteStream` classes are now pure interface classes. (#133) +- Add `LocalProtocolError`, `RemoteProtocolError` exceptions. (Pull #129) +- Add `UnsupportedProtocol` exception. (Pull #128) +- Add `.get_connection_info()` method. (Pull #102, #137) +- Add better TRACE logs. (Pull #101) + +### Changed + +- `max_keepalive` is deprecated in favour of `max_keepalive_connections`. (Pull #140) + +### Fixed + +- Improve handling of server disconnects. (Pull #112) + +## 0.9.1 (May 27th, 2020) + +### Fixed + +- Proper host resolution for sync case, including IPv6 support. (Pull #97) +- Close outstanding connections when connection pool is closed. (Pull #98) + +## 0.9.0 (May 21th, 2020) + +### Changed + +- URL port becomes an `Optional[int]` instead of `int`. (Pull #92) + +### Fixed + +- Honor HTTP/2 max concurrent streams settings. (Pull #89, #90) +- Remove incorrect debug log. (Pull #83) + +## 0.8.4 (May 11th, 2020) + +### Added + +- Logging via HTTPCORE_LOG_LEVEL and HTTPX_LOG_LEVEL environment variables +and TRACE level logging. (Pull #79) + +### Fixed + +- Reuse of connections on HTTP/2 in close concurrency situations. (Pull #81) + +## 0.8.3 (May 6rd, 2020) + +### Fixed + +- Include `Host` and `Accept` headers on proxy "CONNECT" requests. +- De-duplicate any headers also contained in proxy_headers. +- HTTP/2 flag not being passed down to proxy connections. + +## 0.8.2 (May 3rd, 2020) + +### Fixed + +- Fix connections using proxy forwarding requests not being added to the +connection pool properly. (Pull #70) + +## 0.8.1 (April 30th, 2020) + +### Changed + +- Allow inherintance of both `httpcore.AsyncByteStream`, `httpcore.SyncByteStream` without type conflicts. + +## 0.8.0 (April 30th, 2020) +

HTTPX - A next-generation HTTP client for Python.

+ +

+ + Test Suite + + + Package version + +

+ +HTTPX is a fully featured HTTP client library for Python 3. It includes **an integrated command line client**, has support for both **HTTP/1.1 and HTTP/2**, and provides both **sync and async APIs**. + +--- + +Install HTTPX using pip: + +```shell +$ pip install httpx +``` + +Now, let's get started: + +```pycon +>>> import httpx +>>> r = httpx.get('https://www.example.org/') +>>> r + +>>> r.status_code +200 +>>> r.headers['content-type'] +'text/html; charset=UTF-8' +>>> r.text +'\n\n\nExample Domain...' +``` + +Or, using the command-line client. + +```shell +$ pip install 'httpx[cli]' # The command line client is an optional dependency. +``` + +Which now allows us to use HTTPX directly from the command-line... + +

+ httpx --help +

+ +Sending a request... + +

+ httpx http://httpbin.org/json +

+ +## Features + +HTTPX builds on the well-established usability of `requests`, and gives you: + +* A broadly [requests-compatible API](https://www.python-httpx.org/compatibility/). +* An integrated command-line client. +* HTTP/1.1 [and HTTP/2 support](https://www.python-httpx.org/http2/). +* Standard synchronous interface, but with [async support if you need it](https://www.python-httpx.org/async/). +* Ability to make requests directly to [WSGI applications](https://www.python-httpx.org/advanced/transports/#wsgi-transport) or [ASGI applications](https://www.python-httpx.org/advanced/transports/#asgi-transport). +* Strict timeouts everywhere. +* Fully type annotated. +* 100% test coverage. + +Plus all the standard features of `requests`... + +* International Domains and URLs +* Keep-Alive & Connection Pooling +* Sessions with Cookie Persistence +* Browser-style SSL Verification +* Basic/Digest Authentication +* Elegant Key/Value Cookies +* Automatic Decompression +* Automatic Content Decoding +* Unicode Response Bodies +* Multipart File Uploads +* HTTP(S) Proxy Support +* Connection Timeouts +* Streaming Downloads +* .netrc Support +* Chunked Requests + +## Installation + +Install with pip: + +```shell +$ pip install httpx +``` + +Or, to include the optional HTTP/2 support, use: + +```shell +$ pip install httpx[http2] +``` + +HTTPX requires Python 3.8+. + +## Documentation + +Project documentation is available at [https://www.python-httpx.org/](https://www.python-httpx.org/). + +For a run-through of all the basics, head over to the [QuickStart](https://www.python-httpx.org/quickstart/). + +For more advanced topics, see the [Advanced Usage](https://www.python-httpx.org/advanced/) section, the [async support](https://www.python-httpx.org/async/) section, or the [HTTP/2](https://www.python-httpx.org/http2/) section. + +The [Developer Interface](https://www.python-httpx.org/api/) provides a comprehensive API reference. + +To find out about tools that integrate with HTTPX, see [Third Party Packages](https://www.python-httpx.org/third_party_packages/). + +## Contribute + +If you want to contribute with HTTPX check out the [Contributing Guide](https://www.python-httpx.org/contributing/) to learn how to start. + +## Dependencies + +The HTTPX project relies on these excellent libraries: + +* `httpcore` - The underlying transport implementation for `httpx`. + * `h11` - HTTP/1.1 support. +* `certifi` - SSL certificates. +* `idna` - Internationalized domain name support. +* `sniffio` - Async library autodetection. + +As well as these optional installs: + +* `h2` - HTTP/2 support. *(Optional, with `httpx[http2]`)* +* `socksio` - SOCKS proxy support. *(Optional, with `httpx[socks]`)* +* `rich` - Rich terminal support. *(Optional, with `httpx[cli]`)* +* `click` - Command line client support. *(Optional, with `httpx[cli]`)* +* `brotli` or `brotlicffi` - Decoding for "brotli" compressed responses. *(Optional, with `httpx[brotli]`)* +* `zstandard` - Decoding for "zstd" compressed responses. *(Optional, with `httpx[zstd]`)* + +A huge amount of credit is due to `requests` for the API layout that +much of this work follows, as well as to `urllib3` for plenty of design +inspiration around the lower-level networking details. + +--- + +

HTTPX is BSD licensed code.
Designed & crafted with care.

+ *     Addison

+ *  B

+ *  ...
+ *
+ * + * The class can generate a list of labels for use as a UI "index", that is, a list of + * clickable characters (or character sequences) that allow the user to see a segment + * (bucket) of a larger "target" list. That is, each label corresponds to a bucket in + * the target list, where everything in the bucket is greater than or equal to the character + * (according to the locale's collation). Strings can be added to the index; + * they will be in sorted order in the right bucket. + *

+ * The class also supports having buckets for strings before the first (underflow), + * after the last (overflow), and between scripts (inflow). For example, if the index + * is constructed with labels for Russian and English, Greek characters would fall + * into an inflow bucket between the other two scripts. + *

+ * The AlphabeticIndex class is not intended for public subclassing. + * + *

Note: If you expect to have a lot of ASCII or Latin characters + * as well as characters from the user's language, + * then it is a good idea to call addLabels(Locale::getEnglish(), status).

+ * + *

Direct Use

+ *

The following shows an example of building an index directly. + * The "show..." methods below are just to illustrate usage. + * + * 

+ * // Create a simple index.  "Item" is assumed to be an application
+ * // defined type that the application's UI and other processing knows about,
+ * //  and that has a name.
+ *
+ * UErrorCode status = U_ZERO_ERROR;
+ * AlphabeticIndex index = new AlphabeticIndex(desiredLocale, status);
+ * index->addLabels(additionalLocale, status);
+ * for (Item *item in some source of Items ) {
+ *     index->addRecord(item->name(), item, status);
+ * }
+ * ...
+ * // Show index at top. We could skip or gray out empty buckets
+ *
+ * while (index->nextBucket(status)) {
+ *     if (showAll || index->getBucketRecordCount() != 0) {
+ *         showLabelAtTop(UI, index->getBucketLabel());
+ *     }
+ * }
+ *  ...
+ * // Show the buckets with their contents, skipping empty buckets
+ *
+ * index->resetBucketIterator(status);
+ * while (index->nextBucket(status)) {
+ *    if (index->getBucketRecordCount() != 0) {
+ *        showLabelInList(UI, index->getBucketLabel());
+ *        while (index->nextRecord(status)) {
+ *            showIndexedItem(UI, static_cast(index->getRecordData()))
+ *
+ * + * The caller can build different UIs using this class. + * For example, an index character could be omitted or grayed-out + * if its bucket is empty. Small buckets could also be combined based on size, such as: + * + * 
+ * ... A-F G-N O-Z ...
+ *
+ * + *

Client Support

+ *

Callers can also use the AlphabeticIndex::ImmutableIndex, or the AlphabeticIndex itself, + * to support sorting on a client that doesn't support AlphabeticIndex functionality. + * + *

The ImmutableIndex is both immutable and thread-safe. + * The corresponding AlphabeticIndex methods are not thread-safe because + * they "lazily" build the index buckets. + *

    + *
  • ImmutableIndex.getBucket(index) provides random access to all + * buckets and their labels and label types. + *
  • The AlphabeticIndex bucket iterator or ImmutableIndex.getBucket(0..getBucketCount-1) + * can be used to get a list of the labels, + * such as "...", "A", "B",..., and send that list to the client. + *
  • When the client has a new name, it sends that name to the server. + * The server needs to call the following methods, + * and communicate the bucketIndex and collationKey back to the client. + * + * 
    + * int32_t bucketIndex = index.getBucketIndex(name, status);
+ * const UnicodeString &label = immutableIndex.getBucket(bucketIndex)->getLabel();  // optional
+ * int32_t skLength = collator.getSortKey(name, sk, skCapacity);
+ *
    + * + *
  • The client would put the name (and associated information) into its bucket for bucketIndex. The sort key sk is a + * sequence of bytes that can be compared with a binary compare, and produce the right localized result.

+ * Line boundary analysis determines where a text string can be broken + * when line-wrapping. The mechanism correctly handles punctuation and + * hyphenated words. + *

+ * Sentence boundary analysis allows selection with correct + * interpretation of periods within numbers and abbreviations, and + * trailing punctuation marks such as quotation marks and parentheses. + *

+ * Word boundary analysis is used by search and replace functions, as + * well as within text editing applications that allow the user to + * select words with a double click.

See UDate + * for information about the `UDate` class.) + * + * Subclasses of `Calendar` interpret a `UDate` + * according to the rules of a specific calendar system. + * The most commonly used subclass of `Calendar` is + * `GregorianCalendar`. Other subclasses could represent + * the various types of lunar calendars in use in many parts of the world. + * + * **NOTE**: (ICU 2.6) The subclass interface should be considered unstable - + * it WILL change. + * + * Like other locale-sensitive classes, `Calendar` provides a + * static method, `createInstance`, for getting a generally useful + * object of this type. `Calendar`'s `createInstance` method + * returns the appropriate `Calendar` subclass whose + * time fields have been initialized with the current date and time: + * + * Calendar *rightNow = Calendar::createInstance(errCode); + * + * A `Calendar` object can produce all the time field values + * needed to implement the date-time formatting for a particular language + * and calendar style (for example, Japanese-Gregorian, Japanese-Traditional). + * + * When computing a `UDate` from time fields, some special circumstances + * may arise: there may be insufficient information to compute the + * `UDate` (such as only year and month but no day in the month), + * there may be inconsistent information (such as "Tuesday, July 15, 1996" + * -- July 15, 1996 is actually a Monday), or the input time might be ambiguous + * because of time zone transition. + * + * **Insufficient information.** The calendar will use default + * information to specify the missing fields. This may vary by calendar; for + * the Gregorian calendar, the default for a field is the same as that of the + * start of the epoch: i.e., YEAR = 1970, MONTH = JANUARY, DATE = 1, etc. + * + * **Inconsistent information.** If fields conflict, the calendar + * will give preference to fields set more recently. For example, when + * determining the day, the calendar will look for one of the following + * combinations of fields. The most recent combination, as determined by the + * most recently set single field, will be used. + * + * MONTH + DAY_OF_MONTH + * MONTH + WEEK_OF_MONTH + DAY_OF_WEEK + * MONTH + DAY_OF_WEEK_IN_MONTH + DAY_OF_WEEK + * DAY_OF_YEAR + * DAY_OF_WEEK + WEEK_OF_YEAR + * + * For the time of day: + * + * HOUR_OF_DAY + * AM_PM + HOUR + * + * **Ambiguous Wall Clock Time.** When time offset from UTC has + * changed, it produces an ambiguous time slot around the transition. For example, + * many US locations observe daylight saving time. On the date switching to daylight + * saving time in US, wall clock time jumps from 12:59 AM (standard) to 2:00 AM + * (daylight). Therefore, wall clock time from 1:00 AM to 1:59 AM do not exist on + * the date. When the input wall time fall into this missing time slot, the ICU + * Calendar resolves the time using the UTC offset before the transition by default. + * In this example, 1:30 AM is interpreted as 1:30 AM standard time (non-exist), + * so the final result will be 2:30 AM daylight time. + * + * On the date switching back to standard time, wall clock time is moved back one + * hour at 2:00 AM. So wall clock time from 1:00 AM to 1:59 AM occur twice. In this + * case, the ICU Calendar resolves the time using the UTC offset after the transition + * by default. For example, 1:30 AM on the date is resolved as 1:30 AM standard time. + * + * Ambiguous wall clock time resolution behaviors can be customized by Calendar APIs + * {@link #setRepeatedWallTimeOption} and {@link #setSkippedWallTimeOption}. + * These methods are available in ICU 49 or later versions. + * + * **Note:** for some non-Gregorian calendars, different + * fields may be necessary for complete disambiguation. For example, a full + * specification of the historical Arabic astronomical calendar requires year, + * month, day-of-month *and* day-of-week in some cases. + * + * **Note:** There are certain possible ambiguities in + * interpretation of certain singular times, which are resolved in the + * following ways: + * + * 1. 24:00:00 "belongs" to the following day. That is, + * 23:59 on Dec 31, 1969 < 24:00 on Jan 1, 1970 < 24:01:00 on Jan 1, 1970 + * 2. Although historically not precise, midnight also belongs to "am", + * and noon belongs to "pm", so on the same day, + * 12:00 am (midnight) < 12:01 am, and 12:00 pm (noon) < 12:01 pm + * + * The date or time format strings are not part of the definition of a + * calendar, as those must be modifiable or overridable by the user at + * runtime. Use `DateFormat` to format dates. + * + * `Calendar` provides an API for field "rolling", where fields + * can be incremented or decremented, but wrap around. For example, rolling the + * month up in the date December 12, **1996** results in + * January 12, **1996**. + * + * `Calendar` also provides a date arithmetic function for + * adding the specified (signed) amount of time to a particular time field. + * For example, subtracting 5 days from the date `September 12, 1996` + * results in `September 7, 1996`. + * + * ***Supported range*** + * + * The allowable range of `Calendar` has been narrowed. `GregorianCalendar` used + * to attempt to support the range of dates with millisecond values from + * `Long.MIN_VALUE` to `Long.MAX_VALUE`. The new `Calendar` protocol specifies the + * maximum range of supportable dates as those having Julian day numbers + * of `-0x7F000000` to `+0x7F000000`. This corresponds to years from ~5,800,000 BCE + * to ~5,800,000 CE. Programmers should use the protected constants in `Calendar` to + * specify an extremely early or extremely late date. + * + *

+ * The Japanese calendar uses a combination of era name and year number. + * When an emperor of Japan abdicates and a new emperor ascends the throne, + * a new era is declared and year number is reset to 1. Even if the date of + * abdication is scheduled ahead of time, the new era name might not be + * announced until just before the date. In such case, ICU4C may include + * a start date of future era without actual era name, but not enabled + * by default. ICU4C users who want to test the behavior of the future era + * can enable the tentative era by: + *

For example, if fieldDifference(when, + * Calendar::MONTH) returns 3, then this calendar is set to + * 3 months before when, and possibly some addition + * time less than one month. + * + *

As a side effect of this call, this calendar is advanced + * toward when by the given amount. That is, calling + * this method has the side effect of calling add(field, + * n), where n is the return value. + * + *

Usage: To use this method, call it first with the largest + * field of interest, then with progressively smaller fields. For + * example: + * + * 

+     * int y = cal->fieldDifference(when, Calendar::YEAR, err);
+     * int m = cal->fieldDifference(when, Calendar::MONTH, err);
+     * int d = cal->fieldDifference(when, Calendar::DATE, err);
+ * + * computes the difference between cal and + * when in years, months, and days. + * + *

Note: fieldDifference() is + * asymmetrical. That is, in the following code: + * + * 

+     * cal->setTime(date1, err);
+     * int m1 = cal->fieldDifference(date2, Calendar::MONTH, err);
+     * int d1 = cal->fieldDifference(date2, Calendar::DATE, err);
+     * cal->setTime(date2, err);
+     * int m2 = cal->fieldDifference(date1, Calendar::MONTH, err);
+     * int d2 = cal->fieldDifference(date1, Calendar::DATE, err);
+ * + * one might expect that m1 == -m2 && d1 == -d2. + * However, this is not generally the case, because of + * irregularities in the underlying calendar system (e.g., the + * Gregorian calendar has a varying number of days per month). + * + * @param when the date to compare this calendar's time to + * @param field the field in which to compute the result + * @param status Output param set to success/failure code on exit.

It is especially useful for wrapping + * streams with converters into an object for collation or + * normalization. + * + *

Characters can be accessed in two ways: as code units or as + * code points. + * Unicode code points are 21-bit integers and are the scalar values + * of Unicode characters. ICU uses the type UChar32 for them. + * Unicode code units are the storage units of a given + * Unicode/UCS Transformation Format (a character encoding scheme). + * With UTF-16, all code points can be represented with either one + * or two code units ("surrogates"). + * String storage is typically based on code units, while properties + * of characters are typically determined using code point values. + * Some processes may be designed to work with sequences of code units, + * or it may be known that all characters that are important to an + * algorithm can be represented with single code units. + * Other processes will need to use the code point access functions.

+ * + *

ForwardCharacterIterator provides nextPostInc() to access + * a code unit and advance an internal position into the text object, + * similar to a return text[position++].
+ * It provides next32PostInc() to access a code point and advance an internal + * position.

+ * + *

next32PostInc() assumes that the current position is that of + * the beginning of a code point, i.e., of its first code unit. + * After next32PostInc(), this will be true again. + * In general, access to code units and code points in the same + * iteration loop should not be mixed. In UTF-16, if the current position + * is on a second code unit (Low Surrogate), then only that code unit + * is returned even by next32PostInc().

+ * + *

For iteration with either function, there are two ways to + * check for the end of the iteration. When there are no more + * characters in the text object: + *

    + *
  • The hasNext() function returns false.
    • + *
  • nextPostInc() and next32PostInc() return DONE + * when one attempts to read beyond the end of the text object.
    • + *
+ * + * Example: + * \code + * void function1(ForwardCharacterIterator &it) { + * UChar32 c; + * while(it.hasNext()) { + * c=it.next32PostInc(); + * // use c + * } + * } + * + * void function1(ForwardCharacterIterator &it) { + * char16_t c; + * while((c=it.nextPostInc())!=ForwardCharacterIterator::DONE) { + * // use c + * } + * } + * \endcode + *

The API provides backward compatibility to the Java and older ICU + * CharacterIterator classes but extends them significantly: + *

    + *
  1. CharacterIterator is now a subclass of ForwardCharacterIterator.
    2. + *
  2. While the old API functions provided forward iteration with + * "pre-increment" semantics, the new one also provides functions + * with "post-increment" semantics. They are more efficient and should + * be the preferred iterator functions for new implementations. + * The backward iteration always had "pre-decrement" semantics, which + * are efficient.
    3. + *
  3. Just like ForwardCharacterIterator, it provides access to + * both code units and code points. Code point access versions are available + * for the old and the new iteration semantics.
    4. + *
  4. There are new functions for setting and moving the current position + * without returning a character, for efficiency.
    5. + *
+ * + * See ForwardCharacterIterator for examples for using the new forward iteration + * functions. For backward iteration, there is also a hasPrevious() function + * that can be used analogously to hasNext(). + * The old functions work as before and are shown below.

ChoiceFormat is probably not what you need. + * Please use MessageFormat + * with plural arguments for proper plural selection, + * and select arguments for simple selection among a fixed set of choices!

+ * + *

A ChoiceFormat splits + * the real number line \htmlonly-∞ to + * +∞\endhtmlonly into two + * or more contiguous ranges. Each range is mapped to a + * string.

+ * + *

ChoiceFormat was originally intended + * for displaying grammatically correct + * plurals such as "There is one file." vs. "There are 2 files." + * However, plural rules for many languages + * are too complex for the capabilities of ChoiceFormat, + * and its requirement of specifying the precise rules for each message + * is unmanageable for translators.

+ * + *

There are two methods of defining a ChoiceFormat; both + * are equivalent. The first is by using a string pattern. This is the + * preferred method in most cases. The second method is through direct + * specification of the arrays that logically make up the + * ChoiceFormat.

+ * + *

Note: Typically, choice formatting is done (if done at all) via MessageFormat + * with a choice argument type, + * rather than using a stand-alone ChoiceFormat.

+ * + *
Patterns and Their Interpretation
+ * + *

The pattern string defines the range boundaries and the strings for each number range. + * Syntax: + * 

+ * choiceStyle = number separator message ('|' number separator message)*
+ * number = normal_number | ['-'] \htmlonly∞\endhtmlonly (U+221E, infinity)
+ * normal_number = double value (unlocalized ASCII string)
+ * separator = less_than | less_than_or_equal
+ * less_than = '<'
+ * less_than_or_equal = '#' | \htmlonly≤\endhtmlonly (U+2264)
+ * message: see {@link MessageFormat}
+ *
+ * Pattern_White_Space between syntax elements is ignored, except + * around each range's sub-message.

+ * + *

Each numeric sub-range extends from the current range's number + * to the next range's number. + * The number itself is included in its range if a less_than_or_equal sign is used, + * and excluded from its range (and instead included in the previous range) + * if a less_than sign is used.

+ * + *

When a ChoiceFormat is constructed from + * arrays of numbers, closure flags and strings, + * they are interpreted just like + * the sequence of (number separator string) in an equivalent pattern string. + * closure[i]==true corresponds to a less_than separator sign. + * The equivalent pattern string will be constructed automatically.

+ * + *

During formatting, a number is mapped to the first range + * where the number is not greater than the range's upper limit. + * That range's message string is returned. A NaN maps to the very first range.

+ * + *

During parsing, a range is selected for the longest match of + * any range's message. That range's number is returned, ignoring the separator/closure. + * Only a simple string match is performed, without parsing of arguments that + * might be specified in the message strings.

+ * + *

Note that the first range's number is ignored in formatting + * but may be returned from parsing.

+ * + *
Examples
+ * + *

Here is an example of two arrays that map the number + * 1..7 to the English day of the week abbreviations + * Sun..Sat. No closures array is given; this is the same as + * specifying all closures to be false.

+ * + * 
    {1,2,3,4,5,6,7},
+ *     {"Sun","Mon","Tue","Wed","Thur","Fri","Sat"}
+ * + *

Here is an example that maps the ranges [-Inf, 1), [1, 1], and (1, + * +Inf] to three strings. That is, the number line is split into three + * ranges: x < 1.0, x = 1.0, and x > 1.0. + * (The round parentheses in the notation above indicate an exclusive boundary, + * like the turned bracket in European notation: [-Inf, 1) == [-Inf, 1[ )

+ * + * 
    {0, 1, 1},
+ *     {false, false, true},
+ *     {"no files", "one file", "many files"}
+ * + *

Here is an example that shows formatting and parsing:

+ * + * \code + * #include + * #include + * #include + * + * int main(int argc, char *argv[]) { + * double limits[] = {1,2,3,4,5,6,7}; + * UnicodeString monthNames[] = { + * "Sun","Mon","Tue","Wed","Thu","Fri","Sat"}; + * ChoiceFormat fmt(limits, monthNames, 7); + * UnicodeString str; + * char buf[256]; + * for (double x = 1.0; x <= 8.0; x += 1.0) { + * fmt.format(x, str); + * str.extract(0, str.length(), buf, 256, ""); + * str.truncate(0); + * cout << x << " -> " + * << buf << endl; + * } + * cout << endl; + * return 0; + * } + * \endcode + * + *

Use the iterator to return the +* ordering priority of the positioned character. The ordering priority of a +* character, which we refer to as a key, defines how a character is collated in +* the given collation object. +* For example, consider the following in Slovak and in traditional Spanish collation: +* 
+*        "ca" -> the first key is key('c') and second key is key('a').
+*        "cha" -> the first key is key('ch') and second key is key('a').
+* And in German phonebook collation, +* 
 \htmlonly       "æb"-> the first key is key('a'), the second key is key('e'), and
+*        the third key is key('b'). \endhtmlonly
+* The key of a character, is an integer composed of primary order(short), +* secondary order(char), and tertiary order(char). Java strictly defines the +* size and signedness of its primitive data types. Therefore, the static +* functions primaryOrder(), secondaryOrder(), and tertiaryOrder() return +* int32_t to ensure the correctness of the key value. +*

Example of the iterator usage: (without error checking) +* 

+* \code
+*   void CollationElementIterator_Example()
+*   {
+*       UnicodeString str = "This is a test";
+*       UErrorCode success = U_ZERO_ERROR;
+*       RuleBasedCollator* rbc =
+*           (RuleBasedCollator*) RuleBasedCollator::createInstance(success);
+*       CollationElementIterator* c =
+*           rbc->createCollationElementIterator( str );
+*       int32_t order = c->next(success);
+*       c->reset();
+*       order = c->previous(success);
+*       delete c;
+*       delete rbc;
+*   }
+* \endcode
+*
+*

+* The method next() returns the collation order of the next character based on +* the comparison level of the collator. The method previous() returns the +* collation order of the previous character based on the comparison level of +* the collator. The Collation Element Iterator moves only in one direction +* between calls to reset(), setOffset(), or setText(). That is, next() +* and previous() can not be inter-used. Whenever previous() is to be called after +* next() or vice versa, reset(), setOffset() or setText() has to be called first +* to reset the status, shifting pointers to either the end or the start of +* the string (reset() or setText()), or the specified position (setOffset()). +* Hence at the next call of next() or previous(), the first or last collation order, +* or collation order at the specified position will be returned. If a change of +* direction is done without one of these calls, the result is undefined. +*

+* The result of a forward iterate (next()) and reversed result of the backward +* iterate (previous()) on the same string are equivalent, if collation orders +* with the value 0 are ignored. +* Character based on the comparison level of the collator. A collation order +* consists of primary order, secondary order and tertiary order.

+* Like other locale-sensitive classes, you can use the static factory method, +* createInstance, to obtain the appropriate +* Collator object for a given locale. You will only need to +* look at the subclasses of Collator if you need to +* understand the details of a particular collation strategy or if you need to +* modify that strategy. +*

+* The following example shows how to compare two strings using the +* Collator for the default locale. +* \htmlonly

\endhtmlonly +* 
+* \code
+* // Compare two strings in the default locale
+* UErrorCode success = U_ZERO_ERROR;
+* Collator* myCollator = Collator::createInstance(success);
+* if (myCollator->compare("abc", "ABC") < 0)
+*   cout << "abc is less than ABC" << endl;
+* else
+*   cout << "abc is greater than or equal to ABC" << endl;
+* \endcode
+*
+* \htmlonly
\endhtmlonly +*

+* You can set a Collator's strength attribute to +* determine the level of difference considered significant in comparisons. +* Five strengths are provided: PRIMARY, SECONDARY, +* TERTIARY, QUATERNARY and IDENTICAL. +* The exact assignment of strengths to language features is locale dependent. +* For example, in Czech, "e" and "f" are considered primary differences, +* while "e" and "\u00EA" are secondary differences, "e" and "E" are tertiary +* differences and "e" and "e" are identical. The following shows how both case +* and accents could be ignored for US English. +* \htmlonly

\endhtmlonly +* 
+* \code
+* //Get the Collator for US English and set its strength to PRIMARY
+* UErrorCode success = U_ZERO_ERROR;
+* Collator* usCollator = Collator::createInstance(Locale::getUS(), success);
+* usCollator->setStrength(Collator::PRIMARY);
+* if (usCollator->compare("abc", "ABC") == 0)
+*     cout << "'abc' and 'ABC' strings are equivalent with strength PRIMARY" << endl;
+* \endcode
+*
+* \htmlonly
\endhtmlonly +* +* The getSortKey methods +* convert a string to a series of bytes that can be compared bitwise against +* other sort keys using strcmp(). Sort keys are written as +* zero-terminated byte strings. +* +* Another set of APIs returns a CollationKey object that wraps +* the sort key bytes instead of returning the bytes themselves. +*

+*

+* Note: Collators with different Locale, +* and CollationStrength settings will return different sort +* orders for the same set of strings. Locales have specific collation rules, +* and the way in which secondary and tertiary differences are taken into +* account, for example, will result in a different sorting order for same +* strings. +*

Converting from the internal representation (milliseconds + * since midnight, January 1, 1970) to text is known as "formatting," and converting + * from text to millis is known as "parsing." We currently define only one concrete + * subclass of DateFormat: SimpleDateFormat, which can handle pretty much all normal + * date formatting and parsing actions. + *

+ * DateFormat helps you to format and parse dates for any locale. Your code can + * be completely independent of the locale conventions for months, days of the + * week, or even the calendar format: lunar vs. solar. + *

+ * To format a date for the current Locale, use one of the static factory + * methods: + * 

+ * \code
+ *      DateFormat* dfmt = DateFormat::createDateInstance();
+ *      UDate myDate = Calendar::getNow();
+ *      UnicodeString myString;
+ *      myString = dfmt->format( myDate, myString );
+ * \endcode
+ *
+ * If you are formatting multiple numbers, it is more efficient to get the + * format and use it multiple times so that the system doesn't have to fetch the + * information about the local language and country conventions multiple times. + * 
+ * \code
+ *      DateFormat* df = DateFormat::createDateInstance();
+ *      UnicodeString myString;
+ *      UDate myDateArr[] = { 0.0, 100000000.0, 2000000000.0 }; // test values
+ *      for (int32_t i = 0; i < 3; ++i) {
+ *          myString.remove();
+ *          cout << df->format( myDateArr[i], myString ) << endl;
+ *      }
+ * \endcode
+ *
+ * To get specific fields of a date, you can use UFieldPosition to + * get specific fields. + * 
+ * \code
+ *      DateFormat* dfmt = DateFormat::createDateInstance();
+ *      FieldPosition pos(DateFormat::YEAR_FIELD);
+ *      UnicodeString myString;
+ *      myString = dfmt->format( myDate, myString );
+ *      cout << myString << endl;
+ *      cout << pos.getBeginIndex() << "," << pos. getEndIndex() << endl;
+ * \endcode
+ *
+ * To format a date for a different Locale, specify it in the call to + * createDateInstance(). + * 
+ * \code
+ *       DateFormat* df =
+ *           DateFormat::createDateInstance( DateFormat::SHORT, Locale::getFrance());
+ * \endcode
+ *
+ * You can use a DateFormat to parse also. + * 
+ * \code
+ *       UErrorCode status = U_ZERO_ERROR;
+ *       UDate myDate = df->parse(myString, status);
+ * \endcode
+ *
+ * Use createDateInstance() to produce the normal date format for that country. + * There are other static factory methods available. Use createTimeInstance() + * to produce the normal time format for that country. Use createDateTimeInstance() + * to produce a DateFormat that formats both date and time. You can pass in + * different options to these factory methods to control the length of the + * result; from SHORT to MEDIUM to LONG to FULL. The exact result depends on the + * locale, but generally: + *
    + *
  • SHORT is completely numeric, such as 12/13/52 or 3:30pm + *
  • MEDIUM is longer, such as Jan 12, 1952 + *
  • LONG is longer, such as January 12, 1952 or 3:30:32pm + *
  • FULL is pretty completely specified, such as + * Tuesday, April 12, 1952 AD or 3:30:42pm PST. + *
+ * You can also set the time zone on the format if you wish. If you want even + * more control over the format or parsing, (or want to give your users more + * control), you can try casting the DateFormat you get from the factory methods + * to a SimpleDateFormat. This will work for the majority of countries; just + * remember to check getDynamicClassID() before carrying out the cast. + *

+ * You can also use forms of the parse and format methods with ParsePosition and + * FieldPosition to allow you to + *

    + *
  • Progressively parse through pieces of a string. + *
  • Align any particular field, or find out where it is for selection + * on the screen. + *

Patterns + * + *

A DecimalFormat consists of a pattern and a set of + * symbols. The pattern may be set directly using + * applyPattern(), or indirectly using other API methods which + * manipulate aspects of the pattern, such as the minimum number of integer + * digits. The symbols are stored in a DecimalFormatSymbols + * object. When using the NumberFormat factory methods, the + * pattern and symbols are read from ICU's locale data. + * + *

Special Pattern Characters + * + *

Many characters in a pattern are taken literally; they are matched during + * parsing and output unchanged during formatting. Special characters, on the + * other hand, stand for other characters, strings, or classes of characters. + * For example, the '#' character is replaced by a localized digit. Often the + * replacement character is the same as the pattern character; in the U.S. locale, + * the ',' grouping character is replaced by ','. However, the replacement is + * still happening, and if the symbols are modified, the grouping character + * changes. Some special characters affect the behavior of the formatter by + * their presence; for example, if the percent character is seen, then the + * value is multiplied by 100 before being displayed. + * + *

To insert a special character in a pattern as a literal, that is, without + * any special meaning, the character must be quoted. There are some exceptions to + * this which are noted below. + * + *

The characters listed here are used in non-localized patterns. Localized + * patterns use the corresponding characters taken from this formatter's + * DecimalFormatSymbols object instead, and these characters lose + * their special status. Two exceptions are the currency sign and quote, which + * are not localized. + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + *
Symbol + * Location + * Localized? + * Meaning + *
0 + * Number + * Yes + * Digit + *
1-9 + * Number + * Yes + * '1' through '9' indicate rounding. + *
\htmlonly@\endhtmlonly + * Number + * No + * Significant digit + *
# + * Number + * Yes + * Digit, zero shows as absent + *
. + * Number + * Yes + * Decimal separator or monetary decimal separator + *
- + * Number + * Yes + * Minus sign + *
, + * Number + * Yes + * Grouping separator + *
E + * Number + * Yes + * Separates mantissa and exponent in scientific notation. + * Need not be quoted in prefix or suffix. + *
+ + * Exponent + * Yes + * Prefix positive exponents with localized plus sign. + * Need not be quoted in prefix or suffix. + *
; + * Subpattern boundary + * Yes + * Separates positive and negative subpatterns + *
\% + * Prefix or suffix + * Yes + * Multiply by 100 and show as percentage + *
\\u2030 + * Prefix or suffix + * Yes + * Multiply by 1000 and show as per mille + *
\htmlonly¤\endhtmlonly (\\u00A4) + * Prefix or suffix + * No + * Currency sign, replaced by currency symbol. If + * doubled, replaced by international currency symbol. + * If tripled, replaced by currency plural names, for example, + * "US dollar" or "US dollars" for America. + * If present in a pattern, the monetary decimal separator + * is used instead of the decimal separator. + *
' + * Prefix or suffix + * No + * Used to quote special characters in a prefix or suffix, + * for example, "'#'#" formats 123 to + * "#123". To create a single quote + * itself, use two in a row: "# o''clock". + *
* + * Prefix or suffix boundary + * Yes + * Pad escape, precedes pad character + *
+ * + *

A DecimalFormat pattern contains a positive and negative + * subpattern, for example, "#,##0.00;(#,##0.00)". Each subpattern has a + * prefix, a numeric part, and a suffix. If there is no explicit negative + * subpattern, the negative subpattern is the localized minus sign prefixed to the + * positive subpattern. That is, "0.00" alone is equivalent to "0.00;-0.00". If there + * is an explicit negative subpattern, it serves only to specify the negative + * prefix and suffix; the number of digits, minimal digits, and other + * characteristics are ignored in the negative subpattern. That means that + * "#,##0.0#;(#)" has precisely the same result as "#,##0.0#;(#,##0.0#)". + * + *

The prefixes, suffixes, and various symbols used for infinity, digits, + * thousands separators, decimal separators, etc. may be set to arbitrary + * values, and they will appear properly during formatting. However, care must + * be taken that the symbols and strings do not conflict, or parsing will be + * unreliable. For example, either the positive and negative prefixes or the + * suffixes must be distinct for parse() to be able + * to distinguish positive from negative values. Another example is that the + * decimal separator and thousands separator should be distinct characters, or + * parsing will be impossible. + * + *

The grouping separator is a character that separates clusters of + * integer digits to make large numbers more legible. It commonly used for + * thousands, but in some locales it separates ten-thousands. The grouping + * size is the number of digits between the grouping separators, such as 3 + * for "100,000,000" or 4 for "1 0000 0000". There are actually two different + * grouping sizes: One used for the least significant integer digits, the + * primary grouping size, and one used for all others, the + * secondary grouping size. In most locales these are the same, but + * sometimes they are different. For example, if the primary grouping interval + * is 3, and the secondary is 2, then this corresponds to the pattern + * "#,##,##0", and the number 123456789 is formatted as "12,34,56,789". If a + * pattern contains multiple grouping separators, the interval between the last + * one and the end of the integer defines the primary grouping size, and the + * interval between the last two defines the secondary grouping size. All others + * are ignored, so "#,##,###,####" == "###,###,####" == "##,#,###,####". + * + *

Illegal patterns, such as "#.#.#" or "#.###,###", will cause + * DecimalFormat to set a failing UErrorCode. + * + *

Pattern BNF + * + *

+ * The first subpattern is for positive numbers. The second (optional) + * subpattern is for negative numbers. + * + *

Not indicated in the BNF syntax above: + * + *

  • The grouping separator ',' can occur inside the integer and + * sigDigits elements, between any two pattern characters of that + * element, as long as the integer or sigDigits element is not + * followed by the exponent element. + * + *
  • Two grouping intervals are recognized: That between the + * decimal point and the first grouping symbol, and that + * between the first and second grouping symbols. These + * intervals are identical in most locales, but in some + * locales they differ. For example, the pattern + * "#,##,###" formats the number 123456789 as + * "12,34,56,789".
    • + * + *
  • The pad specifier padSpec may appear before the prefix, + * after the prefix, before the suffix, after the suffix, or not at all. + * + *
  • In place of '0', the digits '1' through '9' may be used to + * indicate a rounding increment. + *
+ * + *

Parsing + * + *

DecimalFormat parses all Unicode characters that represent + * decimal digits, as defined by u_charDigitValue(). In addition, + * DecimalFormat also recognizes as digits the ten consecutive + * characters starting with the localized zero digit defined in the + * DecimalFormatSymbols object. During formatting, the + * DecimalFormatSymbols-based digits are output. + * + *

During parsing, grouping separators are ignored if in lenient mode; + * otherwise, if present, they must be in appropriate positions. + * + *

For currency parsing, the formatter is able to parse every currency + * style formats no matter which style the formatter is constructed with. + * For example, a formatter instance gotten from + * NumberFormat.getInstance(ULocale, NumberFormat.CURRENCYSTYLE) can parse + * formats such as "USD1.00" and "3.00 US dollars". + * + *

If parse(UnicodeString&,Formattable&,ParsePosition&) + * fails to parse a string, it leaves the parse position unchanged. + * The convenience method parse(UnicodeString&,Formattable&,UErrorCode&) + * indicates parse failure by setting a failing + * UErrorCode. + * + *

Formatting + * + *

Formatting is guided by several parameters, all of which can be + * specified either using a pattern or using the API. The following + * description applies to formats that do not use scientific + * notation or significant digits. + * + *

  • If the number of actual integer digits exceeds the + * maximum integer digits, then only the least significant + * digits are shown. For example, 1997 is formatted as "97" if the + * maximum integer digits is set to 2. + * + *
  • If the number of actual integer digits is less than the + * minimum integer digits, then leading zeros are added. For + * example, 1997 is formatted as "01997" if the minimum integer digits + * is set to 5. + * + *
  • If the number of actual fraction digits exceeds the maximum + * fraction digits, then rounding is performed to the + * maximum fraction digits. For example, 0.125 is formatted as "0.12" + * if the maximum fraction digits is 2. This behavior can be changed + * by specifying a rounding increment and/or a rounding mode. + * + *
  • If the number of actual fraction digits is less than the + * minimum fraction digits, then trailing zeros are added. + * For example, 0.125 is formatted as "0.1250" if the minimum fraction + * digits is set to 4. + * + *
  • Trailing fractional zeros are not displayed if they occur + * j positions after the decimal, where j is less + * than the maximum fraction digits. For example, 0.10004 is + * formatted as "0.1" if the maximum fraction digits is four or less. + *
+ * + *

Special Values + * + *

NaN is represented as a single character, typically + * \\uFFFD. This character is determined by the + * DecimalFormatSymbols object. This is the only value for which + * the prefixes and suffixes are not used. + * + *

Infinity is represented as a single character, typically + * \\u221E, with the positive or negative prefixes and suffixes + * applied. The infinity character is determined by the + * DecimalFormatSymbols object. + * + * Scientific Notation + * + *

Numbers in scientific notation are expressed as the product of a mantissa + * and a power of ten, for example, 1234 can be expressed as 1.234 x 103. The + * mantissa is typically in the half-open interval [1.0, 10.0) or sometimes [0.0, 1.0), + * but it need not be. DecimalFormat supports arbitrary mantissas. + * DecimalFormat can be instructed to use scientific + * notation through the API or through the pattern. In a pattern, the exponent + * character immediately followed by one or more digit characters indicates + * scientific notation. Example: "0.###E0" formats the number 1234 as + * "1.234E3". + * + *

    + *
  • The number of digit characters after the exponent character gives the + * minimum exponent digit count. There is no maximum. Negative exponents are + * formatted using the localized minus sign, not the prefix and suffix + * from the pattern. This allows patterns such as "0.###E0 m/s". To prefix + * positive exponents with a localized plus sign, specify '+' between the + * exponent and the digits: "0.###E+0" will produce formats "1E+1", "1E+0", + * "1E-1", etc. (In localized patterns, use the localized plus sign rather than + * '+'.) + * + *
  • The minimum number of integer digits is achieved by adjusting the + * exponent. Example: 0.00123 formatted with "00.###E0" yields "12.3E-4". This + * only happens if there is no maximum number of integer digits. If there is a + * maximum, then the minimum number of integer digits is fixed at one. + * + *
  • The maximum number of integer digits, if present, specifies the exponent + * grouping. The most common use of this is to generate engineering + * notation, in which the exponent is a multiple of three, e.g., + * "##0.###E0". The number 12345 is formatted using "##0.####E0" as "12.345E3". + * + *
  • When using scientific notation, the formatter controls the + * digit counts using significant digits logic. The maximum number of + * significant digits limits the total number of integer and fraction + * digits that will be shown in the mantissa; it does not affect + * parsing. For example, 12345 formatted with "##0.##E0" is "12.3E3". + * See the section on significant digits for more details. + * + *
  • The number of significant digits shown is determined as + * follows: If areSignificantDigitsUsed() returns false, then the + * minimum number of significant digits shown is one, and the maximum + * number of significant digits shown is the sum of the minimum + * integer and maximum fraction digits, and is + * unaffected by the maximum integer digits. If this sum is zero, + * then all significant digits are shown. If + * areSignificantDigitsUsed() returns true, then the significant digit + * counts are specified by getMinimumSignificantDigits() and + * getMaximumSignificantDigits(). In this case, the number of + * integer digits is fixed at one, and there is no exponent grouping. + * + *
  • Exponential patterns may not contain grouping separators. + *
+ * + * Significant Digits + * + * DecimalFormat has two ways of controlling how many + * digits are shows: (a) significant digits counts, or (b) integer and + * fraction digit counts. Integer and fraction digit counts are + * described above. When a formatter is using significant digits + * counts, the number of integer and fraction digits is not specified + * directly, and the formatter settings for these counts are ignored. + * Instead, the formatter uses however many integer and fraction + * digits are required to display the specified number of significant + * digits. Examples: + * + * + * + * + * + * + * + *
Pattern + * Minimum significant digits + * Maximum significant digits + * Number + * Output of format() + *
\@\@\@ + * 3 + * 3 + * 12345 + * 12300 + *
\@\@\@ + * 3 + * 3 + * 0.12345 + * 0.123 + *
\@\@## + * 2 + * 4 + * 3.14159 + * 3.142 + *
\@\@## + * 2 + * 4 + * 1.23004 + * 1.23 + *
+ * + *
    + *
  • Significant digit counts may be expressed using patterns that + * specify a minimum and maximum number of significant digits. These + * are indicated by the '@' and '#' + * characters. The minimum number of significant digits is the number + * of '@' characters. The maximum number of significant + * digits is the number of '@' characters plus the number + * of '#' characters following on the right. For + * example, the pattern "@@@" indicates exactly 3 + * significant digits. The pattern "@##" indicates from + * 1 to 3 significant digits. Trailing zero digits to the right of + * the decimal separator are suppressed after the minimum number of + * significant digits have been shown. For example, the pattern + * "@##" formats the number 0.1203 as + * "0.12". + * + *
  • If a pattern uses significant digits, it may not contain a + * decimal separator, nor the '0' pattern character. + * Patterns such as "@00" or "@.###" are + * disallowed. + * + *
  • Any number of '#' characters may be prepended to + * the left of the leftmost '@' character. These have no + * effect on the minimum and maximum significant digits counts, but + * may be used to position grouping separators. For example, + * "#,#@#" indicates a minimum of one significant digits, + * a maximum of two significant digits, and a grouping size of three. + * + *
  • In order to enable significant digits formatting, use a pattern + * containing the '@' pattern character. Alternatively, + * call setSignificantDigitsUsed(true). + * + *
  • In order to disable significant digits formatting, use a + * pattern that does not contain the '@' pattern + * character. Alternatively, call setSignificantDigitsUsed(false). + * + *
  • The number of significant digits has no effect on parsing. + * + *
  • Significant digits may be used together with exponential notation. Such + * patterns are equivalent to a normal exponential pattern with a minimum and + * maximum integer digit count of one, a minimum fraction digit count of + * getMinimumSignificantDigits() - 1, and a maximum fraction digit + * count of getMaximumSignificantDigits() - 1. For example, the + * pattern "@@###E0" is equivalent to "0.0###E0". + * + *
  • If significant digits are in use, then the integer and fraction + * digit counts, as set via the API, are ignored. If significant + * digits are not in use, then the significant digit counts, as set via + * the API, are ignored. + * + *
+ * + *

Padding + * + *

DecimalFormat supports padding the result of + * format() to a specific width. Padding may be specified either + * through the API or through the pattern syntax. In a pattern the pad escape + * character, followed by a single pad character, causes padding to be parsed + * and formatted. The pad escape character is '*' in unlocalized patterns, and + * can be localized using DecimalFormatSymbols::setSymbol() with a + * DecimalFormatSymbols::kPadEscapeSymbol + * selector. For example, "$*x#,##0.00" formats 123 to + * "$xx123.00", and 1234 to "$1,234.00". + * + *

    + *
  • When padding is in effect, the width of the positive subpattern, + * including prefix and suffix, determines the format width. For example, in + * the pattern "* #0 o''clock", the format width is 10. + * + *
  • The width is counted in 16-bit code units (char16_ts). + * + *
  • Some parameters which usually do not matter have meaning when padding is + * used, because the pattern width is significant with padding. In the pattern + * "* ##,##,#,##0.##", the format width is 14. The initial characters "##,##," + * do not affect the grouping size or maximum integer digits, but they do affect + * the format width. + * + *
  • Padding may be inserted at one of four locations: before the prefix, + * after the prefix, before the suffix, or after the suffix. If padding is + * specified in any other location, applyPattern() + * sets a failing UErrorCode. If there is no prefix, + * before the prefix and after the prefix are equivalent, likewise for the + * suffix. + * + *
  • When specified in a pattern, the 32-bit code point immediately + * following the pad escape is the pad character. This may be any character, + * including a special pattern character. That is, the pad escape + * escapes the following character. If there is no character after + * the pad escape, then the pattern is illegal. + * + *
+ * + *

Rounding + * + *

DecimalFormat supports rounding to a specific increment. For + * example, 1230 rounded to the nearest 50 is 1250. 1.234 rounded to the + * nearest 0.65 is 1.3. The rounding increment may be specified through the API + * or in a pattern. To specify a rounding increment in a pattern, include the + * increment in the pattern itself. "#,#50" specifies a rounding increment of + * 50. "#,##0.05" specifies a rounding increment of 0.05. + * + *

In the absence of an explicit rounding increment numbers are + * rounded to their formatted width. + * + *

    + *
  • Rounding only affects the string produced by formatting. It does + * not affect parsing or change any numerical values. + * + *
  • A rounding mode determines how values are rounded; see + * DecimalFormat::ERoundingMode. The default rounding mode is + * DecimalFormat::kRoundHalfEven. The rounding mode can only be set + * through the API; it can not be set with a pattern. + * + *
  • Some locales use rounding in their currency formats to reflect the + * smallest currency denomination. + * + *
  • In a pattern, digits '1' through '9' specify rounding, but otherwise + * behave identically to digit '0'. + *
+ * + *

Synchronization + * + *

DecimalFormat objects are not synchronized. Multiple + * threads should not access one formatter concurrently. + * + *

DateFormatSymbols is used by + * DateFormat and SimpleDateFormat. + *

+ * Rather than first creating a DateFormatSymbols to get a date-time formatter + * by using a SimpleDateFormat constructor, clients are encouraged to create a + * date-time formatter using the getTimeInstance(), getDateInstance(), or + * getDateTimeInstance() method in DateFormat. Each of these methods can return a + * date/time formatter initialized with a default format pattern along with the + * date-time formatting data for a given or default locale. After a formatter is + * created, clients may modify the format pattern using the setPattern function + * as so desired. For more information on using these formatter factory + * functions, see DateFormat. + *

+ * If clients decide to create a date-time formatter with a particular format + * pattern and locale, they can do so with new SimpleDateFormat(aPattern, + * new DateFormatSymbols(aLocale)). This will load the appropriate date-time + * formatting data from the locale. + *

+ * DateFormatSymbols objects are clonable. When clients obtain a + * DateFormatSymbols object, they can feel free to modify the date-time + * formatting data as necessary. For instance, clients can + * replace the localized date-time format pattern characters with the ones that + * they feel easy to remember. Or they can change the representative cities + * originally picked by default to using their favorite ones. + *

+ * DateFormatSymbols are not expected to be subclassed. Data for a calendar is + * loaded out of resource bundles. The 'type' parameter indicates the type of + * calendar, for example, "gregorian" or "japanese". If the type is not gregorian + * (or nullptr, or an empty string) then the type is appended to the resource name, + * for example, 'Eras_japanese' instead of 'Eras'. If the resource 'Eras_japanese' did + * not exist (even in root), then this class will fall back to just 'Eras', that is, + * Gregorian data.

+ * Date interval means from one date to another date, + * for example, from "Jan 11, 2008" to "Jan 18, 2008". + * We introduced class DateInterval to represent it. + * DateInterval is a pair of UDate, which is + * the standard milliseconds since 24:00 GMT, Jan 1, 1970. + * + *

+ * DateIntervalFormat formats a DateInterval into + * text as compactly as possible. + * For example, the date interval format from "Jan 11, 2008" to "Jan 18,. 2008" + * is "Jan 11-18, 2008" for English. + * And it parses text into DateInterval, + * although initially, parsing is not supported. + * + *

+ * There is no structural information in date time patterns. + * For any punctuations and string literals inside a date time pattern, + * we do not know whether it is just a separator, or a prefix, or a suffix. + * Without such information, so, it is difficult to generate a sub-pattern + * (or super-pattern) by algorithm. + * So, formatting a DateInterval is pattern-driven. It is very + * similar to formatting in SimpleDateFormat. + * We introduce class DateIntervalInfo to save date interval + * patterns, similar to date time pattern in SimpleDateFormat. + * + *

+ * Logically, the interval patterns are mappings + * from (skeleton, the_largest_different_calendar_field) + * to (date_interval_pattern). + * + *

+ * A skeleton + *

    + *
  1. + * only keeps the field pattern letter and ignores all other parts + * in a pattern, such as space, punctuations, and string literals. + *
    2. + *
  2. + * hides the order of fields. + *
    3. + *
  3. + * might hide a field's pattern letter length. + *
    4. + *
+ * + * For those non-digit calendar fields, the pattern letter length is + * important, such as MMM, MMMM, and MMMMM; EEE and EEEE, + * and the field's pattern letter length is honored. + * + * For the digit calendar fields, such as M or MM, d or dd, yy or yyyy, + * the field pattern length is ignored and the best match, which is defined + * in date time patterns, will be returned without honor the field pattern + * letter length in skeleton. + * + *

+ * The calendar fields we support for interval formatting are: + * year, month, date, day-of-week, am-pm, hour, hour-of-day, minute, second, + * and millisecond. + * (though we do not currently have specific intervalFormat date for skeletons + * with seconds and millisecond). + * Those calendar fields can be defined in the following order: + * year > month > date > hour (in day) > minute > second > millisecond + * + * The largest different calendar fields between 2 calendars is the + * first different calendar field in above order. + * + * For example: the largest different calendar fields between "Jan 10, 2007" + * and "Feb 20, 2008" is year. + * + *

+ * For other calendar fields, the compact interval formatting is not + * supported. And the interval format will be fall back to fall-back + * patterns, which is mostly "{date0} - {date1}". + * + *

+ * There is a set of pre-defined static skeleton strings. + * There are pre-defined interval patterns for those pre-defined skeletons + * in locales' resource files. + * For example, for a skeleton UDAT_YEAR_ABBR_MONTH_DAY, which is "yMMMd", + * in en_US, if the largest different calendar field between date1 and date2 + * is "year", the date interval pattern is "MMM d, yyyy - MMM d, yyyy", + * such as "Jan 10, 2007 - Jan 10, 2008". + * If the largest different calendar field between date1 and date2 is "month", + * the date interval pattern is "MMM d - MMM d, yyyy", + * such as "Jan 10 - Feb 10, 2007". + * If the largest different calendar field between date1 and date2 is "day", + * the date interval pattern is "MMM d-d, yyyy", such as "Jan 10-20, 2007". + * + * For date skeleton, the interval patterns when year, or month, or date is + * different are defined in resource files. + * For time skeleton, the interval patterns when am/pm, or hour, or minute is + * different are defined in resource files. + * + *

+ * If a skeleton is not found in a locale's DateIntervalInfo, which means + * the interval patterns for the skeleton is not defined in resource file, + * the interval pattern will falls back to the interval "fallback" pattern + * defined in resource file. + * If the interval "fallback" pattern is not defined, the default fall-back + * is "{date0} - {data1}". + * + *

+ * For the combination of date and time, + * The rule to generate interval patterns are: + *

    + *
  1. + * when the year, month, or day differs, falls back to fall-back + * interval pattern, which mostly is the concatenate the two original + * expressions with a separator between, + * For example, interval pattern from "Jan 10, 2007 10:10 am" + * to "Jan 11, 2007 10:10am" is + * "Jan 10, 2007 10:10 am - Jan 11, 2007 10:10am" + *
    2. + *
  2. + * otherwise, present the date followed by the range expression + * for the time. + * For example, interval pattern from "Jan 10, 2007 10:10 am" + * to "Jan 10, 2007 11:10am" is "Jan 10, 2007 10:10 am - 11:10am" + *
    3. + *
+ * + * + *

+ * If two dates are the same, the interval pattern is the single date pattern. + * For example, interval pattern from "Jan 10, 2007" to "Jan 10, 2007" is + * "Jan 10, 2007". + * + * Or if the presenting fields between 2 dates have the exact same values, + * the interval pattern is the single date pattern. + * For example, if user only requests year and month, + * the interval pattern from "Jan 10, 2007" to "Jan 20, 2007" is "Jan 2007". + * + *

+ * DateIntervalFormat needs the following information for correct + * formatting: time zone, calendar type, pattern, date format symbols, + * and date interval patterns. + * It can be instantiated in 2 ways: + *

    + *
  1. + * create an instance using default or given locale plus given skeleton. + * Users are encouraged to created date interval formatter this way and + * to use the pre-defined skeleton macros, such as + * UDAT_YEAR_NUM_MONTH, which consists the calendar fields and + * the format style. + *
    2. + *
  2. + * create an instance using default or given locale plus given skeleton + * plus a given DateIntervalInfo. + * This factory method is for powerful users who want to provide their own + * interval patterns. + * Locale provides the timezone, calendar, and format symbols information. + * Local plus skeleton provides full pattern information. + * DateIntervalInfo provides the date interval patterns. + *
    3. + *
+ * + *

+ * For the calendar field pattern letter, such as G, y, M, d, a, h, H, m, s etc. + * DateIntervalFormat uses the same syntax as that of + * DateTime format. + * + *

+ * Code Sample: general usage + * 

+ * \code
+ *   // the date interval object which the DateIntervalFormat formats on
+ *   // and parses into
+ *   DateInterval*  dtInterval = new DateInterval(1000*3600*24, 1000*3600*24*2);

It is used by DateIntervalFormat. + * + *

+ * For most users, ordinary use of DateIntervalFormat does not need to create + * DateIntervalInfo object directly. + * DateIntervalFormat will take care of it when creating a date interval + * formatter when user pass in skeleton and locale. + * + *

+ * For power users, who want to create their own date interval patterns, + * or want to re-set date interval patterns, they could do so by + * directly creating DateIntervalInfo and manipulating it. + * + *

+ * Logically, the interval patterns are mappings + * from (skeleton, the_largest_different_calendar_field) + * to (date_interval_pattern). + * + *

+ * A skeleton + *

    + *
  1. + * only keeps the field pattern letter and ignores all other parts + * in a pattern, such as space, punctuations, and string literals. + *
  2. + * hides the order of fields. + *
  3. + * might hide a field's pattern letter length. + * + * For those non-digit calendar fields, the pattern letter length is + * important, such as MMM, MMMM, and MMMMM; EEE and EEEE, + * and the field's pattern letter length is honored. + * + * For the digit calendar fields, such as M or MM, d or dd, yy or yyyy, + * the field pattern length is ignored and the best match, which is defined + * in date time patterns, will be returned without honor the field pattern + * letter length in skeleton. + *
+ * + *

+ * The calendar fields we support for interval formatting are: + * year, month, date, day-of-week, am-pm, hour, hour-of-day, and minute. + * Those calendar fields can be defined in the following order: + * year > month > date > am-pm > hour > minute + * + * The largest different calendar fields between 2 calendars is the + * first different calendar field in above order. + * + * For example: the largest different calendar fields between "Jan 10, 2007" + * and "Feb 20, 2008" is year. + * + *

+ * There is a set of pre-defined static skeleton strings. + * There are pre-defined interval patterns for those pre-defined skeletons + * in locales' resource files. + * For example, for a skeleton UDAT_YEAR_ABBR_MONTH_DAY, which is "yMMMd", + * in en_US, if the largest different calendar field between date1 and date2 + * is "year", the date interval pattern is "MMM d, yyyy - MMM d, yyyy", + * such as "Jan 10, 2007 - Jan 10, 2008". + * If the largest different calendar field between date1 and date2 is "month", + * the date interval pattern is "MMM d - MMM d, yyyy", + * such as "Jan 10 - Feb 10, 2007". + * If the largest different calendar field between date1 and date2 is "day", + * the date interval pattern is "MMM d-d, yyyy", such as "Jan 10-20, 2007". + * + * For date skeleton, the interval patterns when year, or month, or date is + * different are defined in resource files. + * For time skeleton, the interval patterns when am/pm, or hour, or minute is + * different are defined in resource files. + * + * + *

+ * There are 2 dates in interval pattern. For most locales, the first date + * in an interval pattern is the earlier date. There might be a locale in which + * the first date in an interval pattern is the later date. + * We use fallback format for the default order for the locale. + * For example, if the fallback format is "{0} - {1}", it means + * the first date in the interval pattern for this locale is earlier date. + * If the fallback format is "{1} - {0}", it means the first date is the + * later date. + * For a particular interval pattern, the default order can be overridden + * by prefixing "latestFirst:" or "earliestFirst:" to the interval pattern. + * For example, if the fallback format is "{0}-{1}", + * but for skeleton "yMMMd", the interval pattern when day is different is + * "latestFirst:d-d MMM yy", it means by default, the first date in interval + * pattern is the earlier date. But for skeleton "yMMMd", when day is different, + * the first date in "d-d MMM yy" is the later date. + * + *

+ * The recommended way to create a DateIntervalFormat object is to pass in + * the locale. + * By using a Locale parameter, the DateIntervalFormat object is + * initialized with the pre-defined interval patterns for a given or + * default locale. + *

+ * Users can also create DateIntervalFormat object + * by supplying their own interval patterns. + * It provides flexibility for power users. + * + *

+ * After a DateIntervalInfo object is created, clients may modify + * the interval patterns using setIntervalPattern function as so desired. + * Currently, users can only set interval patterns when the following + * calendar fields are different: ERA, YEAR, MONTH, DATE, DAY_OF_MONTH, + * DAY_OF_WEEK, AM_PM, HOUR, HOUR_OF_DAY, MINUTE, SECOND, and MILLISECOND. + * Interval patterns when other calendar fields are different is not supported. + *

+ * DateIntervalInfo objects are cloneable. + * When clients obtain a DateIntervalInfo object, + * they can feel free to modify it as necessary. + *

+ * DateIntervalInfo are not expected to be subclassed. + * Data for a calendar is loaded out of resource bundles. + * Through ICU 4.4, date interval patterns are only supported in the Gregorian + * calendar; non-Gregorian calendars are supported from ICU 4.4.1. + * @stable ICU 4.0 +**/ +class U_I18N_API DateIntervalInfo final : public UObject { +public: + /** + * Default constructor. + * It does not initialize any interval patterns except + * that it initialize default fall-back pattern as "{0} - {1}", + * which can be reset by setFallbackIntervalPattern(). + * It should be followed by setFallbackIntervalPattern() and + * setIntervalPattern(), + * and is recommended to be used only for power users who + * wants to create their own interval patterns and use them to create + * date interval formatter. + * @param status output param set to success/failure code on exit + * @internal ICU 4.0 + */ + DateIntervalInfo(UErrorCode& status); + + + /** + * Construct DateIntervalInfo for the given locale, + * @param locale the interval patterns are loaded from the appropriate calendar + * data (specified calendar or default calendar) in this locale. + * @param status output param set to success/failure code on exit + * @stable ICU 4.0 + */ + DateIntervalInfo(const Locale& locale, UErrorCode& status); + + + /** + * Copy constructor. + * @stable ICU 4.0 + */ + DateIntervalInfo(const DateIntervalInfo&); + + /** + * Assignment operator + * @stable ICU 4.0 + */ + DateIntervalInfo& operator=(const DateIntervalInfo&); + + /** + * Clone this object polymorphically. + * The caller owns the result and should delete it when done. + * @return a copy of the object + * @stable ICU 4.0 + */ + virtual DateIntervalInfo* clone() const; + + /** + * Destructor. + * It is virtual to be safe, but it is not designed to be subclassed. + * @stable ICU 4.0 + */ + virtual ~DateIntervalInfo(); + + + /** + * Return true if another object is semantically equal to this one. + * + * @param other the DateIntervalInfo object to be compared with. + * @return true if other is semantically equal to this. + * @stable ICU 4.0 + */ + virtual bool operator==(const DateIntervalInfo& other) const; + + /** + * Return true if another object is semantically unequal to this one. + * + * @param other the DateIntervalInfo object to be compared with. + * @return true if other is semantically unequal to this. + * @stable ICU 4.0 + */ + bool operator!=(const DateIntervalInfo& other) const; + + + + /** + * Provides a way for client to build interval patterns. + * User could construct DateIntervalInfo by providing a list of skeletons + * and their patterns. + *

+ * FieldPosition keeps track of the position of the + * field within the formatted output with two indices: the index + * of the first character of the field and the index of the last + * character of the field. + * + *

+ * \code
+ *       double doubleNum[] = {123456789.0, -12345678.9, 1234567.89, -123456.789,

+ *       DecimalFormat* fmt = (DecimalFormat*) NumberFormat::createInstance(status);
+ *       fmt->setDecimalSeparatorAlwaysShown(true);
+ *       
+ *       const int tempLen = 20;
+ *       char temp[tempLen];
+ *       
+ *       for (int i=0; iformat(doubleNum[i], buf, pos), fmtText);
+ *           for (int j=0; j

+/**
+ * Base class for all formats.  This is an abstract base class which
+ * specifies the protocol for classes which convert other objects or
+ * values, such as numeric values and dates, and their string
+ * representations.  In some cases these representations may be
+ * localized or contain localized characters or strings.  For example,
+ * a numeric formatter such as DecimalFormat may convert a numeric
+ * value such as 12345 to the string "$12,345".  It may also parse
+ * the string back into a numeric value.  A date and time formatter
+ * like SimpleDateFormat may represent a specific date, encoded
+ * numerically, as a string such as "Wednesday, February 26, 1997 AD".
+ * 

+ * Many of the concrete subclasses of Format employ the notion of
+ * a pattern.  A pattern is a string representation of the rules which
+ * govern the interconversion between values and strings.  For example,
+ * a DecimalFormat object may be associated with the pattern
+ * "$#,##0.00;($#,##0.00)", which is a common US English format for
+ * currency values, yielding strings such as "$1,234.45" for 1234.45,
+ * and "($987.65)" for 987.6543.  The specific syntax of a pattern
+ * is defined by each subclass.
+ * 

+ * Even though many subclasses use patterns, the notion of a pattern
+ * is not inherent to Format classes in general, and is not part of
+ * the explicit base class protocol.
+ * 

+ * Two complex formatting classes bear mentioning.  These are
+ * MessageFormat and ChoiceFormat.  ChoiceFormat is a subclass of
+ * NumberFormat which allows the user to format different number ranges
+ * as strings.  For instance, 0 may be represented as "no files", 1 as
+ * "one file", and any number greater than 1 as "many files".
+ * MessageFormat is a formatter which utilizes other Format objects to
+ * format a string containing with multiple values.  For instance,
+ * A MessageFormat object might produce the string "There are no files
+ * on the disk MyDisk on February 27, 1997." given the arguments 0,
+ * "MyDisk", and the date value of 2/27/97.  See the ChoiceFormat
+ * and MessageFormat headers for further information.
+ * 

+ * If formatting is unsuccessful, a failing UErrorCode is returned when
+ * the Format cannot format the type of object, otherwise if there is
+ * something illformed about the the Unicode replacement character
+ * 0xFFFD is returned.
+ * 

+ * If there is no match when parsing, a parse failure UErrorCode is
+ * returned for methods which take no ParsePosition.  For the method
+ * that takes a ParsePosition, the index parameter is left unchanged.
+ * 

+ * User subclasses are not supported. While clients may write
+ * subclasses, such code will not necessarily work and will not be
+ * guaranteed to work stably from release to release.

+     * Parse a string to produce an object.  This is a pure virtual
+     * method which subclasses must implement.  This method allows
+     * polymorphic parsing of strings into Formattable objects.
+     * 

+     * Before calling, set parse_pos.index to the offset you want to
+     * start parsing at in the source.  After calling, parse_pos.index
+     * is the end of the text you parsed.  If error occurs, index is
+     * unchanged.
+     * 

+     * When parsing, leading whitespace is discarded (with successful
+     * parse), while trailing whitespace is left as is.
+     * 

+     * Example:
+     * 

+     * Parsing "_12_xy" (where _ represents a space) for a number,
+     * with index == 0 will result in the number 12, with
+     * parse_pos.index updated to 3 (just before the second space).
+     * Parsing a second time will result in a failing UErrorCode since
+     * "xy" is not a number, and leave index at 3.
+     * 

+     * Subclasses will typically supply specific parse methods that
+     * return different types of values. Since methods can't overload
+     * on return types, these will typically be named "parse", while
+     * this polymorphic method will always be called parseObject.  Any
+     * parse method that does not take a parse_pos should set status
+     * to an error value when no text in the required format is at the
+     * start position.
+     *
+     * @param source    The string to be parsed into an object.
+     * @param result    Formattable to be set to the parse result.
+     *                  If parse fails, return contents are undefined.
+     * @param parse_pos The position to start parsing at. Upon return
+     *                  this param is set to the position after the
+     *                  last character successfully parsed. If the
+     *                  source is not parsed successfully, this param

+/** 
+ * Concrete class which provides the standard calendar used by most of the world.
+ * 

+ * The standard (Gregorian) calendar has 2 eras, BC and AD.
+ * 

+ * This implementation handles a single discontinuity, which corresponds by default to
+ * the date the Gregorian calendar was originally instituted (October 15, 1582). Not all
+ * countries adopted the Gregorian calendar then, so this cutover date may be changed by
+ * the caller.
+ * 

+ * Prior to the institution of the Gregorian Calendar, New Year's Day was March 25. To
+ * avoid confusion, this Calendar always uses January 1. A manual adjustment may be made
+ * if desired for dates that are prior to the Gregorian changeover and which fall
+ * between January 1 and March 24.
+ *
+ * 
Values calculated for the WEEK_OF_YEAR field range from 1 to
+ * 53.  Week 1 for a year is the first week that contains at least
+ * getMinimalDaysInFirstWeek() days from that year.  It thus
+ * depends on the values of getMinimalDaysInFirstWeek(),
+ * getFirstDayOfWeek(), and the day of the week of January 1.
+ * Weeks between week 1 of one year and week 1 of the following year are
+ * numbered sequentially from 2 to 52 or 53 (as needed).
+ *
+ * 
For example, January 1, 1998 was a Thursday.  If
+ * getFirstDayOfWeek() is MONDAY and
+ * getMinimalDaysInFirstWeek() is 4 (these are the values
+ * reflecting ISO 8601 and many national standards), then week 1 of 1998 starts
+ * on December 29, 1997, and ends on January 4, 1998.  If, however,
+ * getFirstDayOfWeek() is SUNDAY, then week 1 of 1998
+ * starts on January 4, 1998, and ends on January 10, 1998; the first three days
+ * of 1998 then are part of week 53 of 1997.
+ *
+ * 
Example for using GregorianCalendar:
+ * 
+ * \code
+ *     // get the supported ids for GMT-08:00 (Pacific Standard Time)
+ *     UErrorCode success = U_ZERO_ERROR;
+ *     const StringEnumeration *ids = TimeZone::createEnumeration(-8 * 60 * 60 * 1000, success);
+ *     // if no ids were returned, something is wrong. get out.
+ *     if (U_FAILURE(success)) {
+ *         return;
+ *     }
+ *
+ *     // begin output
+ *     cout << "Current Time" << endl;
+ *
+ *     // create a Pacific Standard Time time zone
+ *     SimpleTimeZone* pdt = new SimpleTimeZone(-8 * 60 * 60 * 1000, ids->unext(nullptr, success)));
+ *
+ *     // set up rules for daylight savings time
+ *     pdt->setStartRule(UCAL_MARCH, 1, UCAL_SUNDAY, 2 * 60 * 60 * 1000);
+ *     pdt->setEndRule(UCAL_NOVEMBER, 2, UCAL_SUNDAY, 2 * 60 * 60 * 1000);
+ *
+ *     // create a GregorianCalendar with the Pacific Daylight time zone
+ *     // and the current date and time

+ * 
C API: ICU Plugin API

+ *
+ * 
C API allowing run-time loadable modules that extend or modify ICU functionality.

+ *
+ * 
Loading and Configuration

+ *
+ * 
At ICU startup time, the environment variable "ICU_PLUGINS" will be 
+ * queried for a directory name.  If it is not set, the preprocessor symbol 
+ * "DEFAULT_ICU_PLUGINS" will be checked for a default value.

+ *
+ * 
Within the above-named directory, the file  "icuplugins##.txt" will be 
+ * opened, if present, where ## is the major+minor number of the currently 
+ * running ICU (such as, 44 for ICU 4.4, thus icuplugins44.txt)

+ *
+ * 
The configuration file has this format:

+ *
+ * 
    
+ * 
  • Hash (#) begins a comment line
    • 
+ * 
+ * 
  • Non-comment lines have two or three components:
+ * LIBRARYNAME     ENTRYPOINT     [ CONFIGURATION .. ]
    • 
+ *
+ * 
  • Tabs or spaces separate the three items.
    • 
+ *
+ * 
  • LIBRARYNAME is the name of a shared library, either a short name if 
+ * it is on the loader path,  or a full pathname.
    • 
+ *
+ * 
  • ENTRYPOINT is the short (undecorated) symbol name of the plugin's 
+ * entrypoint, as above.
    • 
+ *
+ * 
  • CONFIGURATION is the entire rest of the line . It's passed as-is to 
+ * the plugin.
    • 
+ * 

+ *
+ * 
An example configuration file is, in its entirety:

+ *
+ * \code
+ * # this is icuplugins44.txt
+ * testplug.dll    myPlugin        hello=world
+ * \endcode
+ * 
Plugins are categorized as "high" or "low" level.  Low level are those 
+ * which must be run BEFORE high level plugins, and before any operations 
+ * which cause ICU to be 'initialized'.  If a plugin is low level but 
+ * causes ICU to allocate memory or become initialized, that plugin is said 
+ * to cause a 'level change'. 

+ *
+ * 
At load time, ICU first queries all plugins to determine their level, 
+ * then loads all 'low' plugins first, and then loads all 'high' plugins.  
+ * Plugins are otherwise loaded in the order listed in the configuration file.

+ * 
+ * 
Implementing a Plugin

+ * \code
+ * U_CAPI UPlugTokenReturn U_EXPORT2 
+ * myPlugin (UPlugData *plug, UPlugReason reason, UErrorCode *status) {
+ *   if(reason==UPLUG_REASON_QUERY) {
+ *      uplug_setPlugName(plug, "Simple Plugin");
+ *      uplug_setPlugLevel(plug, UPLUG_LEVEL_HIGH);
+ *    } else if(reason==UPLUG_REASON_LOAD) {
+ *       ... Set up some ICU things here.... 
+ *    } else if(reason==UPLUG_REASON_UNLOAD) {
+ *       ... unload, clean up ...
+ *    }
+ *   return UPLUG_TOKEN;
+ *  }
+ * \endcode
+ *
+ * 
The UPlugData*  is an opaque pointer to the plugin-specific data, and is 
+ * used in all other API calls.

+ *
+ * 
The API contract is:

+ * 
  1. The plugin MUST always return UPLUG_TOKEN as a return value- to 
+ * indicate that it is a valid plugin.
    2. 
+ *
+ * 
  2. When the 'reason' parameter is set to UPLUG_REASON_QUERY,  the 
+ * plugin MUST call uplug_setPlugLevel() to indicate whether it is a high 
+ * level or low level plugin.
    3. 
+ *
+ * 
  3. When the 'reason' parameter is UPLUG_REASON_QUERY, the plugin 
+ * SHOULD call uplug_setPlugName to indicate a human readable plugin name.

+ * Immutable class that picks the best match between a user's desired locales and

Example:

+ * Locale *bestSupported = matcher.getBestLocale(Locale.US, errorCode);  // "en"

+ * 
A matcher takes into account when languages are close to one another,
+ * such as Danish and Norwegian,
+ * and when regional variants are close, like en-GB and en-AU as opposed to en-US.
+ *
+ * 
If there are multiple supported locales with the same (language, script, region)
+ * likely subtags, then the current implementation returns the first of those locales.
+ * It ignores variant subtags (except for pseudolocale variants) and extensions.
+ * This may change in future versions.
+ *
+ * 
For example, the current implementation does not distinguish between
+ * de, de-DE, de-Latn, de-1901, de-u-co-phonebk.
+ *
+ * 
If you prefer one equivalent locale over another, then provide only the preferred one,
+ * or place it earlier in the list of supported locales.
+ *
+ * 
Otherwise, the order of supported locales may have no effect on the best-match results.
+ * The current implementation compares each desired locale with supported locales
+ * in the following order:
+ * 1. Default locale, if supported;
+ * 2. CLDR "paradigm locales" like en-GB and es-419;
+ * 3. other supported locales.
+ * This may change in future versions.
+ *
+ * 
Often a product will just need one matcher instance, built with the languages
+ * that it supports. However, it may want multiple instances with different
+ * default languages based on additional information, such as the domain.

+/**
+ * A Locale object represents a specific geographical, political,
+ * or cultural region. An operation that requires a Locale to perform
+ * its task is called locale-sensitive and uses the Locale
+ * to tailor information for the user. For example, displaying a number
+ * is a locale-sensitive operation--the number should be formatted
+ * according to the customs/conventions of the user's native country,
+ * region, or culture.
+ *
+ * The Locale class is not suitable for subclassing.
+ *
+ * 

+ * You can create a Locale object using the constructor in
+ * this class:
+ * \htmlonly
\endhtmlonly
+ * 
+ *       Locale( const   char*  language,
+ *               const   char*  country,
+ *               const   char*  variant);
+ * 

+ * \htmlonly
\endhtmlonly
+ * The first argument to the constructors is a valid ISO
+ * Language Code. These codes are the lower-case two-letter
+ * codes as defined by ISO-639.
+ * You can find a full list of these codes at:
+ * 

+ * http://www.loc.gov/standards/iso639-2/
+ *
+ * 

+ * The second argument to the constructors is a valid ISO Country
+ * Code. These codes are the upper-case two-letter codes
+ * as defined by ISO-3166.
+ * You can find a full list of these codes at a number of sites, such as:
+ * 

+ * http://www.iso.org/iso/en/prods-services/iso3166ma/index.html
+ *
+ * 

+ * The third constructor requires a third argument--the Variant.
+ * The Variant codes are vendor and browser-specific.
+ * For example, use REVISED for a language's revised script orthography, and POSIX for POSIX.
+ * Where there are two variants, separate them with an underscore, and
+ * put the most important one first. For
+ * example, a Traditional Spanish collation might be referenced, with
+ * "ES", "ES", "Traditional_POSIX".
+ *
+ * 

+ * Because a Locale object is just an identifier for a region,
+ * no validity check is performed when you construct a Locale.
+ * If you want to see whether particular resources are available for the
+ * Locale you construct, you must query those resources. For
+ * example, ask the NumberFormat for the locales it supports
+ * using its getAvailableLocales method.
+ * 
Note: When you ask for a resource for a particular
+ * locale, you get back the best available match, not necessarily
+ * precisely what you asked for. For more information, look at
+ * ResourceBundle.
+ *
+ * 

+ * The Locale class provides a number of convenient constants
+ * that you can use to create Locale objects for commonly used
+ * locales. For example, the following refers to a Locale object
+ * for the United States:
+ * \htmlonly
\endhtmlonly
+ * 
+ *       Locale::getUS()
+ * 

+ * \htmlonly
\endhtmlonly
+ *
+ * 

+ * Once you've created a Locale you can query it for information about
+ * itself. Use getCountry to get the ISO Country Code and
+ * getLanguage to get the ISO Language Code. You can
+ * use getDisplayCountry to get the
+ * name of the country suitable for displaying to the user. Similarly,
+ * you can use getDisplayLanguage to get the name of
+ * the language suitable for displaying to the user. Interestingly,
+ * the getDisplayXXX methods are themselves locale-sensitive
+ * and have two versions: one that uses the default locale and one
+ * that takes a locale as an argument and displays the name or country in
+ * a language appropriate to that locale.
+ *
+ * 

+ * ICU provides a number of classes that perform locale-sensitive
+ * operations. For example, the NumberFormat class formats
+ * numbers, currency, or percentages in a locale-sensitive manner. Classes
+ * such as NumberFormat have a number of convenience methods
+ * for creating a default object of that type. For example, the
+ * NumberFormat class provides these three convenience methods
+ * for creating a default NumberFormat object:
+ * \htmlonly
\endhtmlonly
+ * 
+ *     UErrorCode success = U_ZERO_ERROR;
+ *     Locale myLocale;
+ *     NumberFormat *nf;
+ *
+ *     nf = NumberFormat::createInstance( success );          delete nf;
+ *     nf = NumberFormat::createCurrencyInstance( success );  delete nf;
+ *     nf = NumberFormat::createPercentInstance( success );   delete nf;
+ * 

+ * \htmlonly
\endhtmlonly
+ * Each of these methods has two variants; one with an explicit locale
+ * and one without; the latter using the default locale.
+ * \htmlonly
\endhtmlonly
+ * 
+ *     nf = NumberFormat::createInstance( myLocale, success );          delete nf;
+ *     nf = NumberFormat::createCurrencyInstance( myLocale, success );  delete nf;
+ *     nf = NumberFormat::createPercentInstance( myLocale, success );   delete nf;
+ * 

+ * \htmlonly
\endhtmlonly
+ * A Locale is the mechanism for identifying the kind of object
+ * (NumberFormat) that you would like to get. The locale is
+ * just a mechanism for identifying objects,
+ * not a container for the objects themselves.
+ *
+ * 

+ * Each class that performs locale-sensitive operations allows you
+ * to get all the available objects of that type. You can sift
+ * through these objects by language, country, or variant,
+ * and use the display names to present a menu to the user.
+ * For example, you can create a menu of all the collation objects
+ * suitable for a given language. Such classes implement these
+ * three class methods:
+ * \htmlonly
\endhtmlonly
+ * 
+ *       static Locale* getAvailableLocales(int32_t& numLocales)
+ *       static UnicodeString& getDisplayName(const Locale&  objectLocale,
+ *                                            const Locale&  displayLocale,
+ *                                            UnicodeString& displayName)
+ *       static UnicodeString& getDisplayName(const Locale&  objectLocale,
+ *                                            UnicodeString& displayName)

+ * Parses and represents ICU MessageFormat patterns.
+ * Also handles patterns for ChoiceFormat, PluralFormat and SelectFormat.
+ * Used in the implementations of those classes as well as in tools
+ * for message validation, translation and format conversion.
+ * 

+ * The parser handles all syntax relevant for identifying message arguments.
+ * This includes "complex" arguments whose style strings contain
+ * nested MessageFormat pattern substrings.
+ * For "simple" arguments (with no nested MessageFormat pattern substrings),
+ * the argument style is not parsed any further.
+ * 

+ * The parser handles named and numbered message arguments and allows both in one message.
+ * 

+ * Once a pattern has been parsed successfully, iterate through the parsed data
+ * with countParts(), getPart() and related methods.
+ * 

+ * The data logically represents a parse tree, but is stored and accessed
+ * as a list of "parts" for fast and simple parsing and to minimize object allocations.
+ * Arguments and nested messages are best handled via recursion.
+ * For every _START "part", MessagePattern.getLimitPartIndex() efficiently returns
+ * the index of the corresponding _LIMIT "part".
+ * 

+ * List of "parts":
+ * 
+ * message = MSG_START (SKIP_SYNTAX | INSERT_CHAR | REPLACE_NUMBER | argument)* MSG_LIMIT
+ * argument = noneArg | simpleArg | complexArg
+ * complexArg = choiceArg | pluralArg | selectArg
+ *
+ * noneArg = ARG_START.NONE (ARG_NAME | ARG_NUMBER) ARG_LIMIT.NONE
+ * simpleArg = ARG_START.SIMPLE (ARG_NAME | ARG_NUMBER) ARG_TYPE [ARG_STYLE] ARG_LIMIT.SIMPLE
+ * choiceArg = ARG_START.CHOICE (ARG_NAME | ARG_NUMBER) choiceStyle ARG_LIMIT.CHOICE
+ * pluralArg = ARG_START.PLURAL (ARG_NAME | ARG_NUMBER) pluralStyle ARG_LIMIT.PLURAL
+ * selectArg = ARG_START.SELECT (ARG_NAME | ARG_NUMBER) selectStyle ARG_LIMIT.SELECT
+ *
+ * choiceStyle = ((ARG_INT | ARG_DOUBLE) ARG_SELECTOR message)+
+ * pluralStyle = [ARG_INT | ARG_DOUBLE] (ARG_SELECTOR [ARG_INT | ARG_DOUBLE] message)+
+ * selectStyle = (ARG_SELECTOR message)+
+ * 

+ * 
    
+ *   
  • Literal output text is not represented directly by "parts" but accessed
+ *       between parts of a message, from one part's getLimit() to the next part's getIndex().
+ *   
  • ARG_START.CHOICE stands for an ARG_START Part with ArgType CHOICE.
+ *   
  • In the choiceStyle, the ARG_SELECTOR has the '<', the '#' or
+ *       the less-than-or-equal-to sign (U+2264).
+ *   
  • In the pluralStyle, the first, optional numeric Part has the "offset:" value.
+ *       The optional numeric Part between each (ARG_SELECTOR, message) pair
+ *       is the value of an explicit-number selector like "=2",
+ *       otherwise the selector is a non-numeric identifier.
+ *   
  • The REPLACE_NUMBER Part can occur only in an immediate sub-message of the pluralStyle.

+/**
+ * 
MessageFormat prepares strings for display to users,
+ * with optional arguments (variables/placeholders).
+ * The arguments can occur in any order, which is necessary for translation
+ * into languages with different grammars.
+ *
+ * 
A MessageFormat is constructed from a pattern string
+ * with arguments in {curly braces} which will be replaced by formatted values.
+ *
+ * 
MessageFormat differs from the other Format
+ * classes in that you create a MessageFormat object with one
+ * of its constructors (not with a createInstance style factory
+ * method). Factory methods aren't necessary because MessageFormat
+ * itself doesn't implement locale-specific behavior. Any locale-specific
+ * behavior is defined by the pattern that you provide and the
+ * subformats used for inserted arguments.
+ *
+ * 
Arguments can be named (using identifiers) or numbered (using small ASCII-digit integers).
+ * Some of the API methods work only with argument numbers and throw an exception
+ * if the pattern has named arguments (see {@link #usesNamedArguments()}).
+ *
+ * 
An argument might not specify any format type. In this case,
+ * a numeric value is formatted with a default (for the locale) NumberFormat,
+ * and a date/time value is formatted with a default (for the locale) DateFormat.
+ *
+ * 
An argument might specify a "simple" type for which the specified
+ * Format object is created, cached and used.
+ *
+ * 
An argument might have a "complex" type with nested MessageFormat sub-patterns.
+ * During formatting, one of these sub-messages is selected according to the argument value
+ * and recursively formatted.
+ *
+ * 
After construction, a custom Format object can be set for
+ * a top-level argument, overriding the default formatting and parsing behavior
+ * for that argument.
+ * However, custom formatting can be achieved more simply by writing
+ * a typeless argument in the pattern string
+ * and supplying it with a preformatted string value.
+ *
+ * 
When formatting, MessageFormat takes a collection of argument values
+ * and writes an output string.
+ * The argument values may be passed as an array
+ * (when the pattern contains only numbered arguments)
+ * or as an array of names and and an array of arguments (which works for both named
+ * and numbered arguments).
+ *
+ * 
Each argument is matched with one of the input values by array index or argument name
+ * and formatted according to its pattern specification
+ * (or using a custom Format object if one was set).
+ * A numbered pattern argument is matched with an argument name that contains that number
+ * as an ASCII-decimal-digit string (without leading zero).
+ *
+ * 
Patterns and Their Interpretation

+ *
+ * MessageFormat uses patterns of the following form:
+ * 
+ * message = messageText (argument messageText)*
+ * argument = noneArg | simpleArg | complexArg
+ * complexArg = choiceArg | pluralArg | selectArg | selectordinalArg
+ *
+ * noneArg = '{' argNameOrNumber '}'
+ * simpleArg = '{' argNameOrNumber ',' argType [',' argStyle] '}'
+ * choiceArg = '{' argNameOrNumber ',' "choice" ',' choiceStyle '}'
+ * pluralArg = '{' argNameOrNumber ',' "plural" ',' pluralStyle '}'
+ * selectArg = '{' argNameOrNumber ',' "select" ',' selectStyle '}'
+ * selectordinalArg = '{' argNameOrNumber ',' "selectordinal" ',' pluralStyle '}'
+ *
+ * choiceStyle: see {@link ChoiceFormat}
+ * pluralStyle: see {@link PluralFormat}
+ * selectStyle: see {@link SelectFormat}
+ *
+ * argNameOrNumber = argName | argNumber
+ * argName = [^[[:Pattern_Syntax:][:Pattern_White_Space:]]]+
+ * argNumber = '0' | ('1'..'9' ('0'..'9')*)
+ *
+ * argType = "number" | "date" | "time" | "spellout" | "ordinal" | "duration"
+ * argStyle = "short" | "medium" | "long" | "full" | "integer" | "currency" | "percent" | argStyleText | "::" argSkeletonText
+ * 

+ *
+ * 
    
+ *   
  • messageText can contain quoted literal strings including syntax characters.
+ *       A quoted literal string begins with an ASCII apostrophe and a syntax character
+ *       (usually a {curly brace}) and continues until the next single apostrophe.
+ *       A double ASCII apostrophe inside or outside of a quoted string represents
+ *       one literal apostrophe.
+ *   
  • Quotable syntax characters are the {curly braces} in all messageText parts,
+ *       plus the '#' sign in a messageText immediately inside a pluralStyle,
+ *       and the '|' symbol in a messageText immediately inside a choiceStyle.
+ *   
  • See also {@link #UMessagePatternApostropheMode}
+ *   
  • In argStyleText, every single ASCII apostrophe begins and ends quoted literal text,
+ *       and unquoted {curly braces} must occur in matched pairs.
+ * 

+ *
+ * 
Recommendation: Use the real apostrophe (single quote) character
+ * \htmlonly’\endhtmlonly (U+2019) for
+ * human-readable text, and use the ASCII apostrophe ' (U+0027)
+ * only in program syntax, like quoting in MessageFormat.
+ * See the annotations for U+0027 Apostrophe in The Unicode Standard.
+ *
+ * 
The choice argument type is deprecated.
+ * Use plural arguments for proper plural selection,
+ * and select arguments for simple selection among a fixed set of choices.
+ *
+ * 
The argType and argStyle values are used to create
+ * a Format instance for the format element. The following
+ * table shows how the values map to Format instances. Combinations not
+ * shown in the table are illegal. Any argStyleText must
+ * be a valid pattern string for the Format subclass used.
+ *

+ * 
Argument formatting

+ *
+ * 
Arguments are formatted according to their type, using the default
+ * ICU formatters for those types, unless otherwise specified.

+ *
+ * 
There are also several ways to control the formatting.

+ *
+ * 
We recommend you use default styles, predefined style values, skeletons,
+ * or preformatted values, but not pattern strings or custom format objects.

+ *
+ * 
For more details, see the
+ * ICU User Guide.

+ *
+ * 
Usage Information

+ *
+ * 
Here are some examples of usage:
+ * Example 1:
+ *
+ * 
+ * \code
+ *     UErrorCode success = U_ZERO_ERROR;
+ *     GregorianCalendar cal(success);
+ *     Formattable arguments[] = {
+ *         7L,
+ *         Formattable( (Date) cal.getTime(success), Formattable::kIsDate),
+ *         "a disturbance in the Force"
+ *     };
+ *
+ *     UnicodeString result;
+ *     MessageFormat::format(
+ *          "At {1,time,::jmm} on {1,date,::dMMMM}, there was {2} on planet {0,number}.",
+ *          arguments, 3, result, success );
+ *
+ *     cout << "result: " << result << endl;
+ *     //: At 4:34 PM on March 23, there was a disturbance
+ *     //             in the Force on planet 7.
+ * \endcode
+ * 

+ *
+ * Typically, the message format will come from resources, and the
+ * arguments will be dynamically set at runtime.
+ *
+ * 
Example 2:
+ *
+ * 
+ *  \code
+ *     success = U_ZERO_ERROR;
+ *     Formattable testArgs[] = {3L, "MyDisk"};
+ *
+ *     MessageFormat form(
+ *         "The disk \"{1}\" contains {0} file(s).", success );
+ *
+ *     UnicodeString string;
+ *     FieldPosition fpos = 0;
+ *     cout << "format: " << form.format(testArgs, 2, string, fpos, success ) << endl;
+ *
+ *     // output, with different testArgs:
+ *     // output: The disk "MyDisk" contains 0 file(s).
+ *     // output: The disk "MyDisk" contains 1 file(s).
+ *     // output: The disk "MyDisk" contains 1,273 file(s).
+ *  \endcode
+ *  

+ *
+ *
+ * 
For messages that include plural forms, you can use a plural argument:
+ * 
+ * \code
+ *  success = U_ZERO_ERROR;
+ *  MessageFormat msgFmt(
+ *       "{num_files, plural, "
+ *       "=0{There are no files on disk \"{disk_name}\".}"
+ *       "=1{There is one file on disk \"{disk_name}\".}"
+ *       "other{There are # files on disk \"{disk_name}\".}}",
+ *      Locale("en"),
+ *      success);
+ *  FieldPosition fpos = 0;
+ *  Formattable testArgs[] = {0L, "MyDisk"};
+ *  UnicodeString testArgsNames[] = {"num_files", "disk_name"};
+ *  UnicodeString result;
+ *  cout << msgFmt.format(testArgs, testArgsNames, 2, result, fpos, 0, success);
+ *  testArgs[0] = 3L;
+ *  cout << msgFmt.format(testArgs, testArgsNames, 2, result, fpos, 0, success);
+ * \endcode
+ * output:
+ * There are no files on disk "MyDisk".
+ * There are 3 files on "MyDisk".
+ * 

+ * See {@link PluralFormat} and {@link PluralRules} for details.
+ *
+ * 
Synchronization

+ *
+ * 
MessageFormats are not synchronized.
+ * It is recommended to create separate format instances for each thread.
+ * If multiple threads access a format concurrently, it must be synchronized
+ * externally.

+/**
+ * Unicode normalization functionality for standard Unicode normalization or
+ * for using custom mapping tables.
+ * All instances of this class are unmodifiable/immutable.
+ * Instances returned by getInstance() are singletons that must not be deleted by the caller.
+ * The Normalizer2 class is not intended for public subclassing.
+ *
+ * The primary functions are to produce a normalized string and to detect whether
+ * a string is already normalized.
+ * The most commonly used normalization forms are those defined in
+ * http://www.unicode.org/unicode/reports/tr15/
+ * However, this API supports additional normalization forms for specialized purposes.
+ * For example, NFKC_Casefold is provided via getInstance("nfkc_cf", COMPOSE)
+ * and can be used in implementations of UTS #46.
+ *
+ * Not only are the standard compose and decompose modes supplied,
+ * but additional modes are provided as documented in the Mode enum.
+ *
+ * Some of the functions in this class identify normalization boundaries.
+ * At a normalization boundary, the portions of the string
+ * before it and starting from it do not interact and can be handled independently.
+ *
+ * The spanQuickCheckYes() stops at a normalization boundary.
+ * When the goal is a normalized string, then the text before the boundary
+ * can be copied, and the remainder can be processed with normalizeSecondAndAppend().
+ *
+ * The hasBoundaryBefore(), hasBoundaryAfter() and isInert() functions test whether
+ * a character is guaranteed to be at a normalization boundary,
+ * regardless of context.
+ * This is used for moving from one normalization boundary to the next
+ * or preceding boundary, and for performing iterative normalization.
+ *
+ * Iterative normalization is useful when only a small portion of a
+ * longer string needs to be processed.
+ * For example, in ICU, iterative normalization is used by the NormalizationTransliterator
+ * (to avoid replacing already-normalized text) and ucol_nextSortKeyPart()
+ * (to process only the substring for which sort key bytes are computed).
+ *
+ * The set of normalization boundaries returned by these functions may not be
+ * complete: There may be more boundaries that could be returned.
+ * Different functions may return different boundaries.

+/**
+ * Old Unicode normalization API.
+ *
+ * This API has been replaced by the Normalizer2 class and is only available
+ * for backward compatibility. This class simply delegates to the Normalizer2 class.
+ * There is one exception: The new API does not provide a replacement for Normalizer::compare().
+ *
+ * The Normalizer class supports the standard normalization forms described in
+ * 
+ * Unicode Standard Annex #15: Unicode Normalization Forms.
+ *
+ * The Normalizer class consists of two parts:
+ * - static functions that normalize strings or test if strings are normalized
+ * - a Normalizer object is an iterator that takes any kind of text and
+ *   provides iteration over its normalized form
+ *
+ * The Normalizer class is not suitable for subclassing.
+ *
+ * For basic information about normalization forms and details about the C API
+ * please see the documentation in unorm.h.
+ *
+ * The iterator API with the Normalizer constructors and the non-static functions
+ * use a CharacterIterator as input. It is possible to pass a string which
+ * is then internally wrapped in a CharacterIterator.
+ * The input text is not normalized all at once, but incrementally where needed
+ * (providing efficient random access).
+ * This allows to pass in a large text but spend only a small amount of time
+ * normalizing a small part of that text.
+ * However, if the entire text is normalized, then the iterator will be
+ * slower than normalizing the entire text at once and iterating over the result.
+ * A possible use of the Normalizer iterator is also to report an index into the
+ * original text that is close to where the normalized characters come from.
+ *
+ * Important: The iterator API was cleaned up significantly for ICU 2.0.
+ * The earlier implementation reported the getIndex() inconsistently,
+ * and previous() could not be used after setIndex(), next(), first(), and current().
+ *
+ * Normalizer allows to start normalizing from anywhere in the input text by
+ * calling setIndexOnly(), first(), or last().
+ * Without calling any of these, the iterator will start at the beginning of the text.
+ *
+ * At any time, next() returns the next normalized code point (UChar32),
+ * with post-increment semantics (like CharacterIterator::next32PostInc()).
+ * previous() returns the previous normalized code point (UChar32),
+ * with pre-decrement semantics (like CharacterIterator::previous32()).
+ *
+ * current() returns the current code point
+ * (respectively the one at the newly set index) without moving
+ * the getIndex(). Note that if the text at the current position
+ * needs to be normalized, then these functions will do that.
+ * (This is why current() is not const.)
+ * It is more efficient to call setIndexOnly() instead, which does not
+ * normalize.
+ *
+ * getIndex() always refers to the position in the input text where the normalized
+ * code points are returned from. It does not always change with each returned
+ * code point.
+ * The code point that is returned from any of the functions
+ * corresponds to text at or after getIndex(), according to the
+ * function's iteration semantics (post-increment or pre-decrement).
+ *
+ * next() returns a code point from at or after the getIndex()
+ * from before the next() call. After the next() call, the getIndex()
+ * might have moved to where the next code point will be returned from
+ * (from a next() or current() call).
+ * This is semantically equivalent to array access with array[index++]
+ * (post-increment semantics).
+ *
+ * previous() returns a code point from at or after the getIndex()
+ * from after the previous() call.
+ * This is semantically equivalent to array access with array[--index]
+ * (pre-decrement semantics).
+ *
+ * Internally, the Normalizer iterator normalizes a small piece of text
+ * starting at the getIndex() and ending at a following "safe" index.
+ * The normalized results is stored in an internal string buffer, and
+ * the code points are iterated from there.
+ * With multiple iteration calls, this is repeated until the next piece
+ * of text needs to be normalized, and the getIndex() needs to be moved.
+ *
+ * The following "safe" index, the internal buffer, and the secondary
+ * iteration index into that buffer are not exposed on the API.
+ * This also means that it is currently not practical to return to
+ * a particular, arbitrary position in the text because one would need to
+ * know, and be able to set, in addition to the getIndex(), at least also the
+ * current index into the internal buffer.
+ * It is currently only possible to observe when getIndex() changes
+ * (with careful consideration of the iteration semantics),
+ * at which time the internal index will be 0.
+ * For example, if getIndex() is different after next() than before it,
+ * then the internal index is 0 and one can return to this getIndex()
+ * later with setIndexOnly().
+ *
+ * Note: While the setIndex() and getIndex() refer to indices in the
+ * underlying Unicode input text, the next() and previous() methods
+ * iterate through characters in the normalized output.
+ * This means that there is not necessarily a one-to-one correspondence
+ * between characters returned by next() and previous() and the indices
+ * passed to and returned from setIndex() and getIndex().
+ * It is for this reason that Normalizer does not implement the CharacterIterator interface.

+ *
+ * 
+ * // Most basic usage:
+ * NumberFormatter::withLocale(...).format(123).toString();  // 1,234 in en-US
+ *
+ * // Custom notation, unit, and rounding precision:
+ * NumberFormatter::with()
+ *     .notation(Notation::compactShort())
+ *     .unit(CurrencyUnit("EUR", status))
+ *     .precision(Precision::maxDigits(2))
+ *     .locale(...)
+ *     .format(1234)
+ *     .toString();  // €1.2K in en-US
+ *
+ * // Create a formatter in a singleton by value for use later:
+ * static const LocalizedNumberFormatter formatter = NumberFormatter::withLocale(...)
+ *     .unit(NoUnit::percent())
+ *     .precision(Precision::fixedFraction(3));
+ * formatter.format(5.9831).toString();  // 5.983% in en-US
+ *
+ * // Create a "template" in a singleton unique_ptr but without setting a locale until the call site:
+ * std::unique_ptr template = NumberFormatter::with()
+ *     .sign(UNumberSignDisplay::UNUM_SIGN_ALWAYS)
+ *     .unit(MeasureUnit::getMeter())
+ *     .unitWidth(UNumberUnitWidth::UNUM_UNIT_WIDTH_FULL_NAME)
+ *     .clone();
+ * template->locale(...).format(1234).toString();  // +1,234 meters in en-US
+ * 

+ *
+ * 

+ * This API offers more features than DecimalFormat and is geared toward new users of ICU.
+ *
+ * 

+ * NumberFormatter instances (i.e., LocalizedNumberFormatter and UnlocalizedNumberFormatter)
+ * are immutable and thread safe. This means that invoking a configuration method has no
+ * effect on the receiving instance; you must store and use the new number formatter instance it returns instead.
+ *
+ * 
+ * UnlocalizedNumberFormatter formatter = UnlocalizedNumberFormatter::with().notation(Notation::scientific());
+ * formatter.precision(Precision.maxFraction(2)); // does nothing!
+ * formatter.locale(Locale.getEnglish()).format(9.8765).toString(); // prints "9.8765E0", not "9.88E0"
+ * 

+ *
+ * 

+ * This API is based on the fluent design pattern popularized by libraries such as Google's Guava. For
+ * extensive details on the design of this API, read the design doc.

+/**
+ * \file
+ * \brief C++ API: Library for localized formatting of number, currency, and unit ranges.
+ *
+ * The main entrypoint to the formatting of ranges of numbers, including currencies and other units of measurement.
+ * 

+ * Usage example:
+ * 

+ * 
+ * NumberRangeFormatter::with()
+ *     .identityFallback(UNUM_IDENTITY_FALLBACK_APPROXIMATELY_OR_SINGLE_VALUE)
+ *     .numberFormatterFirst(NumberFormatter::with().adoptUnit(MeasureUnit::createMeter()))
+ *     .numberFormatterSecond(NumberFormatter::with().adoptUnit(MeasureUnit::createKilometer()))
+ *     .locale("en-GB")
+ *     .formatFormattableRange(750, 1.2, status)
+ *     .toString(status);
+ * // => "750 m - 1.2 km"
+ * 

+ * 

+ * Like NumberFormatter, NumberRangeFormatter instances (i.e., LocalizedNumberRangeFormatter
+ * and UnlocalizedNumberRangeFormatter) are immutable and thread-safe. This API is based on the
+ * fluent design pattern popularized by libraries such as Google's Guava.

+/**
+ * 
IMPORTANT: New users are strongly encouraged to see if
+ * numberformatter.h fits their use case.  Although not deprecated, this header
+ * is provided for backwards compatibility only.
+ *
+ * Abstract base class for all number formats.  Provides interface for
+ * formatting and parsing a number.  Also provides methods for
+ * determining which locales have number formats, and what their names
+ * are.
+ *
+ * \headerfile unicode/numfmt.h "unicode/numfmt.h"
+ * 

+ * NumberFormat helps you to format and parse numbers for any locale.
+ * Your code can be completely independent of the locale conventions
+ * for decimal points, thousands-separators, or even the particular
+ * decimal digits used, or whether the number format is even decimal.
+ * 

+ * To format a number for the current Locale, use one of the static
+ * factory methods:
+ * \code
+ *    #include 
+ *    #include "unicode/numfmt.h"
+ *    #include "unicode/unistr.h"
+ *    #include "unicode/ustream.h"
+ *    using namespace std;
+ *    
+ *    int main() {
+ *        double myNumber = 7.0;
+ *        UnicodeString myString;
+ *        UErrorCode success = U_ZERO_ERROR;
+ *        NumberFormat* nf = NumberFormat::createInstance(success);
+ *        nf->format(myNumber, myString);
+ *        cout << " Example 1: " << myString << endl;
+ *    }
+ * \endcode
+ * Note that there are additional factory methods within subclasses of
+ * NumberFormat.
+ * 

+ * If you are formatting multiple numbers, it is more efficient to get
+ * the format and use it multiple times so that the system doesn't
+ * have to fetch the information about the local language and country
+ * conventions multiple times.
+ * \code
+ *     UnicodeString myString;
+ *     UErrorCode success = U_ZERO_ERROR;
+ *     NumberFormat *nf = NumberFormat::createInstance( success );
+ *     for (int32_t number: {123, 3333, -1234567}) {
+ *         nf->format(number, myString);
+ *         myString += "; ";
+ *     }
+ *     cout << " Example 2: " << myString << endl;
+ * \endcode
+ * To format a number for a different Locale, specify it in the
+ * call to \c createInstance().
+ * \code
+ *     nf = NumberFormat::createInstance(Locale::getFrench(), success);
+ * \endcode
+ * You can use a \c NumberFormat to parse also.
+ * \code
+ *    UErrorCode success;
+ *    Formattable result(-999);  // initialized with error code
+ *    nf->parse(myString, result, success);
+ * \endcode
+ * Use \c createInstance() to get the normal number format for a \c Locale.
+ * There are other static factory methods available.  Use \c createCurrencyInstance()
+ * to get the currency number format for that country.  Use \c createPercentInstance()
+ * to get a format for displaying percentages. With this format, a
+ * fraction from 0.53 is displayed as 53%.
+ * 

+ * The type of number formatting can be specified by passing a 'style' parameter to \c createInstance().
+ * For example, use\n
+ * \c createInstance(locale, UNUM_DECIMAL, errorCode) to get the normal number format,\n
+ * \c createInstance(locale, UNUM_PERCENT, errorCode) to get a format for displaying percentage,\n
+ * \c createInstance(locale, UNUM_SCIENTIFIC, errorCode) to get a format for displaying scientific number,\n
+ * \c createInstance(locale, UNUM_CURRENCY, errorCode) to get the currency number format,
+ * in which the currency is represented by its symbol, for example, "$3.00".\n
+ * \c createInstance(locale, UNUM_CURRENCY_ISO, errorCode)  to get the currency number format,
+ * in which the currency is represented by its ISO code, for example "USD3.00".\n
+ * \c createInstance(locale, UNUM_CURRENCY_PLURAL, errorCode) to get the currency number format,
+ * in which the currency is represented by its full name in plural format,
+ * for example, "3.00 US dollars" or "1.00 US dollar".
+ * 

+ * You can also control the display of numbers with such methods as
+ * \c getMinimumFractionDigits().  If you want even more control over the
+ * format or parsing, or want to give your users more control, you can
+ * try dynamic_casting the \c NumberFormat you get from the factory methods to a
+ * \c DecimalFormat. This will work for the vast majority of
+ * countries; just remember to test for nullptr in case you
+ * encounter an unusual one.
+ * 

+ * You can also use forms of the parse and format methods with
+ * \c ParsePosition and \c FieldPosition to allow you to:
+ * 
    
+ *   
  • (a) progressively parse through pieces of a string.
+ *   
  • (b) align the decimal point and other areas.
+ * 

+ * For example, you can align numbers in two ways.
+ * 

+ * If you are using a monospaced font with spacing for alignment, you
+ * can pass the \c FieldPosition in your format call, with field =
+ * \c UNUM_INTEGER_FIELD. On output, \c getEndIndex will be set to the offset
+ * between the last character of the integer and the decimal. Add
+ * (desiredSpaceCount - getEndIndex) spaces at the front of the
+ * string.
+ * 

+ * If you are using proportional fonts, instead of padding with
+ * spaces, measure the width of the string in pixels from the start to
+ * getEndIndex.  Then move the pen by (desiredPixelWidth -
+ * widthToAlignmentPoint) before drawing the text.  It also works
+ * where there is no decimal, but possibly additional characters at
+ * the end, e.g. with parentheses in negative numbers: "(12)" for -12.
+ * 

+ * User subclasses are not supported. While clients may write
+ * subclasses, such code will not necessarily work and will not be
+ * guaranteed to work stably from release to release.

+ * \brief Basic types for the platform.
+ *
+ * This file used to be generated by autoconf/configure.
+ * Starting with ICU 49, platform.h is a normal source file,
+ * to simplify cross-compiling and working with non-autoconf/make build systems.
+ *
+ * When a value in this file does not work on a platform, then please
+ * try to derive it from the U_PLATFORM value
+ * (for which we might need a new value constant in rare cases)
+ * and/or from other macros that are predefined by the compiler
+ * or defined in standard (POSIX or platform or compiler) headers.
+ *
+ * As a temporary workaround, you can add an explicit \#define for some macros
+ * before it is first tested, or add an equivalent -D macro definition
+ * to the compiler's command line.
+ *
+ * Note: Some compilers provide ways to show the predefined macros.
+ * For example, with gcc you can compile an empty .c file and have the compiler
+ * print the predefined macros with
+ * \code
+ * gcc -E -dM -x c /dev/null | sort
+ * \endcode
+ * (You can provide an actual empty .c file rather than /dev/null.
+ * -x c++ is for C++.)

+ * and hard to deal with variants of platforms.

+ * AT&T and Sun collaborated on a project to merge the most popular Unix variants
+ * on the market at that time: BSD, System V, and Xenix.

+ * 
These definitions allow to specify the encoding of text

+ * It is enough to determine the code point values of "invariant characters",
+ * which are the ones shared by all encodings that are in use
+ * on a given platform.

+ *
+ * 
Those "invariant characters" should be all the uppercase and lowercase
+ * latin letters, the digits, the space, and "basic punctuation".
+ * Also, '\\n', '\\r', '\\t' should be available.

+ *
+ * 
The list of "invariant characters" is:

+ * \code
+ *    A-Z  a-z  0-9  SPACE  "  %  &  '  (  )  *  +  ,  -  .  /  :  ;  <  =  >  ?  _
+ * \endcode
+ *

+ *
+ * 
This matches the IBM Syntactic Character Set (CS 640).

+ *
+ * 
In other words, all the graphic characters in 7-bit ASCII should
+ * be safely accessible except the following:

+ *    '\'

+/**
+ * 

+ * PluralFormat supports the creation of internationalized
+ * messages with plural inflection. It is based on plural
+ * selection, i.e. the caller specifies messages for each
+ * plural case that can appear in the user's language and the
+ * PluralFormat selects the appropriate message based on
+ * the number.
+ * 

+ * 
The Problem of Plural Forms in Internationalized Messages

+ * 

+ * Different languages have different ways to inflect
+ * plurals. Creating internationalized messages that include plural
+ * forms is only feasible when the framework is able to handle plural
+ * forms of all languages correctly. ChoiceFormat
+ * doesn't handle this well, because it attaches a number interval to
+ * each message and selects the message whose interval contains a
+ * given number. This can only handle a finite number of
+ * intervals. But in some languages, like Polish, one plural case
+ * applies to infinitely many intervals (e.g., the plural case applies to
+ * numbers ending with 2, 3, or 4 except those ending with 12, 13, or
+ * 14). Thus ChoiceFormat is not adequate.
+ * 

+ * PluralFormat deals with this by breaking the problem
+ * into two parts:
+ * 
    
+ * 
  • It uses PluralRules that can define more complex
+ *     conditions for a plural case than just a single interval. These plural
+ *     rules define both what plural cases exist in a language, and to
+ *     which numbers these cases apply.
+ * 
  • It provides predefined plural rules for many languages. Thus, the programmer
+ *     need not worry about the plural cases of a language and
+ *     does not have to define the plural cases; they can simply
+ *     use the predefined keywords. The whole plural formatting of messages can
+ *     be done using localized patterns from resource bundles. For predefined plural
+ *     rules, see the CLDR Language Plural Rules page at
+ *     https://unicode-org.github.io/cldr-staging/charts/latest/supplemental/language_plural_rules.html
+ * 

+ * 

+ * 
Usage of PluralFormat

+ * 
Note: Typically, plural formatting is done via MessageFormat
+ * with a plural argument type,
+ * rather than using a stand-alone PluralFormat.
+ * 

+ * This discussion assumes that you use PluralFormat with
+ * a predefined set of plural rules. You can create one using one of
+ * the constructors that takes a locale object. To
+ * specify the message pattern, you can either pass it to the
+ * constructor or set it explicitly using the
+ * applyPattern() method. The format()
+ * method takes a number object and selects the message of the
+ * matching plural case. This message will be returned.
+ * 

+ * 
Patterns and Their Interpretation

+ * 

+ * The pattern text defines the message output for each plural case of the
+ * specified locale. Syntax:
+ * 
+ * pluralStyle = [offsetValue] (selector '{' message '}')+
+ * offsetValue = "offset:" number
+ * selector = explicitValue | keyword
+ * explicitValue = '=' number  // adjacent, no white space in between
+ * keyword = [^[[:Pattern_Syntax:][:Pattern_White_Space:]]]+
+ * message: see {@link MessageFormat}
+ * 

+ * Pattern_White_Space between syntax elements is ignored, except
+ * between the {curly braces} and their sub-message,
+ * and between the '=' and the number of an explicitValue.
+ *
+ * 

+ * There are 6 predefined casekeyword in CLDR/ICU - 'zero', 'one', 'two', 'few', 'many' and
+ * 'other'. You always have to define a message text for the default plural case
+ * other which is contained in every rule set.
+ * If you do not specify a message text for a particular plural case, the
+ * message text of the plural case other gets assigned to this
+ * plural case.
+ * 

+ * When formatting, the input number is first matched against the explicitValue clauses.
+ * If there is no exact-number match, then a keyword is selected by calling
+ * the PluralRules with the input number minus the offset.
+ * (The offset defaults to 0 if it is omitted from the pattern string.)
+ * If there is no clause with that keyword, then the "other" clauses is returned.
+ * 

+ * An unquoted pound sign (#) in the selected sub-message
+ * itself (i.e., outside of arguments nested in the sub-message)
+ * is replaced by the input number minus the offset.
+ * The number-minus-offset value is formatted using a
+ * NumberFormat for the PluralFormat's locale. If you
+ * need special number formatting, you have to use a MessageFormat
+ * and explicitly specify a NumberFormat argument.
+ * Note: That argument is formatting without subtracting the offset!
+ * If you need a custom format and have a non-zero offset, then you need to pass the
+ * number-minus-offset value as a separate parameter.
+ * 

+ * For a usage example, see the {@link MessageFormat} class documentation.
+ *
+ * 
Defining Custom Plural Rules

+ * 
If you need to use PluralFormat with custom rules, you can
+ * create a PluralRules object and pass it to
+ * PluralFormat's constructor. If you also specify a locale in this
+ * constructor, this locale will be used to format the number in the message
+ * texts.
+ * 

+ * For more information about PluralRules, see
+ * {@link PluralRules}.

+/**
+ * Defines rules for mapping non-negative numeric values onto a small set of
+ * keywords. Rules are constructed from a text description, consisting
+ * of a series of keywords and conditions.  The {@link #select} method
+ * examines each condition in order and returns the keyword for the
+ * first condition that matches the number.  If none match,
+ * default rule(other) is returned.
+ *
+ * For more information, details, and tips for writing rules, see the
+ * LDML spec, Part 3.5 Language Plural Rules:
+ * https://www.unicode.org/reports/tr35/tr35-numbers.html#Language_Plural_Rules
+ *
+ * Examples:
+ *   "one: n is 1; few: n in 2..4"

+ *  This defines two rules, for 'one' and 'few'.  The condition for
+ *  'one' is "n is 1" which means that the number must be equal to
+ *  1 for this condition to pass.  The condition for 'few' is
+ *  "n in 2..4" which means that the number must be between 2 and
+ *  4 inclusive for this condition to pass.  All other numbers
+ *  are assigned the keyword "other" by the default rule.
+ *  
+ *    "zero: n is 0; one: n is 1; zero: n mod 100 in 1..19"

+ *  This illustrates that the same keyword can be defined multiple times.
+ *  Each rule is examined in order, and the first keyword whose condition
+ *  passes is the one returned.  Also notes that a modulus is applied
+ *  to n in the last rule.  Thus its condition holds for 119, 219, 319...
+ *  
+ *    "one: n is 1; few: n mod 10 in 2..4 and n mod 100 not in 12..14"

+ *  This illustrates conjunction and negation.  The condition for 'few'
+ *  has two parts, both of which must be met: "n mod 10 in 2..4" and
+ *  "n mod 100 not in 12..14".  The first part applies a modulus to n
+ *  before the test as in the previous example.  The second part applies
+ *  a different modulus and also uses negation, thus it matches all
+ *  numbers _not_ in 12, 13, 14, 112, 113, 114, 212, 213, 214...
+ *  

+ *  

+ * Syntax:
+ * \code
+ * rules         = rule (';' rule)*
+ * rule          = keyword ':' condition
+ * keyword       = 
+ * condition     = and_condition ('or' and_condition)*
+ * and_condition = relation ('and' relation)*
+ * relation      = is_relation | in_relation | within_relation | 'n' 
+ * is_relation   = expr 'is' ('not')? value
+ * in_relation   = expr ('not')? 'in' range_list
+ * within_relation = expr ('not')? 'within' range
+ * expr          = ('n' | 'i' | 'f' | 'v' | 'j') ('mod' value)?
+ * range_list    = (range | value) (',' range_list)*
+ * value         = digit+  ('.' digit+)?
+ * digit         = 0|1|2|3|4|5|6|7|8|9
+ * range         = value'..'value
+ * \endcode
+ * 

+ * 

+ * 

+ * The i, f, and v values are defined as follows:
+ * 

+ * 
    
+ * 
  • i to be the integer digits.
    • 
+ * 
  • f to be the visible fractional digits, as an integer.
    • 
+ * 
  • v to be the number of visible fraction digits.
    • 
+ * 
  • j is defined to only match integers. That is j is 3 fails if v != 0 (eg for 3.1 or 3.0).
    • 
+ * 

+ * 

+ * Examples are in the following table:
+ *

+ * 

+ * The difference between 'in' and 'within' is that 'in' only includes integers in the specified range, while 'within'
+ * includes all values. Using 'within' with a range_list consisting entirely of values is the same as using 'in' (it's
+ * not an error).
+ * 

+
+ * An "identifier" is a sequence of characters that do not have the
+ * Unicode Pattern_Syntax or Pattern_White_Space properties.
+ * 

+ * The difference between 'in' and 'within' is that 'in' only includes
+ * integers in the specified range, while 'within' includes all values.
+ * Using 'within' with a range_list consisting entirely of values is the
+ * same as using 'in' (it's not an error).
+ *

+ * 

+ * Keywords
+ * could be defined by users or from ICU locale data. There are 6
+ * predefined values in ICU - 'zero', 'one', 'two', 'few', 'many' and
+ * 'other'. Callers need to check the value of keyword returned by
+ * {@link #select} method.
+ * 

+ *
+ * Examples:
+ * UnicodeString keyword = pl->select(number);
+ * if (keyword== UnicodeString("one") {
+ *     ...
+ * }
+ * else if ( ... )
+ * 

+ * Note:

+ *  

+ *   ICU defines plural rules for many locales based on CLDR Language Plural Rules.
+ *   For these predefined rules, see CLDR page at
+ *   https://unicode-org.github.io/cldr-staging/charts/latest/supplemental/language_plural_rules.html

+/**
+ * The RuleBasedNumberFormat class formats numbers according to a set of rules. This number formatter is
+ * typically used for spelling out numeric values in words (e.g., 25,3476 as
+ * "twenty-five thousand three hundred seventy-six" or "vingt-cinq mille trois
+ * cents soixante-seize" or
+ * "fünfundzwanzigtausenddreihundertsechsundsiebzig"), but can also be used for
+ * other complicated formatting tasks, such as formatting a number of seconds as hours,
+ * minutes and seconds (e.g., 3,730 as "1:02:10").
+ *
+ * 
The resources contain three predefined formatters for each locale: spellout, which
+ * spells out a value in words (123 is "one hundred twenty-three"); ordinal, which
+ * appends an ordinal suffix to the end of a numeral (123 is "123rd"); and
+ * duration, which shows a duration in seconds as hours, minutes, and seconds (123 is
+ * "2:03").  The client can also define more specialized RuleBasedNumberFormats
+ * by supplying programmer-defined rule sets.

+ *
+ * 
The behavior of a RuleBasedNumberFormat is specified by a textual description
+ * that is either passed to the constructor as a String or loaded from a resource
+ * bundle. In its simplest form, the description consists of a semicolon-delimited list of rules.
+ * Each rule has a string of output text and a value or range of values it is applicable to.
+ * In a typical spellout rule set, the first twenty rules are the words for the numbers from
+ * 0 to 19:

+ *
+ * 
zero; one; two; three; four; five; six; seven; eight; nine;
+ * ten; eleven; twelve; thirteen; fourteen; fifteen; sixteen; seventeen; eighteen; nineteen;

+ *
+ * 
For larger numbers, we can use the preceding set of rules to format the ones place, and
+ * we only have to supply the words for the multiples of 10:

+ *
+ * 
 20: twenty[->>];
+ * 30: thirty[->>];
+ * 40: forty[->>];
+ * 50: fifty[->>];
+ * 60: sixty[->>];
+ * 70: seventy[->>];
+ * 80: eighty[->>];
+ * 90: ninety[->>];

+ *
+ * 
In these rules, the base value is spelled out explicitly and set off from the
+ * rule's output text with a colon. The rules are in a sorted list, and a rule is applicable
+ * to all numbers from its own base value to one less than the next rule's base value. The
+ * ">>" token is called a substitution and tells the formatter to
+ * isolate the number's ones digit, format it using this same set of rules, and place the
+ * result at the position of the ">>" token. Text in brackets is omitted if
+ * the number being formatted is an even multiple of 10 (the hyphen is a literal hyphen; 24
+ * is "twenty-four," not "twenty four").

+ *
+ * 
For even larger numbers, we can actually look up several parts of the number in the
+ * list:

+ *
+ * 
100: << hundred[ >>];

+ *
+ * 
The "<<" represents a new kind of substitution. The << isolates
+ * the hundreds digit (and any digits to its left), formats it using this same rule set, and
+ * places the result where the "<<" was. Notice also that the meaning of
+ * >> has changed: it now refers to both the tens and the ones digits. The meaning of
+ * both substitutions depends on the rule's base value. The base value determines the rule's divisor,
+ * which is the highest power of 10 that is less than or equal to the base value (the user
+ * can change this). To fill in the substitutions, the formatter divides the number being
+ * formatted by the divisor. The integral quotient is used to fill in the <<
+ * substitution, and the remainder is used to fill in the >> substitution. The meaning
+ * of the brackets changes similarly: text in brackets is omitted if the value being
+ * formatted is an even multiple of the rule's divisor. The rules are applied recursively, so
+ * if a substitution is filled in with text that includes another substitution, that
+ * substitution is also filled in.

+ *
+ * 
This rule covers values up to 999, at which point we add another rule:

+ *
+ * 
1000: << thousand[ >>];

+ *
+ * 
Again, the meanings of the brackets and substitution tokens shift because the rule's
+ * base value is a higher power of 10, changing the rule's divisor. This rule can actually be
+ * used all the way up to 999,999. This allows us to finish out the rules as follows:

+ *
+ * 
 1,000,000: << million[ >>];
+ * 1,000,000,000: << billion[ >>];
+ * 1,000,000,000,000: << trillion[ >>];
+ * 1,000,000,000,000,000: OUT OF RANGE!;

+ *
+ * 
Commas, periods, and spaces can be used in the base values to improve legibility and
+ * are ignored by the rule parser. The last rule in the list is customarily treated as an
+ * "overflow rule," applying to everything from its base value on up, and often (as
+ * in this example) being used to print out an error message or default representation.
+ * Notice also that the size of the major groupings in large numbers is controlled by the
+ * spacing of the rules: because in English we group numbers by thousand, the higher rules
+ * are separated from each other by a factor of 1,000.

+ *
+ * 
To see how these rules actually work in practice, consider the following example:
+ * Formatting 25,430 with this rule set would work like this:

+ *
+ * 
+ *   
+ *     
+ *     
+ *   
+ *   
+ *     
+ *     
+ *   
+ *   
+ *     
+ *     
+ *   
+ *   
+ *     
+ *     
+ *   
+ *   
+ *     
+ *     
+ *   
+ *   
+ *     
+ *     
+ *   
+ * 
<< thousand >>[the rule whose base value is 1,000 is applicable to 25,340]
twenty->> thousand >>[25,340 over 1,000 is 25. The rule for 20 applies.]
twenty-five thousand >>[25 mod 10 is 5. The rule for 5 is "five."
twenty-five thousand << hundred >>[25,340 mod 1,000 is 340. The rule for 100 applies.]
twenty-five thousand three hundred >>[340 over 100 is 3. The rule for 3 is "three."]
twenty-five thousand three hundred forty[340 mod 100 is 40. The rule for 40 applies. Since 40 divides
+ *     evenly by 10, the hyphen and substitution in the brackets are omitted.]

+ *
+ * 
The above syntax suffices only to format positive integers. To format negative numbers,
+ * we add a special rule:

+ *
+ * 
-x: minus >>;

+ *
+ * 
This is called a negative-number rule, and is identified by "-x"
+ * where the base value would be. This rule is used to format all negative numbers. the
+ * >> token here means "find the number's absolute value, format it with these
+ * rules, and put the result here."

+ *
+ * 
We also add a special rule called a fraction rule for numbers with fractional
+ * parts:

+ *
+ * 
x.x: << point >>;

+ *
+ * 
This rule is used for all positive non-integers (negative non-integers pass through the
+ * negative-number rule first and then through this rule). Here, the << token refers to
+ * the number's integral part, and the >> to the number's fractional part. The
+ * fractional part is formatted as a series of single-digit numbers (e.g., 123.456 would be
+ * formatted as "one hundred twenty-three point four five six").

+ *
+ * 
To see how this rule syntax is applied to various languages, examine the resource data.

+ *
+ * 
There is actually much more flexibility built into the rule language than the
+ * description above shows. A formatter may own multiple rule sets, which can be selected by
+ * the caller, and which can use each other to fill in their substitutions. Substitutions can
+ * also be filled in with digits, using a DecimalFormat object. There is syntax that can be
+ * used to alter a rule's divisor in various ways. And there is provision for much more
+ * flexible fraction handling. A complete description of the rule syntax follows:

+ *
+ * 

+ *
+ * 
The description of a RuleBasedNumberFormat's behavior consists of one or more rule
+ * sets. Each rule set consists of a name, a colon, and a list of rules. A rule
+ * set name must begin with a % sign. Rule sets with names that begin with a single % sign
+ * are public: the caller can specify that they be used to format and parse numbers.
+ * Rule sets with names that begin with %% are private: they exist only for the use
+ * of other rule sets. If a formatter only has one rule set, the name may be omitted.

+ *
+ * 
The user can also specify a special "rule set" named %%lenient-parse.
+ * The body of %%lenient-parse isn't a set of number-formatting rules, but a RuleBasedCollator
+ * description which is used to define equivalences for lenient parsing. For more information
+ * on the syntax, see RuleBasedCollator. For more information on lenient parsing,
+ * see setLenientParse().  Note: symbols that have syntactic meaning
+ * in collation rules, such as '&', have no particular meaning when appearing outside
+ * of the lenient-parse rule set.

+ *
+ * 
The body of a rule set consists of an ordered, semicolon-delimited list of rules.
+ * Internally, every rule has a base value, a divisor, rule text, and zero, one, or two substitutions.
+ * These parameters are controlled by the description syntax, which consists of a rule
+ * descriptor, a colon, and a rule body.

+ *
+ * 
A rule descriptor can take one of the following forms (text in italics is the
+ * name of a token):

+ *
+ * 
+ *   
+ *     
+ *     
+ *   
+ *   
+ *     
+ *     
+ *   
+ *   
+ *     
+ *     
+ *   
+ *   
+ *     
+ *     
+ *   
+ *   
+ *     
+ *     
+ *   
+ *   
+ *     
+ *     
+ *   
+ *   
+ *

+ *   
+ *     
+ *     
+ *   
+ * 
bv:bv specifies the rule's base value. bv is a decimal
+ *     number expressed using ASCII digits. bv may contain spaces, period, and commas,
+ *     which are ignored. The rule's divisor is the highest power of 10 less than or equal to
+ *     the base value.
bv/rad:bv specifies the rule's base value. The rule's divisor is the
+ *     highest power of rad less than or equal to the base value.
bv>:bv specifies the rule's base value. To calculate the divisor,
+ *     let the radix be 10, and the exponent be the highest exponent of the radix that yields a
+ *     result less than or equal to the base value. Every > character after the base value
+ *     decreases the exponent by 1. If the exponent is positive or 0, the divisor is the radix
+ *     raised to the power of the exponent; otherwise, the divisor is 1.
bv/rad>:bv specifies the rule's base value. To calculate the divisor,
+ *     let the radix be rad, and the exponent be the highest exponent of the radix that
+ *     yields a result less than or equal to the base value. Every > character after the radix
+ *     decreases the exponent by 1. If the exponent is positive or 0, the divisor is the radix
+ *     raised to the power of the exponent; otherwise, the divisor is 1.
-x:The rule is a negative-number rule.
x.x:The rule is an improper fraction rule. If the full stop in
+ *     the middle of the rule name is replaced with the decimal point
+ *     that is used in the language or DecimalFormatSymbols, then that rule will
+ *     have precedence when formatting and parsing this rule. For example, some
+ *     languages use the comma, and can thus be written as x,x instead. For example,
+ *     you can use "x.x: << point >>;x,x: << comma >>;" to
+ *     handle the decimal point that matches the language's natural spelling of
+ *     the punctuation of either the full stop or comma.
0.x:The rule is a proper fraction rule. If the full stop in
+ *     the middle of the rule name is replaced with the decimal point
+ *     that is used in the language or DecimalFormatSymbols, then that rule will
+ *     have precedence when formatting and parsing this rule. For example, some
+ *     languages use the comma, and can thus be written as 0,x instead. For example,
+ *     you can use "0.x: point >>;0,x: comma >>;" to
+ *     handle the decimal point that matches the language's natural spelling of
+ *     the punctuation of either the full stop or comma.
x.0:The rule is a default rule. If the full stop in
+ *     the middle of the rule name is replaced with the decimal point
+ *     that is used in the language or DecimalFormatSymbols, then that rule will
+ *     have precedence when formatting and parsing this rule. For example, some
+ *     languages use the comma, and can thus be written as x,0 instead. For example,
+ *     you can use "x.0: << point;x,0: << comma;" to
+ *     handle the decimal point that matches the language's natural spelling of
+ *     the punctuation of either the full stop or comma.
Inf:The rule for infinity.
NaN:The rule for an IEEE 754 NaN (not a number).
nothingIf the rule's rule descriptor is left out, the base value is one plus the
+ *     preceding rule's base value (or zero if this is the first rule in the list) in a normal
+ *     rule set.  In a fraction rule set, the base value is the same as the preceding rule's
+ *     base value.

+ *
+ * 
A rule set may be either a regular rule set or a fraction rule set, depending
+ * on whether it is used to format a number's integral part (or the whole number) or a
+ * number's fractional part. Using a rule set to format a rule's fractional part makes it a
+ * fraction rule set.

+ *
+ * 
Which rule is used to format a number is defined according to one of the following
+ * algorithms: If the rule set is a regular rule set, do the following:
+ *
+ * 
    
+ *   
  • If the rule set includes a default rule (and the number was passed in as a double),
+ *     use the default rule.  (If the number being formatted was passed in as a long,
+ *     the default rule is ignored.)
    • 
+ *   
  • If the number is negative, use the negative-number rule.
    • 
+ *   
  • If the number has a fractional part and is greater than 1, use the improper fraction
+ *     rule.
    • 
+ *   
  • If the number has a fractional part and is between 0 and 1, use the proper fraction
+ *     rule.
    • 
+ *   
  • Binary-search the rule list for the rule with the highest base value less than or equal
+ *     to the number. If that rule has two substitutions, its base value is not an even multiple
+ *     of its divisor, and the number is an even multiple of the rule's divisor, use the
+ *     rule that precedes it in the rule list. Otherwise, use the rule itself.
    • 
+ * 

+ *
+ * 
If the rule set is a fraction rule set, do the following:
+ *
+ * 
    
+ *   
  • Ignore negative-number and fraction rules.
    • 
+ *   
  • For each rule in the list, multiply the number being formatted (which will always be
+ *     between 0 and 1) by the rule's base value. Keep track of the distance between the result
+ *     the nearest integer.
    • 
+ *   
  • Use the rule that produced the result closest to zero in the above calculation. In the
+ *     event of a tie or a direct hit, use the first matching rule encountered. (The idea here is
+ *     to try each rule's base value as a possible denominator of a fraction. Whichever
+ *     denominator produces the fraction closest in value to the number being formatted wins.) If
+ *     the rule following the matching rule has the same base value, use it if the numerator of
+ *     the fraction is anything other than 1; if the numerator is 1, use the original matching
+ *     rule. (This is to allow singular and plural forms of the rule text without a lot of extra
+ *     hassle.)
    • 
+ * 

+ *
+ * 
A rule's body consists of a string of characters terminated by a semicolon. The rule
+ * may include zero, one, or two substitution tokens, and a range of text in
+ * brackets. The brackets denote optional text (and may also include one or both
+ * substitutions). The exact meanings of the substitution tokens, and under what conditions
+ * optional text is omitted, depend on the syntax of the substitution token and the context.
+ * The rest of the text in a rule body is literal text that is output when the rule matches
+ * the number being formatted.

+ *
+ * 
A substitution token begins and ends with a token character. The token
+ * character and the context together specify a mathematical operation to be performed on the
+ * number being formatted. An optional substitution descriptor specifies how the
+ * value resulting from that operation is used to fill in the substitution. The position of
+ * the substitution token in the rule body specifies the location of the resultant text in
+ * the original rule text.

+ *
+ * 
The meanings of the substitution token characters are as follows:

+ *
+ * 
+ *   
+ *     
+ *     
+ *     
+ *   
+ *

$(cardinal,plural syntax)$in all rule setsThis provides the ability to choose a word based on the number divided by the radix to the power of the

+ *     This uses the cardinal plural rules from PluralFormat. All strings used in the plural format are treated
+ *     as the same base value for parsing.
$(ordinal,plural syntax)$in all rule setsThis provides the ability to choose a word based on the number divided by the radix to the power of the

The substitution descriptor (i.e., the text between the token characters) may take one

+ *
+ * 
+ *   
+ *     
+ *     
+ *   
+ *   
+ *     
+ *     
+ *   
+ *   
+ *     
+ *     
+ *   
+ * 
a rule set namePerform the mathematical operation on the number, and format the result using the
+ *     named rule set.
a DecimalFormat patternPerform the mathematical operation on the number, and format the result using a
+ *     DecimalFormat with the specified pattern.  The pattern must begin with 0 or #.
nothingPerform the mathematical operation on the number, and format the result using the rule
+ *     set containing the current rule, except:
+ *     
    
+ *       
  • You can't have an empty substitution descriptor with a == substitution.
    • 
+ *       
  • If you omit the substitution descriptor in a >> substitution in a fraction rule,
+ *         format the result one digit at a time using the rule set containing the current rule.
    • 
+ *       
  • If you omit the substitution descriptor in a << substitution in a rule in a
+ *         fraction rule set, format the result using the default rule set for this formatter.
    • 
+ *     

+ *     

+ *
+ * 
Whitespace is ignored between a rule set name and a rule set body, between a rule
+ * descriptor and a rule body, or between rules. If a rule body begins with an apostrophe,
+ * the apostrophe is ignored, but all text after it becomes significant (this is how you can
+ * have a rule's rule text begin with whitespace). There is no escape function: the semicolon
+ * is not allowed in rule set names or in rule text, and the colon is not allowed in rule set
+ * names. The characters beginning a substitution token are always treated as the beginning
+ * of a substitution token.

+ *
+ * 
See the resource data and the demo program for annotated examples of real rule sets
+ * using these features.

+ *
+ * 
User subclasses are not supported. While clients may write
+ * subclasses, such code will not necessarily work and will not be
+ * guaranteed to work stably from release to release.
+ *
+ * 
Localizations

+ * 
Constructors are available that allow the specification of localizations for the
+ * public rule sets (and also allow more control over what public rule sets are available).
+ * Localization data is represented as a textual description.  The description represents
+ * an array of arrays of string.  The first element is an array of the public rule set names,
+ * each of these must be one of the public rule set names that appear in the rules.  Only
+ * names in this array will be treated as public rule set names by the API.  Each subsequent
+ * element is an array of localizations of these names.  The first element of one of these
+ * subarrays is the locale name, and the remaining elements are localizations of the
+ * public rule set names, in the same order as they were listed in the first array.

+ * 
In the syntax, angle brackets '<', '>' are used to delimit the arrays, and comma ',' is used
+ * to separate elements of an array.  Whitespace is ignored, unless quoted.

+ * 
For example:
+ * < < %foo, %bar, %baz >,
+ *   < en, Foo, Bar, Baz >,
+ *   < fr, 'le Foo', 'le Bar', 'le Baz' >
+ *   < zh, \\u7532, \\u4e59, \\u4e19 > >

+ *
+ * The ICU API for processing regular expressions consists of two classes,
+ *  `RegexPattern` and `RegexMatcher`.
+ *  `RegexPattern` objects represent a pre-processed, or compiled
+ *  regular expression.  They are created from a regular expression pattern string,
+ *  and can be used to create `RegexMatcher` objects for the pattern.
+ *
+ * Class `RegexMatcher` bundles together a regular expression
+ *  pattern and a target string to which the search pattern will be applied.
+ *  `RegexMatcher` includes API for doing plain find or search
+ *  operations, for search and replace operations, and for obtaining detailed
+ *  information about bounds of a match.
+ *
+ * Note that by constructing `RegexMatcher` objects directly from regular
+ * expression pattern strings application code can be simplified and the explicit
+ * need for `RegexPattern` objects can usually be eliminated.

+/**
+ * Region is the class representing a Unicode Region Code, also known as a 
+ * Unicode Region Subtag, which is defined based upon the BCP 47 standard. We often think of
+ * "regions" as "countries" when defining the characteristics of a locale.  Region codes There are different
+ * types of region codes that are important to distinguish.
+ * 

+ *  Macroregion - A code for a "macro geographical (continental) region, geographical sub-region, or 
+ *  selected economic and other grouping" as defined in 
+ *  UN M.49 (http://unstats.un.org/unsd/methods/m49/m49regin.htm). 
+ *  These are typically 3-digit codes, but contain some 2-letter codes, such as the LDML code QO 
+ *  added for Outlying Oceania.  Not all UNM.49 codes are defined in LDML, but most of them are.
+ *  Macroregions are represented in ICU by one of three region types: WORLD ( region code 001 ),
+ *  CONTINENTS ( regions contained directly by WORLD ), and SUBCONTINENTS ( things contained directly
+ *  by a continent ).
+ *  

+ *  TERRITORY - A Region that is not a Macroregion. These are typically codes for countries, but also
+ *  include areas that are not separate countries, such as the code "AQ" for Antarctica or the code 
+ *  "HK" for Hong Kong (SAR China). Overseas dependencies of countries may or may not have separate 
+ *  codes. The codes are typically 2-letter codes aligned with the ISO 3166 standard, but BCP47 allows
+ *  for the use of 3-digit codes in the future.
+ *  

+ *  UNKNOWN - The code ZZ is defined by Unicode LDML for use to indicate that the Region is unknown,
+ *  or that the value supplied as a region was invalid.
+ *  

+ *  DEPRECATED - Region codes that have been defined in the past but are no longer in modern usage,
+ *  usually due to a country splitting into multiple territories or changing its name.
+ *  

+ *  GROUPING - A widely understood grouping of territories that has a well defined membership such
+ *  that a region code has been assigned for it.  Some of these are UNM.49 codes that do't fall into 
+ *  the world/continent/sub-continent hierarchy, while others are just well known groupings that have
+ *  their own region code. Region "EU" (European Union) is one such region code that is a grouping.
+ *  Groupings will never be returned by the getContainingRegion() API, since a different type of region
+ *  ( WORLD, CONTINENT, or SUBCONTINENT ) will always be the containing region instead.
+ *
+ * The Region class is not intended for public subclassing.

+ * This API is very basic and is intended to be a building block for more

+ * e.g "in 5 days and 4 hours" nor does it support parsing.
+ * 

+ * This class is mostly thread safe and immutable with the following caveats:
+ * 1. The assignment operator violates Immutability. It must not be used
+ *    concurrently with other operations.
+ * 2. Caller must not hold onto adopted pointers.
+ *

+
+class UnicodeString;
+
+/**
+ * Replaceable is an abstract base class representing a
+ * string of characters that supports the replacement of a range of
+ * itself with a new string of characters.  It is used by APIs that
+ * change a piece of text while retaining metadata.  Metadata is data
+ * other than the Unicode characters returned by char32At().  One
+ * example of metadata is style attributes; another is an edit
+ * history, marking each character with an author and revision number.
+ *
+ * 
An implicit aspect of the Replaceable API is that
+ * during a replace operation, new characters take on the metadata of
+ * the old characters.  For example, if the string "the bold
+ * font" has range (4, 8) replaced with "strong", then it becomes "the
+ * strong font".
+ *
+ * 
Replaceable specifies ranges using a start
+ * offset and a limit offset.  The range of characters thus specified
+ * includes the characters at offset start..limit-1.  That is, the
+ * start offset is inclusive, and the limit offset is exclusive.
+ *
+ * 
Replaceable also includes API to access characters
+ * in the string: length(), charAt(),
+ * char32At(), and extractBetween().
+ *
+ * 
For a subclass to support metadata, typical behavior of
+ * replace() is the following:
+ * 
    
+ *   
  • Set the metadata of the new text to the metadata of the first
+ *   character replaced
    • 
+ *   
  • If no characters are replaced, use the metadata of the
+ *   previous character
    • 
+ *   
  • If there is no previous character (i.e. start == 0), use the
+ *   following character
    • 
+ *   
  • If there is no following character (i.e. the replaceable was
+ *   empty), use default metadata.
    
+ *   
  • If the code point U+FFFF is seen, it should be interpreted as
+ *   a special marker having no metadata
  • 
+ *   
    • 
+ * 

+ * If this is not the behavior, the subclass should document any differences.

+* Modification History:
+*
+*   Date        Name        Description
+*   2/5/97      aliu        Added scanForLocaleInFile.  Added
+*                           constructor which attempts to read resource bundle
+*                           from a specific file, without searching other files.
+*   2/11/97     aliu        Added UErrorCode return values to constructors.  Fixed
+*                           infinite loops in scanForFile and scanForLocale.
+*                           Modified getRawResourceData to not delete storage
+*                           in localeData and resourceData which it doesn't own.
+*                           Added Mac compatibility #ifdefs for tellp() and
+*                           ios::nocreate.
+*   2/18/97     helena      Updated with 100% documentation coverage.
+*   3/13/97     aliu        Rewrote to load in entire resource bundle and store
+*                           it as a Hashtable of ResourceBundleData objects.
+*                           Added state table to govern parsing of files.
+*                           Modified to load locale index out of new file
+*                           distinct from default.txt.
+*   3/25/97     aliu        Modified to support 2-d arrays, needed for timezone
+*                           data. Added support for custom file suffixes.  Again,
+*                           needed to support timezone data.
+*   4/7/97      aliu        Cleaned up.
+* 03/02/99      stephen     Removed dependency on FILE*.
+* 03/29/99      helena      Merged Bertrand and Stephen's changes.
+* 06/11/99      stephen     Removed parsing of .txt files.
+*                           Reworked to use new binary format.
+*                           Cleaned up.
+* 06/14/99      stephen     Removed methods taking a filename suffix.

+ * 

+ * Resource bundles in ICU4C are currently defined using text files which conform to the following
+ * BNF definition.
+ * More on resource bundle concepts and syntax can be found in the
+ * Users Guide.

+     *                for the French locale, for example, you would create a
+     *                ResourceBundle passing Locale::FRENCH for the "locale" parameter,

+     *                returned by Locale::getDefault()) will be used.
+     * @param err     The Error Code.
+     * The UErrorCode& err parameter is used to return status information to the user. To
+     * check whether the construction succeeded or not, you should check the value of
+     * U_SUCCESS(err). If you wish more detailed information, you can check for
+     * informational error results which still indicate success. U_USING_FALLBACK_WARNING
+     * indicates that a fall back locale was used. For example, 'de_CH' was requested,
+     * but nothing was found there, so 'de' was used. U_USING_DEFAULT_WARNING indicates that

+ * matching based on the comparison rules defined in a 
+ * RuleBasedCollator object. 
+ * 
 
+ * Other options for searching includes using a BreakIterator to restrict 
+ * the points at which matches are detected.
+ * 

+ * SearchIterator provides an API that is similar to that of
+ * other text iteration classes such as BreakIterator. Using 
+ * this class, it is easy to scan through text looking for all occurrences of 
+ * a given pattern. The following example uses a StringSearch 
+ * object to find all instances of "fox" in the target string. Any other 
+ * subclass of SearchIterator can be used in an identical 
+ * manner.
+ * 

+ * UnicodeString target("The quick brown fox jumped over the lazy fox");
+ * UnicodeString pattern("fox");
+ *
+ * SearchIterator *iter  = new StringSearch(pattern, target);
+ * UErrorCode      error = U_ZERO_ERROR;
+ * for (int pos = iter->first(error); pos != USEARCH_DONE; 
+ *                               pos = iter->next(error)) {
+ *     printf("Found match at %d pos, length is %d\n", pos, iter.getMatchedLength());
+ * }

+/**
+  * 
SelectFormat supports the creation of  internationalized
+  * messages by selecting phrases based on keywords. The pattern  specifies
+  * how to map keywords to phrases and provides a default phrase. The
+  * object provided to the format method is a string that's matched
+  * against the keywords. If there is a match, the corresponding phrase
+  * is selected; otherwise, the default phrase is used.

+  *
+  * 
Using SelectFormat for Gender Agreement

+  *
+  * 
Note: Typically, select formatting is done via MessageFormat
+  * with a select argument type,
+  * rather than using a stand-alone SelectFormat.

+  *
+  * 
The main use case for the select format is gender based  inflection.
+  * When names or nouns are inserted into sentences, their gender can  affect pronouns,
+  * verb forms, articles, and adjectives. Special care needs to be
+  * taken for the case where the gender cannot be determined.
+  * The impact varies between languages:

+  * \htmlonly
+  * 
    
+  * 
  • English has three genders, and unknown gender is handled as a  special
+  * case. Names use the gender of the named person (if known), nouns  referring
+  * to people use natural gender, and inanimate objects are usually  neutral.
+  * The gender only affects pronouns: "he", "she", "it", "they".
+  *
+  * 
  • German differs from English in that the gender of nouns is  rather
+  * arbitrary, even for nouns referring to people ("Mädchen", girl, is  neutral).
+  * The gender affects pronouns ("er", "sie", "es"), articles ("der",  "die",
+  * "das"), and adjective forms ("guter Mann", "gute Frau", "gutes  Mädchen").
+  *
+  * 
  • French has only two genders; as in German the gender of nouns
+  * is rather arbitrary - for sun and moon, the genders
+  * are the opposite of those in German. The gender affects
+  * pronouns ("il", "elle"), articles ("le", "la"),
+  * adjective forms ("bon", "bonne"), and sometimes
+  * verb forms ("allé", "allée").
+  *
+  * 
  • Polish distinguishes five genders (or noun classes),
+  * human masculine, animate non-human masculine, inanimate masculine,
+  * feminine, and neuter.
+  * 

+  * \endhtmlonly
+  * 
Some other languages have noun classes that are not related to  gender,
+  * but similar in grammatical use.
+  * Some African languages have around 20 noun classes.

+  *
+  * 
Note:For the gender of a person in a given sentence,
+  * we usually need to distinguish only between female, male and other/unknown.

+  *
+  * 
To enable localizers to create sentence patterns that take their
+  * language's gender dependencies into consideration, software has to  provide
+  * information about the gender associated with a noun or name to
+  * MessageFormat.
+  * Two main cases can be distinguished:

+  *
+  * 
    
+  * 
  • For people, natural gender information should be maintained  for each person.
+  * Keywords like "male", "female", "mixed" (for groups of people)
+  * and "unknown" could be used.
+  *
+  * 
  • For nouns, grammatical gender information should be maintained  for
+  * each noun and per language, e.g., in resource bundles.
+  * The keywords "masculine", "feminine", and "neuter" are commonly  used,
+  * but some languages may require other keywords.
+  * 

+  *
+  * 
The resulting keyword is provided to MessageFormat  as a
+  * parameter separate from the name or noun it's associated with. For  example,
+  * to generate a message such as "Jean went to Paris", three separate  arguments
+  * would be provided: The name of the person as argument 0, the  gender of
+  * the person as argument 1, and the name of the city as argument 2.
+  * The sentence pattern for English, where the gender of the person has
+  * no impact on this simple sentence, would not refer to argument 1  at all:

+  *
+  * 
{0} went to {2}.

+  *
+  * 
Note: The entire sentence should be included (and partially repeated)
+  * inside each phrase. Otherwise translators would have to be trained on how to
+  * move bits of the sentence in and out of the select argument of a message.
+  * (The examples below do not follow this recommendation!)

+  *
+  * 
The sentence pattern for French, where the gender of the person affects
+  * the form of the participle, uses a select format based on argument 1:

+  *
+  * \htmlonly
{0} est {1, select, female {allée} other {allé}} à {2}.
\endhtmlonly
+  *
+  * 
Patterns can be nested, so that it's possible to handle  interactions of
+  * number and gender where necessary. For example, if the above  sentence should
+  * allow for the names of several people to be inserted, the  following sentence
+  * pattern can be used (with argument 0 the list of people's names,
+  * argument 1 the number of people, argument 2 their combined gender, and
+  * argument 3 the city name):

+  *
+  * \htmlonly
+  * 
{0} {1, plural,
+  *                 one {est {2, select, female {allée} other  {allé}}}
+  *                 other {sont {2, select, female {allées} other {allés}}}
+  *          }à {3}.

+  * \endhtmlonly
+  *
+  * 
Patterns and Their Interpretation

+  *
+  * 
The SelectFormat pattern string defines the phrase output
+  * for each user-defined keyword.
+  * The pattern is a sequence of (keyword, message) pairs.
+  * A keyword is a "pattern identifier": [^[[:Pattern_Syntax:][:Pattern_White_Space:]]]+

+  *
+  * 
Each message is a MessageFormat pattern string enclosed in {curly braces}.

+  *
+  * 
You always have to define a phrase for the default keyword
+  * other; this phrase is returned when the keyword
+  * provided to
+  * the format method matches no other keyword.
+  * If a pattern does not provide a phrase for other, the  method
+  * it's provided to returns the error  U_DEFAULT_KEYWORD_MISSING.
+  * 

+  * Pattern_White_Space between keywords and messages is ignored.
+  * Pattern_White_Space within a message is preserved and output.

+  *
+  * 
Example:
+  * \htmlonly
+  *
+  * UErrorCode status = U_ZERO_ERROR;
+  * MessageFormat *msgFmt = new MessageFormat(UnicodeString("{0} est  {1, select, female {allée} other {allé}} à Paris."), Locale("fr"),  status);
+  * if (U_FAILURE(status)) {
+  *       return;
+  * }
+  * FieldPosition ignore(FieldPosition::DONT_CARE);
+  * UnicodeString result;
+  *
+  * char* str1= "Kirti,female";
+  * Formattable args1[] = {"Kirti","female"};
+  * msgFmt->format(args1, 2, result, ignore, status);
+  * cout << "Input is " << str1 << " and result is: " << result << endl;
+  * delete msgFmt;
+  *
+  * \endhtmlonly
+  * 

+  * 

+  *
+  * Produces the output:

+  * \htmlonly
+  * Kirti est allée à Paris.
+  * \endhtmlonly

+/**
+ *
+ * SimpleDateFormat is a concrete class for formatting and parsing dates in a
+ * language-independent manner. It allows for formatting (millis -> text),
+ * parsing (text -> millis), and normalization. Formats/Parses a date or time,
+ * which is the standard milliseconds since 24:00 GMT, Jan 1, 1970.
+ * 

+ * Clients are encouraged to create a date-time formatter using DateFormat::getInstance(),
+ * getDateInstance(), getDateInstance(), or getDateTimeInstance() rather than
+ * explicitly constructing an instance of SimpleDateFormat.  This way, the client
+ * is guaranteed to get an appropriate formatting pattern for whatever locale the
+ * program is running in.  However, if the client needs something more unusual than
+ * the default patterns in the locales, he can construct a SimpleDateFormat directly
+ * and give it an appropriate pattern (or use one of the factory methods on DateFormat
+ * and modify the pattern after the fact with toPattern() and applyPattern().
+ *
+ * 
Date and Time Patterns:

+ *
+ * 
Date and time formats are specified by date and time pattern strings.
+ * Within date and time pattern strings, all unquoted ASCII letters [A-Za-z] are reserved
+ * as pattern letters representing calendar fields. SimpleDateFormat supports
+ * the date and time formatting algorithm and pattern letters defined by
+ * UTS#35
+ * Unicode Locale Data Markup Language (LDML) and further documented for ICU in the
+ * ICU
+ * User Guide. The following pattern letters are currently available (note that the actual
+ * values depend on CLDR and may change from the examples shown here):

Y1..n1997Year (in "Week of Year" based calendars). Normally the length specifies the padding,
+ *         but for two letters it also specifies the maximum length. This year designation is used in ISO
+ *         year-week calendar as defined by ISO 8601, but can be used in non-Gregorian based calendar systems
+ *         where week date processing is desired. May not always be the same value as calendar year.
u1..n4601Extended year. This is a single number designating the year of this calendar system, encompassing
+ *         all supra-year fields. For example, for the Julian calendar system, year numbers are positive, with an
+ *         era of BCE or CE. An extended year value for the Julian calendar system assigns positive values to CE
+ *         years and negative values to BCE years, with 1 BCE being year 0.
U1..3甲子Cyclic year name. Calendars such as the Chinese lunar calendar (and related calendars)
+ *         and the Hindu calendars use 60-year cycles of year names. Use one through three letters for the abbreviated
+ *         name, four for the full (wide) name, or five for the narrow name (currently the data only provides abbreviated names,
+ *         which will be used for all requested name widths). If the calendar does not provide cyclic year name data,
+ *         or if the year value to be formatted is out of the range of years for which cyclic name data is provided,
+ *         then numeric formatting is used (behaves like 'y').

V1uslaxThe short time zone ID.

+ *         Note: This specifier was originally used for a variant of the short specific non-location format,
+ *         but it was deprecated in the later version of the LDML specification. In CLDR 23/ICU 51, the definition of
+ *         the specifier was changed to designate a short time zone ID.
2America/Los_AngelesThe long time zone ID.
3Los AngelesThe exemplar city (location) for the time zone.
+ *         Where that is unavailable, the localized exemplar city name for the special zone Etc/Unknown is used
+ *         as the fallback (for example, "Unknown City"). 
4Los Angeles TimeThe generic location format.
+ *         Where that is unavailable, falls back to the long localized GMT format ("OOOO";
+ *         Note: Fallback is only necessary with a GMT-style Time Zone ID, like Etc/GMT-830.)

+ *         This is especially useful when presenting possible timezone choices for user selection,
+ *         since the naming is more uniform than the "v" format.

+ * 

+ * Code Sample:
+ * 
+ * \code
+ *     UErrorCode success = U_ZERO_ERROR;
+ *     SimpleTimeZone* pdt = new SimpleTimeZone(-8 * 60 * 60 * 1000, "PST");
+ *     pdt->setStartRule( Calendar::APRIL, 1, Calendar::SUNDAY, 2*60*60*1000);
+ *     pdt->setEndRule( Calendar::OCTOBER, -1, Calendar::SUNDAY, 2*60*60*1000);
+ *
+ *     // Format the current time.
+ *     SimpleDateFormat* formatter
+ *         = new SimpleDateFormat ("yyyy.MM.dd G 'at' hh:mm:ss a zzz", success );
+ *     GregorianCalendar cal(success);
+ *     UDate currentTime_1 = cal.getTime(success);
+ *     FieldPosition fp(FieldPosition::DONT_CARE);
+ *     UnicodeString dateString;
+ *     formatter->format( currentTime_1, dateString, fp );
+ *     cout << "result: " << dateString << endl;
+ *
+ *     // Parse the previous string back into a Date.
+ *     ParsePosition pp(0);
+ *     UDate currentTime_2 = formatter->parse(dateString, pp );
+ * \endcode
+ * 

+ * In the above example, the time value "currentTime_2" obtained from parsing
+ * will be equal to currentTime_1. However, they may not be equal if the am/pm
+ * marker 'a' is left out from the format pattern while the "hour in am/pm"
+ * pattern symbol is used. This information loss can happen when formatting the
+ * time in PM.
+ *
+ * 

+ * When parsing a date string using the abbreviated year pattern ("y" or "yy"),
+ * SimpleDateFormat must interpret the abbreviated year
+ * relative to some century.  It does this by adjusting dates to be
+ * within 80 years before and 20 years after the time the SimpleDateFormat
+ * instance is created. For example, using a pattern of "MM/dd/yy" and a
+ * SimpleDateFormat instance created on Jan 1, 1997,  the string
+ * "01/11/12" would be interpreted as Jan 11, 2012 while the string "05/04/64"
+ * would be interpreted as May 4, 1964.
+ * During parsing, only strings consisting of exactly two digits, as defined by
+ * Unicode::isDigit(), will be parsed into the default century.
+ * Any other numeric string, such as a one digit string, a three or more digit
+ * string, or a two digit string that isn't all digits (for example, "-1"), is
+ * interpreted literally.  So "01/02/3" or "01/02/003" are parsed (for the
+ * Gregorian calendar), using the same pattern, as Jan 2, 3 AD.  Likewise (but
+ * only in lenient parse mode, the default) "01/02/-3" is parsed as Jan 2, 4 BC.
+ *
+ * 

+ * If the year pattern has more than two 'y' characters, the year is
+ * interpreted literally, regardless of the number of digits.  So using the
+ * pattern "MM/dd/yyyy", "01/11/12" parses to Jan 11, 12 A.D.
+ *
+ * 

+ * When numeric fields abut one another directly, with no intervening delimiter
+ * characters, they constitute a run of abutting numeric fields.  Such runs are
+ * parsed specially.  For example, the format "HHmmss" parses the input text
+ * "123456" to 12:34:56, parses the input text "12345" to 1:23:45, and fails to
+ * parse "1234".  In other words, the leftmost field of the run is flexible,
+ * while the others keep a fixed width.  If the parse fails anywhere in the run,
+ * then the leftmost field is shortened by one character, and the entire run is
+ * parsed again. This is repeated until either the parse succeeds or the
+ * leftmost field is one character in length.  If the parse still fails at that
+ * point, the parse of the run fails.
+ *
+ * 

+ * For time zones that have no names, SimpleDateFormat uses strings GMT+hours:minutes or
+ * GMT-hours:minutes.
+ * 

+ * The calendar defines what is the first day of the week, the first week of the
+ * year, whether hours are zero based or not (0 vs 12 or 24), and the timezone.
+ * There is one common number format to handle all the numbers; the digit count
+ * is handled programmatically according to the pattern.
+ *
+ * 
User subclasses are not supported. While clients may write
+ * subclasses, such code will not necessarily work and will not be
+ * guaranteed to work stably from release to release.

+/**
+ *
+ * Collation keys are generated by the Collator class.  Use the CollationKey objects
+ * instead of Collator to compare strings multiple times.  A CollationKey
+ * preprocesses the comparison information from the Collator object to
+ * make the comparison faster.  If you are not going to comparing strings
+ * multiple times, then using the Collator object is generally faster,
+ * since it only processes as much of the string as needed to make a
+ * comparison.
+ * 
 For example (with strength == tertiary)
+ * 
When comparing "Abernathy" to "Baggins-Smythworthy", Collator
+ * only needs to process a couple of characters, while a comparison
+ * with CollationKeys will process all of the characters.  On the other hand,
+ * if you are doing a sort of a number of fields, it is much faster to use
+ * CollationKeys, since you will be comparing strings multiple times.
+ * 
Typical use of CollationKeys are in databases, where you store a CollationKey
+ * in a hidden field, and use it for sorting or indexing.
+ *
+ * 
Example of use:
+ * 
+ * \code
+ *     UErrorCode success = U_ZERO_ERROR;
+ *     Collator* myCollator = Collator::createInstance(success);
+ *     CollationKey* keys = new CollationKey [3];
+ *     myCollator->getCollationKey("Tom", keys[0], success );
+ *     myCollator->getCollationKey("Dick", keys[1], success );
+ *     myCollator->getCollationKey("Harry", keys[2], success );
+ *
+ *     // Inside body of sort routine, compare keys this way:
+ *     CollationKey tmp;
+ *     if(keys[0].compareTo( keys[1] ) > 0 ) {
+ *         tmp = keys[0]; keys[0] = keys[1]; keys[1] = tmp;
+ *     }
+ *     //...
+ * \endcode
+ * 

+ * 
Because Collator::compare()'s algorithm is complex, it is faster to sort
+ * long lists of words by retrieving collation keys with Collator::getCollationKey().
+ * You can then cache the collation keys and compare them using CollationKey::compareTo().
+ * 

+ * Note: Collators with different Locale,
+ * CollationStrength and DecompositionMode settings will return different
+ * CollationKeys for the same set of strings. Locales have specific
+ * collation rules, and the way in which secondary and tertiary differences
+ * are taken into account, for example, will result in different CollationKeys
+ * for same strings.
+ *

+ * Base class for 'pure' C++ implementations of uenum api.  Adds a
+ * method that returns the next UnicodeString since in C++ this can
+ * be a common storage format for strings.
+ *
+ * 
The model is that the enumeration is over strings maintained by
+ * a 'service.'  At any point, the service might change, invalidating
+ * the enumerator (though this is expected to be rare).  The iterator
+ * returns an error if this has occurred.  Lack of the error is no
+ * guarantee that the service didn't change immediately after the
+ * call, so the returned string still might not be 'valid' on
+ * subsequent use.

+ *
+ * 
Strings may take the form of const char*, const char16_t*, or const
+ * UnicodeString*.  The type you get is determine by the variant of
+ * 'next' that you call.  In general the StringEnumeration is
+ * optimized for one of these types, but all StringEnumerations can
+ * return all types.  Returned strings are each terminated with a NUL.
+ * Depending on the service data, they might also include embedded NUL
+ * characters, so API is provided to optionally return the true
+ * length, counting the embedded NULs but not counting the terminating
+ * NUL.

+ *
+ * 
The pointers returned by next, unext, and snext become invalid
+ * upon any subsequent call to the enumeration's destructor, next,
+ * unext, snext, or reset.

+            if(offset<0 && (offsetStringSearch is a SearchIterator that provides
+ * language-sensitive text searching based on the comparison rules defined
+ * in a {@link RuleBasedCollator} object.
+ * StringSearch ensures that language eccentricity can be
+ * handled, e.g. for the German collator, characters ß and SS will be matched
+ * if case is chosen to be ignored.
+ * See the 
+ * "ICU Collation Design Document" for more information.
+ * 

+ * There are 2 match options for selection:

+ * Let S' be the sub-string of a text string S between the offsets start and
+ * end [start, end].
+ * 

+ * A pattern string P matches a text string S at the offsets [start, end]
+ * if
+ * 
 
+ * option 1. Some canonical equivalent of P matches some canonical equivalent
+ *           of S'
+ * option 2. P matches S' and if P starts or ends with a combining mark,
+ *           there exists no non-ignorable combining mark before or after S?
+ *           in S respectively.
+ * 

+ * Option 2. will be the default.
+ * 

+ * This search has APIs similar to that of other text iteration mechanisms 
+ * such as the break iterators in BreakIterator. Using these 
+ * APIs, it is easy to scan through text looking for all occurrences of 
+ * a given pattern. This search iterator allows changing of direction by 
+ * calling a reset followed by a next or previous.
+ * Though a direction change can occur without calling reset first,
+ * this operation comes with some speed penalty.
+ * Match results in the forward direction will match the result matches in
+ * the backwards direction in the reverse order
+ * 

+ * SearchIterator provides APIs to specify the starting position
+ * within the text string to be searched, e.g. setOffset,
+ * preceding and following. Since the
+ * starting position will be set as it is specified, please take note that
+ * there are some danger points which the search may render incorrect
+ * results:
+ * 
    
+ * 
  •  The midst of a substring that requires normalization.
+ * 
  •  If the following match is to be found, the position should not be the
+ *      second character which requires to be swapped with the preceding
+ *      character. Vice versa, if the preceding match is to be found,
+ *      position to search from should not be the first character which
+ *      requires to be swapped with the next character. E.g certain Thai and
+ *      Lao characters require swapping.
+ * 
  •  If a following pattern match is to be found, any position within a
+ *      contracting sequence except the first will fail. Vice versa if a
+ *      preceding pattern match is to be found, a invalid starting point
+ *      would be any character within a contracting sequence except the last.
+ * 

+ * 

+ * A BreakIterator can be used if only matches at logical breaks are desired.
+ * Using a BreakIterator will only give you results that exactly matches the
+ * boundaries given by the breakiterator. For instance the pattern "e" will
+ * not be found in the string "\u00e9" if a character break iterator is used.
+ * 

+ * Options are provided to handle overlapping matches.
+ * E.g. In English, overlapping matches produces the result 0 and 2
+ * for the pattern "abab" in the text "ababab", where else mutually
+ * exclusive matches only produce the result of 0.
+ * 

+ * Though collator attributes will be taken into consideration while
+ * performing matches, there are no APIs here for setting and getting the
+ * attributes. These attributes can be set by getting the collator
+ * from getCollator and using the APIs in coll.h.
+ * Lastly to update StringSearch to the new collator attributes,
+ * reset has to be called.
+ * 
 
+ * Restriction: 

+ * Currently there are no composite characters that consists of a
+ * character with combining class > 0 before a character with combining
+ * class == 0. However, if such a character exists in the future,
+ * StringSearch does not guarantee the results for option 1.
+ * 

+ * Consult the SearchIterator documentation for information on
+ * and examples of how to use instances of this class to implement text
+ * searching.

+ * An interface that defines both lookup protocol and parsing of

+ *
+ * 
A symbol table maintains two kinds of mappings.  The first is
+ * between symbolic names and their values.  For example, if the
+ * variable with the name "start" is set to the value "alpha"
+ * (perhaps, though not necessarily, through an expression such as
+ * "$start=alpha"), then the call lookup("start") will return the
+ * char[] array ['a', 'l', 'p', 'h', 'a'].
+ *
+ * 
The second kind of mapping is between character values and
+ * UnicodeMatcher objects.  This is used by RuleBasedTransliterator,
+ * which uses characters in the private use area to represent objects
+ * such as UnicodeSets.  If U+E015 is mapped to the UnicodeSet [a-z],
+ * then lookupMatcher(0xE015) will return the UnicodeSet [a-z].
+ *
+ * 
Finally, a symbol table defines parsing behavior for symbolic
+ * names.  All symbolic names start with the SYMBOL_REF character.
+ * When a parser encounters this character, it calls parseReference()
+ * with the position immediately following the SYMBOL_REF.  The symbol
+ * table parses the name, if there is one, and returns it.

+/**
+ *
+ * TimeZone represents a time zone offset, and also figures out daylight
+ * savings.
+ *
+ * 

+ * Typically, you get a TimeZone using createDefault
+ * which creates a TimeZone based on the time zone where the program
+ * is running. For example, for a program running in Japan, createDefault
+ * creates a TimeZone object based on Japanese Standard Time.
+ *
+ * 

+ * You can also get a TimeZone using createTimeZone along
+ * with a time zone ID. For instance, the time zone ID for the US Pacific
+ * Time zone is "America/Los_Angeles". So, you can get a Pacific Time TimeZone object
+ * with:
+ * \htmlonly
\endhtmlonly
+ * 
+ * TimeZone *tz = TimeZone::createTimeZone("America/Los_Angeles");
+ * 

+ * \htmlonly
\endhtmlonly
+ * You can use the createEnumeration method to iterate through
+ * all the supported time zone IDs, or the getCanonicalID method to check
+ * if a time zone ID is supported or not.  You can then choose a
+ * supported ID to get a TimeZone.
+ * If the time zone you want is not represented by one of the
+ * supported IDs, then you can create a custom time zone ID with
+ * the following syntax:
+ *
+ * \htmlonly
\endhtmlonly
+ * 
+ * GMT[+|-]hh[[:]mm]
+ * 

+ * \htmlonly
\endhtmlonly
+ *
+ * For example, you might specify GMT+14:00 as a custom
+ * time zone ID.  The TimeZone that is returned
+ * when you specify a custom time zone ID uses the specified
+ * offset from GMT(=UTC) and does not observe daylight saving
+ * time. For example, you might specify GMT+14:00 as a custom
+ * time zone ID to create a TimeZone representing 14 hours ahead
+ * of GMT (with no daylight saving time). In addition,
+ * getCanonicalID can also be used to
+ * normalize a custom time zone ID.
+ *
+ * TimeZone is an abstract class representing a time zone.  A TimeZone is needed for
+ * Calendar to produce local time for a particular time zone.  A TimeZone comprises
+ * three basic pieces of information:
+ * 
    
+ *    
  • A time zone offset; that, is the number of milliseconds to add or subtract
+ *      from a time expressed in terms of GMT to convert it to the same time in that
+ *      time zone (without taking daylight savings time into account).
    • 
+ *    
  • Logic necessary to take daylight savings time into account if daylight savings
+ *      time is observed in that time zone (e.g., the days and hours on which daylight
+ *      savings time begins and ends).
    • 
+ *    
  • An ID.  This is a text string that uniquely identifies the time zone.
    • 
+ * 

+ *
+ * (Only the ID is actually implemented in TimeZone; subclasses of TimeZone may handle
+ * daylight savings time and GMT offset in different ways.  Currently we have the following
+ * TimeZone subclasses: RuleBasedTimeZone, SimpleTimeZone, and VTimeZone.)
+ * 

+ * The TimeZone class contains a static list containing a TimeZone object for every
+ * combination of GMT offset and daylight-savings time rules currently in use in the
+ * world, each with a unique ID.  Each ID consists of a region (usually a continent or
+ * ocean) and a city in that region, separated by a slash, (for example, US Pacific
+ * Time is "America/Los_Angeles.")  Because older versions of this class used
+ * three- or four-letter abbreviations instead, there is also a table that maps the older
+ * abbreviations to the newer ones (for example, "PST" maps to "America/Los_Angeles").
+ * Anywhere the API requires an ID, you can use either form.
+ * 

+ * To create a new TimeZone, you call the factory function TimeZone::createTimeZone()
+ * and pass it a time zone ID.  You can use the createEnumeration() function to
+ * obtain a list of all the time zone IDs recognized by createTimeZone().
+ * 

+ * You can also use TimeZone::createDefault() to create a TimeZone.  This function uses
+ * platform-specific APIs to produce a TimeZone for the time zone corresponding to
+ * the client's computer's physical location.  For example, if you're in Japan (assuming
+ * your machine is set up correctly), TimeZone::createDefault() will return a TimeZone
+ * for Japanese Standard Time ("Asia/Tokyo").

Note:The default implementation of

In Java 7, observesDaylightTime() was added in

+     * In general, ICU4C also provides JDK compatible methods, but the current
+     * implementation userDaylightTime() serves the purpose
+     * (takes the current rule into account), observesDaylightTime()
+     * is not added in ICU4C. In addition to useDaylightTime(), ICU4C
+     * BasicTimeZone class (Note that TimeZone::createTimeZone(const UnicodeString &ID)

+/**
+ *
+ * Transliterator is an abstract class that
+ * transliterates text from one format to another.  The most common
+ * kind of transliterator is a script, or alphabet, transliterator.
+ * For example, a Russian to Latin transliterator changes Russian text
+ * written in Cyrillic characters to phonetically equivalent Latin
+ * characters.  It does not translate Russian to English!
+ * Transliteration, unlike translation, operates on characters, without
+ * reference to the meanings of words and sentences.
+ *
+ * 
Although script conversion is its most common use, a
+ * transliterator can actually perform a more general class of tasks.
+ * In fact, Transliterator defines a very general API
+ * which specifies only that a segment of the input text is replaced
+ * by new text.  The particulars of this conversion are determined
+ * entirely by subclasses of Transliterator.
+ *
+ * 
Transliterators are stateless
+ *
+ * 
Transliterator objects are stateless; they
+ * retain no information between calls to
+ * transliterate().  (However, this does not
+ * mean that threads may share transliterators without synchronizing
+ * them.  Transliterators are not immutable, so they must be
+ * synchronized when shared between threads.)  This might seem to
+ * limit the complexity of the transliteration operation.  In
+ * practice, subclasses perform complex transliterations by delaying
+ * the replacement of text until it is known that no other
+ * replacements are possible.  In other words, although the
+ * Transliterator objects are stateless, the source text
+ * itself embodies all the needed information, and delayed operation
+ * allows arbitrary complexity.
+ *
+ * 
Batch transliteration
+ *
+ * 
The simplest way to perform transliteration is all at once, on a
+ * string of existing text.  This is referred to as batch
+ * transliteration.  For example, given a string input
+ * and a transliterator t, the call
+ *
+ *     String result = t.transliterate(input);
+ *
+ * will transliterate it and return the result.  Other methods allow
+ * the client to specify a substring to be transliterated and to use
+ * {@link Replaceable } objects instead of strings, in order to
+ * preserve out-of-band information (such as text styles).
+ *
+ * 
Keyboard transliteration
+ *
+ * 
Somewhat more involved is keyboard, or incremental
+ * transliteration.  This is the transliteration of text that is
+ * arriving from some source (typically the user's keyboard) one
+ * character at a time, or in some other piecemeal fashion.
+ *
+ * 
In keyboard transliteration, a Replaceable buffer
+ * stores the text.  As text is inserted, as much as possible is
+ * transliterated on the fly.  This means a GUI that displays the
+ * contents of the buffer may show text being modified as each new
+ * character arrives.
+ *
+ * 
Consider the simple rule-based Transliterator:
+ * 
+ *     th>{theta}
+ *     t>{tau}
+ * 

+ *
+ * When the user types 't', nothing will happen, since the
+ * transliterator is waiting to see if the next character is 'h'.  To
+ * remedy this, we introduce the notion of a cursor, marked by a '|'
+ * in the output string:
+ * 
+ *     t>|{tau}
+ *     {tau}h>{theta}
+ * 

+ *
+ * Now when the user types 't', tau appears, and if the next character
+ * is 'h', the tau changes to a theta.  This is accomplished by
+ * maintaining a cursor position (independent of the insertion point,
+ * and invisible in the GUI) across calls to
+ * transliterate().  Typically, the cursor will
+ * be coincident with the insertion point, but in a case like the one
+ * above, it will precede the insertion point.
+ *
+ * 
Keyboard transliteration methods maintain a set of three indices
+ * that are updated with each call to
+ * transliterate(), including the cursor, start,
+ * and limit.  Since these indices are changed by the method, they are
+ * passed in an int[] array. The START index
+ * marks the beginning of the substring that the transliterator will
+ * look at.  It is advanced as text becomes committed (but it is not
+ * the committed index; that's the CURSOR).  The
+ * CURSOR index, described above, marks the point at
+ * which the transliterator last stopped, either because it reached
+ * the end, or because it required more characters to disambiguate
+ * between possible inputs.  The CURSOR can also be
+ * explicitly set by rules in a rule-based Transliterator.
+ * Any characters before the CURSOR index are frozen;
+ * future keyboard transliteration calls within this input sequence
+ * will not change them.  New text is inserted at the
+ * LIMIT index, which marks the end of the substring that
+ * the transliterator looks at.
+ *
+ * 
Because keyboard transliteration assumes that more characters
+ * are to arrive, it is conservative in its operation.  It only
+ * transliterates when it can do so unambiguously.  Otherwise it waits
+ * for more characters to arrive.  When the client code knows that no
+ * more characters are forthcoming, perhaps because the user has
+ * performed some input termination operation, then it should call
+ * finishTransliteration() to complete any
+ * pending transliterations.
+ *
+ * 
Inverses
+ *
+ * 
Pairs of transliterators may be inverses of one another.  For
+ * example, if transliterator A transliterates characters by
+ * incrementing their Unicode value (so "abc" -> "def"), and
+ * transliterator B decrements character values, then A
+ * is an inverse of B and vice versa.  If we compose A
+ * with B in a compound transliterator, the result is the
+ * identity transliterator, that is, a transliterator that does not
+ * change its input text.
+ *
+ * The Transliterator method getInverse()
+ * returns a transliterator's inverse, if one exists, or
+ * null otherwise.  However, the result of
+ * getInverse() usually will not be a true
+ * mathematical inverse.  This is because true inverse transliterators
+ * are difficult to formulate.  For example, consider two
+ * transliterators: AB, which transliterates the character 'A'
+ * to 'B', and BA, which transliterates 'B' to 'A'.  It might
+ * seem that these are exact inverses, since
+ *
+ * \htmlonly
\endhtmlonly"A" x AB -> "B"

+ * "B" x BA -> "A"\htmlonly
\endhtmlonly
+ *
+ * where 'x' represents transliteration.  However,
+ *
+ * \htmlonly
\endhtmlonly"ABCD" x AB -> "BBCD"

+ * "BBCD" x BA -> "AACD"\htmlonly
\endhtmlonly
+ *
+ * so AB composed with BA is not the
+ * identity. Nonetheless, BA may be usefully considered to be
+ * AB's inverse, and it is on this basis that
+ * AB.getInverse() could legitimately return
+ * BA.
+ *
+ * 
IDs and display names
+ *
+ * 
A transliterator is designated by a short identifier string or
+ * ID.  IDs follow the format source-destination,
+ * where source describes the entity being replaced, and
+ * destination describes the entity replacing
+ * source.  The entities may be the names of scripts,
+ * particular sequences of characters, or whatever else it is that the
+ * transliterator converts to or from.  For example, a transliterator
+ * from Russian to Latin might be named "Russian-Latin".  A
+ * transliterator from keyboard escape sequences to Latin-1 characters
+ * might be named "KeyboardEscape-Latin1".  By convention, system
+ * entity names are in English, with the initial letters of words
+ * capitalized; user entity names may follow any format so long as
+ * they do not contain dashes.
+ *
+ * 
In addition to programmatic IDs, transliterator objects have
+ * display names for presentation in user interfaces, returned by
+ * {@link #getDisplayName }.
+ *
+ * 
Factory methods and registration
+ *
+ * 
In general, client code should use the factory method
+ * {@link #createInstance } to obtain an instance of a
+ * transliterator given its ID.  Valid IDs may be enumerated using
+ * getAvailableIDs().  Since transliterators are mutable,
+ * multiple calls to {@link #createInstance } with the same ID will
+ * return distinct objects.
+ *
+ * 
In addition to the system transliterators registered at startup,
+ * user transliterators may be registered by calling
+ * registerInstance() at run time.  A registered instance
+ * acts a template; future calls to {@link #createInstance } with the ID
+ * of the registered object return clones of that object.  Thus any
+ * object passed to registerInstance() must implement
+ * clone() properly.  To register a transliterator subclass
+ * without instantiating it (until it is needed), users may call
+ * {@link #registerFactory }.  In this case, the objects are
+ * instantiated by invoking the zero-argument public constructor of
+ * the class.
+ *
+ * 
Subclassing
+ *
+ * Subclasses must implement the abstract method
+ * handleTransliterate().  
Subclasses should override
+ * the transliterate() method taking a
+ * Replaceable and the transliterate()
+ * method taking a String and StringBuffer
+ * if the performance of these methods can be improved over the
+ * performance obtained by the default implementations in this class.
+ *
+ * 
Rule syntax
+ *
+ * 
A set of rules determines how to perform translations.
+ * Rules within a rule set are separated by semicolons (';').
+ * To include a literal semicolon, prefix it with a backslash ('\').
+ * Unicode Pattern_White_Space is ignored.
+ * If the first non-blank character on a line is '#',
+ * the entire line is ignored as a comment.
+ *
+ * 
Each set of rules consists of two groups, one forward, and one
+ * reverse. This is a convention that is not enforced; rules for one
+ * direction may be omitted, with the result that translations in
+ * that direction will not modify the source text. In addition,
+ * bidirectional forward-reverse rules may be specified for
+ * symmetrical transformations.
+ *
+ * 
Note: Another description of the Transliterator rule syntax is available in
+ * section
+ * Transform Rules Syntax of UTS #35: Unicode LDML.
+ * The rules are shown there using arrow symbols ← and → and ↔.
+ * ICU supports both those and the equivalent ASCII symbols < and > and <>.
+ *
+ * 
Rule statements take one of the following forms:
+ *
+ * 

+ *     
$alefmadda=\\u0622;

+ *     
Variable definition. The name on the
+ *         left is assigned the text on the right. In this example,
+ *         after this statement, instances of the left hand name,
+ *         "$alefmadda", will be replaced by
+ *         the Unicode character U+0622. Variable names must begin
+ *         with a letter and consist only of letters, digits, and
+ *         underscores. Case is significant. Duplicate names cause
+ *         an exception to be thrown, that is, variables cannot be
+ *         redefined. The right hand side may contain well-formed
+ *         text of any length, including no text at all ("$empty=;").
+ *         The right hand side may contain embedded UnicodeSet
+ *         patterns, for example, "$softvowel=[eiyEIY]".

+ *     
ai>$alefmadda;

+ *     
Forward translation rule. This rule
+ *         states that the string on the left will be changed to the
+ *         string on the right when performing forward
+ *         transliteration.

+ *     
ai<$alefmadda;

+ *     
Reverse translation rule. This rule
+ *         states that the string on the right will be changed to
+ *         the string on the left when performing reverse
+ *         transliteration.

+ * 

+ *
+ * 

+ *     
ai<>$alefmadda;

+ *     
Bidirectional translation rule. This
+ *         rule states that the string on the right will be changed
+ *         to the string on the left when performing forward
+ *         transliteration, and vice versa when performing reverse
+ *         transliteration.

+ * 

+ *
+ * 
Translation rules consist of a match pattern and an output
+ * string. The match pattern consists of literal characters,
+ * optionally preceded by context, and optionally followed by
+ * context. Context characters, like literal pattern characters,
+ * must be matched in the text being transliterated. However, unlike
+ * literal pattern characters, they are not replaced by the output
+ * text. For example, the pattern "abc{def}"
+ * indicates the characters "def" must be
+ * preceded by "abc" for a successful match.
+ * If there is a successful match, "def" will
+ * be replaced, but not "abc". The final '}'
+ * is optional, so "abc{def" is equivalent to
+ * "abc{def}". Another example is "{123}456"
+ * (or "123}456") in which the literal
+ * pattern "123" must be followed by "456".
+ *
+ * 
The output string of a forward or reverse rule consists of
+ * characters to replace the literal pattern characters. If the
+ * output string contains the character '|', this is
+ * taken to indicate the location of the cursor after
+ * replacement. The cursor is the point in the text at which the
+ * next replacement, if any, will be applied. The cursor is usually
+ * placed within the replacement text; however, it can actually be
+ * placed into the preceding or following context by using the
+ * special character '@'. Examples:
+ *
+ * 
+ *     a {foo} z > | @ bar; # foo -> bar, move cursor before a
+ *     {foo} xyz > bar @@|; # foo -> bar, cursor between y and z
+ * 

+ *
+ * 
UnicodeSet
+ *
+ * 
UnicodeSet patterns may appear anywhere that
+ * makes sense. They may appear in variable definitions.
+ * Contrariwise, UnicodeSet patterns may themselves
+ * contain variable references, such as "$a=[a-z];$not_a=[^$a]",
+ * or "$range=a-z;$ll=[$range]".
+ *
+ * 
UnicodeSet patterns may also be embedded directly
+ * into rule strings. Thus, the following two rules are equivalent:
+ *
+ * 
+ *     $vowel=[aeiou]; $vowel>'*'; # One way to do this
+ *     [aeiou]>'*'; # Another way
+ * 

+ *
+ * 
See {@link UnicodeSet} for more documentation and examples.
+ *
+ * 
Segments
+ *
+ * 
Segments of the input string can be matched and copied to the
+ * output string. This makes certain sets of rules simpler and more
+ * general, and makes reordering possible. For example:
+ *
+ * 
+ *     ([a-z]) > $1 $1; # double lowercase letters
+ *     ([:Lu:]) ([:Ll:]) > $2 $1; # reverse order of Lu-Ll pairs
+ * 

+ *
+ * 
The segment of the input string to be copied is delimited by
+ * "(" and ")". Up to
+ * nine segments may be defined. Segments may not overlap. In the
+ * output string, "$1" through "$9"
+ * represent the input string segments, in left-to-right order of
+ * definition.
+ *
+ * 
Anchors
+ *
+ * 
Patterns can be anchored to the beginning or the end of the text. This is done with the
+ * special characters '^' and '$'. For example:
+ *
+ * 
+ *   ^ a   > 'BEG_A';   # match 'a' at start of text
+ *     a   > 'A'; # match other instances of 'a'
+ *     z $ > 'END_Z';   # match 'z' at end of text
+ *     z   > 'Z';       # match other instances of 'z'
+ * 

+ *
+ * 
It is also possible to match the beginning or the end of the text using a UnicodeSet.
+ * This is done by including a virtual anchor character '$' at the end of the
+ * set pattern. Although this is usually the match character for the end anchor, the set will
+ * match either the beginning or the end of the text, depending on its placement. For
+ * example:
+ *
+ * 
+ *   $x = [a-z$];   # match 'a' through 'z' OR anchor
+ *   $x 1    > 2;   # match '1' after a-z or at the start
+ *      3 $x > 4;   # match '3' before a-z or at the end
+ * 

+ *
+ * 
Example
+ *
+ * 
The following example rules illustrate many of the features of
+ * the rule language.
+ *
+ * 
+ *     
+ *         
+ *         
+ *     
+ *     
+ *         
+ *         
+ *     
+ *     
+ *         
+ *         
+ *     
+ * 
Rule 1.abc{def}>x|y
Rule 2.xyz>r
Rule 3.yz>q

+ *
+ * 
Applying these rules to the string "adefabcdefz"
+ * yields the following results:
+ *
+ * 
+ *     
+ *         
+ *         
+ *     
+ *     
+ *         
+ *         
+ *     
+ *     
+ *         
+ *

+ *

+ *

+ *         
+ *         
+ *     
+ *     
+ *         
+ *         
+ *     
+ *     
+ *         
+ *         
+ *     
+ *     
+ *         
+ *         
+ *     
+ *     
+ *         
+ *         
+ *     
+ *     
+ *         
+ *         
+ *     
+ * 
|adefabcdefzInitial state, no rules match. Advance
+ *         cursor.
a|defabcdefzStill no match. Rule 1 does not match
+ *         because the preceding context is not present.
ad|efabcdefzStill no match. Keep advancing until
+ *         there is a match...
ade|fabcdefz...
adef|abcdefz...
adefa|bcdefz...
adefab|cdefz...
adefabc|defzRule 1 matches; replace "def"
+ *         with "xy" and back up the cursor
+ *         to before the 'y'.
adefabcx|yzAlthough "xyz" is
+ *         present, rule 2 does not match because the cursor is
+ *         before the 'y', not before the 'x'.
+ *         Rule 3 does match. Replace "yz"
+ *         with "q".
adefabcxq|The cursor is at the end;
+ *         transliteration is complete.

+ *
+ * 
The order of rules is significant. If multiple rules may match
+ * at some point, the first matching rule is applied.
+ *
+ * 
Forward and reverse rules may have an empty output string.
+ * Otherwise, an empty left or right hand side of any statement is a
+ * syntax error.
+ *
+ * 
Single quotes are used to quote any character other than a
+ * digit or letter. To specify a single quote itself, inside or
+ * outside of quotes, use two single quotes in a row. For example,
+ * the rule "'>'>o''clock" changes the
+ * string ">" to the string "o'clock".
+ *
+ * 
Notes
+ *
+ * 
While a Transliterator is being built from rules, it checks that
+ * the rules are added in proper order. For example, if the rule
+ * "a>x" is followed by the rule "ab>y",
+ * then the second rule will throw an exception. The reason is that
+ * the second rule can never be triggered, since the first rule
+ * always matches anything it matches. In other words, the first
+ * rule masks the second rule.

    • 
+     *
+     *  
  • Text before originalStart and text after
+     *  pos.limit should not change.

+     *
+     *  
  • Text before pos.contextStart and text after
+     *   pos.contextLimit should be ignored.

+     * 

+     *

+ * by multiple time zones. Also a time zone may have multiple meta zone historic mappings.
+ * 

+ * For example, people in the United States refer the zone used by the east part of North America as "Eastern Time".
+ * The tz database contains multiple time zones "America/New_York", "America/Detroit", "America/Montreal" and some
+ * others that belong to "Eastern Time". However, assigning different display names to these time zones does not make
+ * much sense for most of people.
+ * 

+ * In CLDR (which uses LDML for representing locale data), the display name
+ * "Eastern Time" is stored as long generic display name of a meta zone identified by the ID "America_Eastern".
+ * Then, there is another table maintaining the historic mapping to meta zones for each time zone. The time zones in
+ * the above example ("America/New_York", "America/Detroit"...) are mapped to the meta zone "America_Eastern".
+ * 

+ * Sometimes, a time zone is mapped to a different time zone in the past. For example, "America/Indiana/Knox"
+ * had been moving "Eastern Time" and "Central Time" back and forth. Therefore, it is necessary that time zone
+ * to meta zones mapping data are stored by date range.
+ *
+ * 
Note:
+ * The methods in this class assume that time zone IDs are already canonicalized. For example, you may not get proper
+ * result returned by a method with time zone ID "America/Indiana/Indianapolis", because it's not a canonical time zone
+ * ID (the canonical time zone ID for the time zone is "America/Indianapolis". See
+ * {@link TimeZone#getCanonicalID(const UnicodeString& id, UnicodeString& canonicalID, UErrorCode& status)} about ICU
+ * canonical time zone IDs.
+ *
+ * 

+ * In CLDR, most of time zone display names except location names are provided through meta zones. But a time zone may
+ * have a specific name that is not shared with other time zones.
+ *
+ * For example, time zone "Europe/London" has English long name for standard time "Greenwich Mean Time", which is also
+ * shared with other time zones. However, the long name for daylight saving time is "British Summer Time", which is only
+ * used for "Europe/London".
+ *
+ * 

+ * {@link #getTimeZoneDisplayName} is designed for accessing a name only used by a single time zone.
+ * But is not necessarily mean that a subclass implementation use the same model with CLDR. A subclass implementation
+ * may provide time zone names only through {@link #getTimeZoneDisplayName}, or only through {@link #getMetaZoneDisplayName},
+ * or both.
+ *
+ * 

+ * The default TimeZoneNames implementation returned by {@link #createInstance}
+ * uses the locale data imported from CLDR. In CLDR, set of meta zone IDs and mappings between zone IDs and meta zone
+ * IDs are shared by all locales. Therefore, the behavior of {@link #getAvailableMetaZoneIDs},
+ * {@link #getMetaZoneID}, and {@link #getReferenceZoneID} won't be changed no matter
+ * what locale is used for getting an instance of TimeZoneNames.

+ *
+ * 
Bidi algorithm for ICU

+ *
+ * This is an implementation of the Unicode Bidirectional Algorithm.
+ * The algorithm is defined in the
+ * Unicode Standard Annex #9.

+ *
+ * Note: Libraries that perform a bidirectional algorithm and
+ * reorder strings accordingly are sometimes called "Storage Layout Engines".
+ * ICU's Bidi and shaping (u_shapeArabic()) APIs can be used at the core of such
+ * "Storage Layout Engines".
+ *
+ * 
General remarks about the API:

+ *
+ * In functions with an error code parameter,
+ * the pErrorCode pointer must be valid
+ * and the value that it points to must not indicate a failure before
+ * the function call. Otherwise, the function returns immediately.
+ * After the function call, the value indicates success or failure.

+ *
+ * The "limit" of a sequence of characters is the position just after their
+ * last character, i.e., one more than that position.

+ *
+ * Some of the API functions provide access to "runs".
+ * Such a "run" is defined as a sequence of characters
+ * that are at the same embedding level
+ * after performing the Bidi algorithm.

+ *
+ * @author Markus W. Scherer
+ * @version 1.0
+ *
+ *
+ * 
 Sample code for the ICU Bidi API 

+ *
+ * 
Rendering a paragraph with the ICU Bidi API

+ *
+ * This is (hypothetical) sample code that illustrates
+ * how the ICU Bidi API could be used to render a paragraph of text.
+ * Rendering code depends highly on the graphics system,
+ * therefore this sample code must make a lot of assumptions,
+ * which may or may not match any existing graphics system's properties.
+ *
+ * 
The basic assumptions are:

+ * 
    
+ * 
  • Rendering is done from left to right on a horizontal line.
    • 
+ * 
  • A run of single-style, unidirectional text can be rendered at once.
    • 
+ * 
  • Such a run of text is passed to the graphics system with
+ *     characters (code units) in logical order.
    • 
+ * 
  • The line-breaking algorithm is very complicated
+ *     and Locale-dependent -
+ *     and therefore its implementation omitted from this sample code.
    • 
+ *

+/**
+ * Modify the operation of the Bidi algorithm such that it implements some
+ * variant to the basic Bidi algorithm or approximates an "inverse Bidi"
+ * algorithm, depending on different values of the "reordering mode".
+ * This function must be called before ubidi_setPara(), and stays
+ * in effect until called again with a different argument.
+ *
+ * 
The normal operation of the Bidi algorithm as described
+ * in the Unicode Standard Annex #9 is to take text stored in logical
+ * (keyboard, typing) order and to determine how to reorder it for visual
+ * rendering.

+ *
+ * 
With the reordering mode set to a value other than
+ * #UBIDI_REORDER_DEFAULT, this function changes the behavior of
+ * some of the subsequent functions in a way such that they implement an
+ * inverse Bidi algorithm or some other algorithm variants.

+ *
+ * 
Some legacy systems store text in visual order, and for operations
+ * with standard, Unicode-based algorithms, the text needs to be transformed
+ * into logical order. This is effectively the inverse algorithm of the
+ * described Bidi algorithm. Note that there is no standard algorithm for
+ * this "inverse Bidi", so a number of variants are implemented here.

+ *
+ * 
In other cases, it may be desirable to emulate some variant of the
+ * Logical to Visual algorithm (e.g. one used in MS Windows), or perform a
+ * Logical to Logical transformation.

+ *
+ * 
    
+ * 
  • When the reordering mode is set to #UBIDI_REORDER_DEFAULT,
+ * the standard Bidi Logical to Visual algorithm is applied.
    • 
+ *
+ * 
  • When the reordering mode is set to
+ * #UBIDI_REORDER_NUMBERS_SPECIAL,
+ * the algorithm used to perform Bidi transformations when calling
+ * ubidi_setPara should approximate the algorithm used in
+ * Microsoft Windows XP rather than strictly conform to the Unicode Bidi
+ * algorithm.
+ * 
    
+ * The differences between the basic algorithm and the algorithm addressed
+ * by this option are as follows:
+ * 
      
+ *   
    • Within text at an even embedding level, the sequence "123AB"
+ *   (where AB represent R or AL letters) is transformed to "123BA" by the
+ *   Unicode algorithm and to "BA123" by the Windows algorithm.
      • 
+ *   
    • Arabic-Indic numbers (AN) are handled by the Windows algorithm just
+ *   like regular numbers (EN).
      • 
+ * 
    • 
+ *
+ * 
  • When the reordering mode is set to
+ * #UBIDI_REORDER_GROUP_NUMBERS_WITH_R,
+ * numbers located between LTR text and RTL text are associated with the RTL
+ * text. For instance, an LTR paragraph with content "abc 123 DEF" (where
+ * upper case letters represent RTL characters) will be transformed to
+ * "abc FED 123" (and not "abc 123 FED"), "DEF 123 abc" will be transformed
+ * to "123 FED abc" and "123 FED abc" will be transformed to "DEF 123 abc".
+ * This makes the algorithm reversible and makes it useful when round trip
+ * (from visual to logical and back to visual) must be achieved without
+ * adding LRM characters. However, this is a variation from the standard
+ * Unicode Bidi algorithm.
    
+ * The source text should not contain Bidi control characters other than LRM
+ * or RLM.
    • 
+ *
+ * 
  • When the reordering mode is set to
+ * #UBIDI_REORDER_RUNS_ONLY,
+ * a "Logical to Logical" transformation must be performed:
+ * 
      
+ * 
    • If the default text level of the source text (argument paraLevel
+ * in ubidi_setPara) is even, the source text will be handled as
+ * LTR logical text and will be transformed to the RTL logical text which has
+ * the same LTR visual display.
      • 
+ * 
    • If the default level of the source text is odd, the source text
+ * will be handled as RTL logical text and will be transformed to the
+ * LTR logical text which has the same LTR visual display.
      • 
+ * 
    
+ * This mode may be needed when logical text which is basically Arabic or
+ * Hebrew, with possible included numbers or phrases in English, has to be
+ * displayed as if it had an even embedding level (this can happen if the
+ * displaying application treats all text as if it was basically LTR).
+ * 
    
+ * This mode may also be needed in the reverse case, when logical text which is
+ * basically English, with possible included phrases in Arabic or Hebrew, has to
+ * be displayed as if it had an odd embedding level.
+ * 
    
+ * Both cases could be handled by adding LRE or RLE at the head of the text,
+ * if the display subsystem supports these formatting controls. If it does not,
+ * the problem may be handled by transforming the source text in this mode
+ * before displaying it, so that it will be displayed properly.
    
+ * The source text should not contain Bidi control characters other than LRM
+ * or RLM.
    • 
+ *
+ * 
  • When the reordering mode is set to
+ * #UBIDI_REORDER_INVERSE_NUMBERS_AS_L, an "inverse Bidi" algorithm
+ * is applied.
+ * Runs of text with numeric characters will be treated like LTR letters and
+ * may need to be surrounded with LRM characters when they are written in
+ * reordered sequence (the option #UBIDI_INSERT_LRM_FOR_NUMERIC can
+ * be used with function ubidi_writeReordered to this end. This
+ * mode is equivalent to calling ubidi_setInverse() with
+ * argument isInverse set to true.
    • 
+ *
+ * 
  • When the reordering mode is set to
+ * #UBIDI_REORDER_INVERSE_LIKE_DIRECT, the "direct" Logical to Visual
+ * Bidi algorithm is used as an approximation of an "inverse Bidi" algorithm.
+ * This mode is similar to mode #UBIDI_REORDER_INVERSE_NUMBERS_AS_L
+ * but is closer to the regular Bidi algorithm.
+ * 
    
+ * For example, an LTR paragraph with the content "FED 123 456 CBA" (where
+ * upper case represents RTL characters) will be transformed to
+ * "ABC 456 123 DEF", as opposed to "DEF 123 456 ABC"
+ * with mode UBIDI_REORDER_INVERSE_NUMBERS_AS_L.
    
+ * When used in conjunction with option
+ * #UBIDI_OPTION_INSERT_MARKS, this mode generally
+ * adds Bidi marks to the output significantly more sparingly than mode
+ * #UBIDI_REORDER_INVERSE_NUMBERS_AS_L with option
+ * #UBIDI_INSERT_LRM_FOR_NUMERIC in calls to
+ * ubidi_writeReordered.
    • 
+ *
+ * 
  • When the reordering mode is set to
+ * #UBIDI_REORDER_INVERSE_FOR_NUMBERS_SPECIAL, the Logical to Visual
+ * Bidi algorithm used in Windows XP is used as an approximation of an "inverse Bidi" algorithm.
+ * 
    
+ * For example, an LTR paragraph with the content "abc FED123" (where
+ * upper case represents RTL characters) will be transformed to "abc 123DEF."
    • 
+ * 

+ *
+ * 
In all the reordering modes specifying an "inverse Bidi" algorithm
+ * (i.e. those with a name starting with UBIDI_REORDER_INVERSE),
+ * output runs should be retrieved using
+ * ubidi_getVisualRun(), and the output text with
+ * ubidi_writeReordered(). The caller should keep in mind that in
+ * "inverse Bidi" modes the input is actually visually ordered text and
+ * reordered output returned by ubidi_getVisualRun() or
+ * ubidi_writeReordered() are actually runs or character string
+ * of logically ordered output.

+ * For all the "inverse Bidi" modes, the source text should not contain
+ * Bidi control characters other than LRM or RLM.

+ *
+ * 
Note that option #UBIDI_OUTPUT_REVERSE of
+ * ubidi_writeReordered has no useful meaning and should not be

+ * Perform the Unicode Bidi algorithm. It is defined in the

+ *
+ * This function takes a piece of plain text containing one or more paragraphs,
+ * with or without externally specified embedding levels from styled
+ * text and computes the left-right-directionality of each character.

+ *
+ * If the entire text is all of the same directionality, then
+ * the function may not perform all the steps described by the algorithm,
+ * i.e., some levels may not be the same as if all steps were performed.
+ * This is not relevant for unidirectional text.

+ * For example, in pure LTR text with numbers the numbers would get
+ * a resolved level of 2 higher than the surrounding text according to
+ * the algorithm. This implementation may set all resolved levels to
+ * the same value in such a case.

+ *
+ * The text can be composed of multiple paragraphs. Occurrence of a block
+ * separator in the text terminates a paragraph, and whatever comes next starts
+ * a new paragraph. The exception to this rule is when a Carriage Return (CR)
+ * is followed by a Line Feed (LF). Both CR and LF are block separators, but
+ * in that case, the pair of characters is considered as terminating the
+ * preceding paragraph, and a new paragraph will be started by a character
+ * coming after the LF.
+ *
+ * @param pBiDi A UBiDi object allocated with ubidi_open()
+ *        which will be set to contain the reordering information,
+ *        especially the resolved levels for all the characters in text.
+ *
+ * @param text is a pointer to the text that the Bidi algorithm will be performed on.
+ *        This pointer is stored in the UBiDi object and can be retrieved
+ *        with ubidi_getText().

+ *        Note: the text must be (at least) length long.
+ *
+ * @param length is the length of the text; if length==-1 then
+ *        the text must be zero-terminated.
+ *
+ * @param paraLevel specifies the default level for the text;
+ *        it is typically 0 (LTR) or 1 (RTL).
+ *        If the function shall determine the paragraph level from the text,
+ *        then paraLevel can be set to
+ *        either #UBIDI_DEFAULT_LTR
+ *        or #UBIDI_DEFAULT_RTL; if the text contains multiple
+ *        paragraphs, the paragraph level shall be determined separately for
+ *        each paragraph; if a paragraph does not include any strongly typed
+ *        character, then the desired default is used (0 for LTR or 1 for RTL).
+ *        Any other value between 0 and #UBIDI_MAX_EXPLICIT_LEVEL
+ *        is also valid, with odd levels indicating RTL.
+ *
+ * @param embeddingLevels (in) may be used to preset the embedding and override levels,
+ *        ignoring characters like LRE and PDF in the text.
+ *        A level overrides the directional property of its corresponding
+ *        (same index) character if the level has the
+ *        #UBIDI_LEVEL_OVERRIDE bit set.


+ *        Aside from that bit, it must be
+ *        paraLevel<=embeddingLevels[]<=UBIDI_MAX_EXPLICIT_LEVEL,
+ *        except that level 0 is always allowed.
+ *        Level 0 for a paragraph separator prevents reordering of paragraphs;
+ *        this only works reliably if #UBIDI_LEVEL_OVERRIDE
+ *        is also set for paragraph separators.
+ *        Level 0 for other characters is treated as a wildcard
+ *        and is lifted up to the resolved level of the surrounding paragraph.


+ *        Caution: A copy of this pointer, not of the levels,
+ *        will be stored in the UBiDi object;
+ *        the embeddingLevels array must not be
+ *        deallocated before the UBiDi structure is destroyed or reused,
+ *        and the embeddingLevels
+ *        should not be modified to avoid unexpected results on subsequent Bidi operations.

+ *     reversing a visual LTR string,
+ *
+ *   - : unless the input direction is RTL, this
+ *     corresponds to an "inverse bidi algorithm" in `UBiDi` with the
+ *     reordering mode set to `UBIDI_REORDER_INVERSE_LIKE_DIRECT`.
+ *     Visual RTL mode is not not supported by `UBiDi` and is
+ *     accomplished through reversing a visual LTR string,
+ *
+ *   - : if the input and output base directions
+ *     mismatch, this corresponds to the `UBiDi` implementation with the
+ *     reordering mode set to `UBIDI_REORDER_RUNS_ONLY`; and if the
+ *     input and output base directions are identical, the transformation engine
+ *     will only handle character mirroring and Arabic shaping operations without
+ *     reordering,
+ *
+ *   - : this reordering mode is not supported by
+ *     the `UBiDi` engine; it implies character mirroring, Arabic
+ *     shaping, and - if the input/output base directions mismatch -  string
+ *     reverse operations.

+ * Performs transformation of text from the bidi layout defined by the input

+ * In terms of UBiDi, such a transformation implies:
+ * 
    
+ * 
  • calling ubidi_setReorderingMode as needed (when the
+ * reordering mode is other than normal),
    • 
+ * 
  • calling ubidi_setInverse as needed (when text should be

    • 
+ * 
  • resolving embedding levels of each character in the input text by
+ * calling ubidi_setPara,
    • 
+ * 
  • reordering the characters based on the computed embedding levels, also
+ * performing character mirroring as needed, and streaming the result to the
+ * output, by calling ubidi_writeReordered,
    • 
+ * 
  • performing Arabic digit and letter shaping on the output text by calling
+ * u_shapeArabic.
    • 
+ * 

+ * An "ordering scheme" encompasses the base direction and the order of text,
+ * and these characteristics must be defined by the caller for both input and
+ * output explicitly .

+ * There are 36 possible combinations of  ordering schemes,
+ * which are partially supported by UBiDi already. Examples of the
+ * currently supported combinations:
+ * 
    
+ * 
  • : this is equivalent to calling
+ * ubidi_setPara with paraLevel == UBIDI_LTR,
    • 
+ * 
  • : this is equivalent to calling
+ * ubidi_setPara with paraLevel == UBIDI_RTL,
    • 
+ * 
  • : this is equivalent to
+ * calling ubidi_setPara with
+ * paraLevel == UBIDI_DEFAULT_LTR,
    • 
+ * 
  • : this is equivalent to
+ * calling ubidi_setPara with
+ * paraLevel == UBIDI_DEFAULT_RTL,
    • 
+ * 
  • : this is equivalent to
+ * calling ubidi_setInverse(UBiDi*, true) and then
+ * ubidi_setPara with paraLevel == UBIDI_LTR,
    • 
+ * 
  • : this is equivalent to
+ * calling ubidi_setInverse(UBiDi*, true) and then
+ * ubidi_setPara with paraLevel == UBIDI_RTL.
    • 
+ *

+ * 

+ * 

+ *
+ * @param pBiDiTransform A pointer to a UBiDiTransform object
+ *        allocated with ubiditransform_open() or
+ *        NULL.

+ *        This object serves for one-time setup to amortize initialization
+ *        overheads. Use of this object is not thread-safe. All other threads
+ *        should allocate a new UBiDiTransform object by calling
+ *        ubiditransform_open() before using it. Alternatively,
+ *        a caller can set this parameter to NULL, in which case
+ *        the object will be allocated by the engine on the fly.

+ * @param src A pointer to the text that the Bidi layout transformations will
+ *        be performed on.
+ *        
Note: the text must be (at least)
+ *        srcLength long.

+ * @param srcLength The length of the text, in number of UChars. If
+ *        length == -1 then the text must be zero-terminated.
+ * @param dest A pointer to where the processed text is to be copied.
+ * @param destSize The size of the dest buffer, in number of
+ *        UChars. If the U_SHAPE_LETTERS_UNSHAPE option is set,
+ *        then the destination length could be as large as
+ *        srcLength * 2. Otherwise, the destination length will
+ *        not exceed srcLength. If the caller reserves the last
+ *        position for zero-termination, it should be excluded from
+ *        destSize.
+ *        
destSize == -1 is allowed and makes sense when
+ *        dest was holds some meaningful value, e.g. that of
+ *        src. In this case dest must be
+ *        zero-terminated.

+ * @param inParaLevel A base embedding level of the input as defined in
+ *        ubidi_setPara documentation for the
+ *        paraLevel parameter.
+ * @param inOrder An order of the input, which can be one of the
+ *        UBiDiOrder values.
+ * @param outParaLevel A base embedding level of the output as defined in
+ *        ubidi_setPara documentation for the
+ *        paraLevel parameter.
+ * @param outOrder An order of the output, which can be one of the
+ *        UBiDiOrder values.
+ * @param doMirroring Indicates whether or not to perform character mirroring,
+ *        and can accept one of the UBiDiMirroring values.
+ * @param shapingOptions Arabic digit and letter shaping options defined in the
+ *        ushape.h documentation.
+ *        
Note: Direction indicator options are computed by
+ *        the transformation engine based on the effective ordering schemes, so
+ *        user-defined direction indicators will be ignored.

+ * @param pErrorCode A pointer to an error code value.
+ *
+ * @return The destination length, i.e. the number of UChars written to
+ *         dest. If the transformation fails, the return value
+ *         will be 0 (and the error code will be written to

+ *
+ * 
 BreakIterator C API 

+ *
+ * The BreakIterator C API defines  methods for finding the location
+ * of boundaries in text. Pointer to a UBreakIterator maintain a
+ * current position and scan over text returning the index of characters
+ * where boundaries occur.
+ * 

+ * Line boundary analysis determines where a text string can be broken
+ * when line-wrapping. The mechanism correctly handles punctuation and
+ * hyphenated words.
+ * 

+ * Note: The locale keyword "lb" can be used to modify line break
+ * behavior according to the CSS level 3 line-break options, see
+ * . For example:
+ * "ja@lb=strict", "zh@lb=loose".
+ * 

+ * Sentence boundary analysis allows selection with correct
+ * interpretation of periods within numbers and abbreviations, and
+ * trailing punctuation marks such as quotation marks and parentheses.
+ * 

+ * Note: The locale keyword "ss" can be used to enable use of
+ * segmentation suppression data (preventing breaks in English after
+ * abbreviations such as "Mr." or "Est.", for example), as follows:
+ * "en@ss=standard".
+ * 

+ * Word boundary analysis is used by search and replace functions, as
+ * well as within text editing applications that allow the user to
+ * select words with a double click. Word selection provides correct
+ * interpretation of punctuation marks within and following
+ * words. Characters that are not part of a word, such as symbols or
+ * punctuation marks, have word-breaks on both sides.
+ * 

+ * Character boundary analysis identifies the boundaries of
+ * "Extended Grapheme Clusters", which are groupings of codepoints
+ * that should be treated as character-like units for many text operations.
+ * Please see Unicode Standard Annex #29, Unicode Text Segmentation,
+ * http://www.unicode.org/reports/tr29/ for additional information
+ * on grapheme clusters and guidelines on their use.
+ * 

+ * Title boundary analysis locates all positions,
+ * typically starts of words, that should be set to Title Case
+ * when title casing the text.
+ * 

+ * The text boundary positions are found according to the rules
+ * described in Unicode Standard Annex #29, Text Boundaries, and
+ * Unicode Standard Annex #14, Line Breaking Properties.  These
+ * are available at http://www.unicode.org/reports/tr14/ and
+ * http://www.unicode.org/reports/tr29/.
+ * 

+ * In addition to the plain C API defined in this header file, an
+ * object oriented C++ API with equivalent functionality is defined in the
+ * file brkiter.h.
+ * 

+ * Code snippets illustrating the use of the Break Iterator APIs
+ * are available in the ICU User Guide,
+ * https://unicode-org.github.io/icu/userguide/boundaryanalysis/
+ * and in the sample program icu/source/samples/break/break.cpp

Calendar C API

+ *
+ * UCalendar C API is used  for converting between a UDate object
+ * and a set of integer fields such as UCAL_YEAR, UCAL_MONTH,
+ * UCAL_DAY, UCAL_HOUR, and so on.
+ * (A UDate object represents a specific instant in
+ * time with millisecond precision. See UDate
+ * for information about the UDate .)
+ *
+ * 

+ * Types of UCalendar interpret a UDate
+ * according to the rules of a specific calendar system. The C API
+ * provides the enum UCalendarType with UCAL_TRADITIONAL and
+ * UCAL_GREGORIAN.
+ * 

+ * Like other locale-sensitive C API, calendar API  provides a
+ * function, ucal_open(), which returns a pointer to
+ * UCalendar whose time fields have been initialized
+ * with the current date and time. We need to specify the type of
+ * calendar to be opened and the  timezoneId.
+ * \htmlonly
\endhtmlonly
+ * 
+ * \code
+ * UCalendar *caldef;
+ * UChar *tzId;
+ * UErrorCode status;
+ * tzId=(UChar*)malloc(sizeof(UChar) * (strlen("PST") +1) );
+ * u_uastrcpy(tzId, "PST");
+ * caldef=ucal_open(tzID, u_strlen(tzID), NULL, UCAL_TRADITIONAL, &status);
+ * \endcode
+ * 

+ * \htmlonly
\endhtmlonly
+ *
+ * 

+ * A UCalendar object can produce all the time field values
+ * needed to implement the date-time formatting for a particular language
+ * and calendar style (for example, Japanese-Gregorian, Japanese-Traditional).
+ *
+ * 

+ * When computing a UDate from time fields, two special circumstances
+ * may arise: there may be insufficient information to compute the
+ * UDate (such as only year and month but no day in the month),
+ * or there may be inconsistent information (such as "Tuesday, July 15, 1996"
+ * -- July 15, 1996 is actually a Monday).
+ *
+ * 

+ * Insufficient information. The calendar will use default
+ * information to specify the missing fields. This may vary by calendar; for
+ * the Gregorian calendar, the default for a field is the same as that of the
+ * start of the epoch: i.e., UCAL_YEAR = 1970, UCAL_MONTH = JANUARY, UCAL_DATE = 1, etc.
+ *
+ * 

+ * Inconsistent information. If fields conflict, the calendar
+ * will give preference to fields set more recently. For example, when
+ * determining the day, the calendar will look for one of the following
+ * combinations of fields.  The most recent combination, as determined by the
+ * most recently set single field, will be used.
+ *
+ * \htmlonly
\endhtmlonly
+ * 
+ * \code
+ * UCAL_MONTH + UCAL_DAY_OF_MONTH
+ * UCAL_MONTH + UCAL_WEEK_OF_MONTH + UCAL_DAY_OF_WEEK
+ * UCAL_MONTH + UCAL_DAY_OF_WEEK_IN_MONTH + UCAL_DAY_OF_WEEK
+ * UCAL_DAY_OF_YEAR
+ * UCAL_DAY_OF_WEEK + UCAL_WEEK_OF_YEAR
+ * \endcode
+ * 

+ * \htmlonly
\endhtmlonly
+ *
+ * For the time of day:
+ *
+ * \htmlonly
\endhtmlonly
+ * 
+ * \code
+ * UCAL_HOUR_OF_DAY
+ * UCAL_AM_PM + UCAL_HOUR
+ * \endcode
+ * 

+ * \htmlonly
\endhtmlonly
+ *
+ * 

+ * Note: for some non-Gregorian calendars, different
+ * fields may be necessary for complete disambiguation. For example, a full
+ * specification of the historical Arabic astronomical calendar requires year,
+ * month, day-of-month and day-of-week in some cases.
+ *
+ * 

+ * Note: There are certain possible ambiguities in
+ * interpretation of certain singular times, which are resolved in the
+ * following ways:
+ * 
    
+ *     
  1.  24:00:00 "belongs" to the following day. That is,
+ *          23:59 on Dec 31, 1969 < 24:00 on Jan 1, 1970 < 24:01:00 on Jan 1, 1970
+ *
+ *     
  2.  Although historically not precise, midnight also belongs to "am",
+ *          and noon belongs to "pm", so on the same day,
+ *          12:00 am (midnight) < 12:01 am, and 12:00 pm (noon) < 12:01 pm
+ * 

+ *
+ * 

+ * The date or time format strings are not part of the definition of a
+ * calendar, as those must be modifiable or overridable by the user at
+ * runtime. Use {@link icu::DateFormat}
+ * to format dates.
+ *
+ * 

+ * Calendar provides an API for field "rolling", where fields
+ * can be incremented or decremented, but wrap around. For example, rolling the
+ * month up in the date December 12, 1996 results in
+ * January 12, 1996.
+ *
+ * 

+ * Calendar also provides a date arithmetic function for
+ * adding the specified (signed) amount of time to a particular time field.
+ * For example, subtracting 5 days from the date September 12, 1996
+ * results in September 7, 1996.
+ *
+ * 

+ * The Japanese calendar uses a combination of era name and year number.
+ * When an emperor of Japan abdicates and a new emperor ascends the throne,
+ * a new era is declared and year number is reset to 1. Even if the date of
+ * abdication is scheduled ahead of time, the new era name might not be
+ * announced until just before the date. In such case, ICU4C may include
+ * a start date of future era without actual era name, but not enabled
+ * by default. ICU4C users who want to test the behavior of the future era
+ * can enable the tentative era by:
+ * 
    
+ * 
  • Environment variable ICU_ENABLE_TENTATIVE_ERA=true.

+/**
+ * \file
+ * \brief C API: Message Catalog Wrappers
+ *
+ * This C API provides look-alike functions that deliberately resemble
+ * the POSIX catopen, catclose, and catgets functions.  The underlying
+ * implementation is in terms of ICU resource bundles, rather than
+ * POSIX message catalogs.
+ *
+ * The ICU resource bundles obey standard ICU inheritance policies.
+ * To facilitate this, sets and messages are flattened into one tier.
+ * This is done by creating resource bundle keys of the form
+ * <set_num>%<msg_num> where set_num is the set number and msg_num is
+ * the message number, formatted as decimal strings.
+ *
+ * Example:  Consider a message catalog containing two sets:
+ *
+ * Set 1: Message 4  = "Good morning."
+ *        Message 5  = "Good afternoon."
+ *        Message 7  = "Good evening."
+ *        Message 8  = "Good night."
+ * Set 4: Message 14 = "Please "
+ *        Message 19 = "Thank you."
+ *        Message 20 = "Sincerely,"
+ *
+ * The ICU resource bundle source file would, assuming it is named
+ * "greet.txt", would look like this:
+ *
+ * greet
+ * {
+ *     1%4  { "Good morning." }
+ *     1%5  { "Good afternoon." }
+ *     1%7  { "Good evening." }
+ *     1%8  { "Good night." }
+ * 
+ *     4%14 { "Please " }
+ *     4%19 { "Thank you." }
+ *     4%20 { "Sincerely," }
+ * }
+ *
+ * The catgets function is commonly used in combination with functions
+ * like printf and strftime.  ICU components like message format can
+ * be used instead, although they use a different format syntax.
+ * There is an ICU package, icuio, that provides some of
+ * the POSIX-style formatting API.

+ * \brief C API: Unicode Properties
+ *
+ * This C API provides low-level access to the Unicode Character Database.
+ * In addition to raw property values, some convenience functions calculate
+ * derived properties, for example for Java-style programming.
+ *
+ * Unicode assigns each code point (not just assigned character) values for
+ * many properties.
+ * Most of them are simple boolean flags, or constants from a small enumerated list.
+ * For some properties, values are strings or other relatively more complex types.
+ *
+ * For more information see
+ * "About the Unicode Character Database" (http://www.unicode.org/ucd/)
+ * and the ICU User Guide chapter on Properties (https://unicode-org.github.io/icu/userguide/strings/properties).
+ *
+ * Many properties are accessible via generic functions that take a UProperty selector.
+ * - u_hasBinaryProperty() returns a binary value (true/false) per property and code point.
+ * - u_getIntPropertyValue() returns an integer value per property and code point.
+ *   For each supported enumerated or catalog property, there is
+ *   an enum type for all of the property's values, and
+ *   u_getIntPropertyValue() returns the numeric values of those constants.
+ * - u_getBinaryPropertySet() returns a set for each ICU-supported binary property with
+ *   all code points for which the property is true.
+ * - u_getIntPropertyMap() returns a map for each
+ *   ICU-supported enumerated/catalog/int-valued property which
+ *   maps all Unicode code points to their values for that property.
+ *
+ * Many functions are designed to match java.lang.Character functions.
+ * See the individual function documentation,
+ * and see the JDK 1.4 java.lang.Character documentation
+ * at http://java.sun.com/j2se/1.4/docs/api/java/lang/Character.html
+ *
+ * There are also functions that provide easy migration from C/POSIX functions
+ * like isblank(). Their use is generally discouraged because the C/POSIX
+ * standards do not define their semantics beyond the ASCII range, which means
+ * that different implementations exhibit very different behavior.
+ * Instead, Unicode properties should be used directly.
+ *
+ * There are also only a few, broad C/POSIX character classes, and they tend
+ * to be used for conflicting purposes. For example, the "isalpha()" class
+ * is sometimes used to determine word boundaries, while a more sophisticated
+ * approach would at least distinguish initial letters from continuation
+ * characters (the latter including combining marks).
+ * (In ICU, BreakIterator is the most sophisticated API for word boundaries.)
+ * Another example: There is no "istitle()" class for titlecase characters.
+ *
+ * ICU 3.4 and later provides API access for all twelve C/POSIX character classes.
+ * ICU implements them according to the Standard Recommendations in
+ * Annex C: Compatibility Properties of UTS #18 Unicode Regular Expressions
+ * (http://www.unicode.org/reports/tr18/#Compatibility_Properties).
+ *
+ * API access for C/POSIX character classes is as follows:
+ * - alpha:     u_isUAlphabetic(c) or u_hasBinaryProperty(c, UCHAR_ALPHABETIC)
+ * - lower:     u_isULowercase(c) or u_hasBinaryProperty(c, UCHAR_LOWERCASE)
+ * - upper:     u_isUUppercase(c) or u_hasBinaryProperty(c, UCHAR_UPPERCASE)
+ * - punct:     u_ispunct(c)
+ * - digit:     u_isdigit(c) or u_charType(c)==U_DECIMAL_DIGIT_NUMBER
+ * - xdigit:    u_isxdigit(c) or u_hasBinaryProperty(c, UCHAR_POSIX_XDIGIT)
+ * - alnum:     u_hasBinaryProperty(c, UCHAR_POSIX_ALNUM)
+ * - space:     u_isUWhiteSpace(c) or u_hasBinaryProperty(c, UCHAR_WHITE_SPACE)
+ * - blank:     u_isblank(c) or u_hasBinaryProperty(c, UCHAR_POSIX_BLANK)
+ * - cntrl:     u_charType(c)==U_CONTROL_CHAR
+ * - graph:     u_hasBinaryProperty(c, UCHAR_POSIX_GRAPH)
+ * - print:     u_hasBinaryProperty(c, UCHAR_POSIX_PRINT)
+ *
+ * Note: Some of the u_isxyz() functions in uchar.h predate, and do not match,
+ * the Standard Recommendations in UTS #18. Instead, they match Java
+ * functions according to their API documentation.
+ *
+ * \htmlonly
+ * The C/POSIX character classes are also available in UnicodeSet patterns,
+ * using patterns like [:graph:] or \p{graph}.
+ * \endhtmlonly
+ *
+ * Note: There are several ICU whitespace functions.
+ * Comparison:
+ * - u_isUWhiteSpace=UCHAR_WHITE_SPACE: Unicode White_Space property;
+ *       most of general categories "Z" (separators) + most whitespace ISO controls
+ *       (including no-break spaces, but excluding IS1..IS4)
+ * - u_isWhitespace: Java isWhitespace; Z + whitespace ISO controls but excluding no-break spaces
+ * - u_isJavaSpaceChar: Java isSpaceChar; just Z (including no-break spaces)
+ * - u_isspace: Z + whitespace ISO controls (including no-break spaces)

+ *
+ *  In old versions of ICU, u_init() was required in multi-threaded applications
+ *  to ensure the thread safety of ICU.  u_init() is no longer needed for this purpose.
+ *
+ * @param status An ICU UErrorCode parameter. It must not be NULL.
+ *    An Error will be returned if some required part of ICU data can not

+/**
+ * Clean up the system resources, such as allocated memory or open files,
+ * used in all ICU libraries. This will free/delete all memory owned by the
+ * ICU libraries, and return them to their original load state. All open ICU
+ * items (collators, resource bundles, converters, etc.) must be closed before
+ * calling this function, otherwise ICU may not free its allocated memory
+ * (e.g. close your converters and resource bundles before calling this
+ * function). Generally, this function should be called once just before
+ * an application exits. For applications that dynamically load and unload
+ * the ICU libraries (relatively uncommon), u_cleanup() should be called
+ * just before the library unload.
+ * 

+ * u_cleanup() also clears any ICU heap functions, mutex functions or
+ * trace functions that may have been set for the process.  
+ * This has the effect of restoring ICU to its initial condition, before
+ * any of these override functions were installed.  Refer to
+ * u_setMemoryFunctions(), u_setMutexFunctions and 
+ * utrace_setFunctions().  If ICU is to be reinitialized after
+ * calling u_cleanup(), these runtime override functions will need to
+ * be set up again if they are still required.
+ * 

+ * u_cleanup() is not thread safe.  All other threads should stop using ICU
+ * before calling this function.
+ * 

+ * Any open ICU items will be left in an undefined state by u_cleanup(),
+ * and any subsequent attempt to use such an item will give unpredictable
+ * results.
+ * 

+ * After calling u_cleanup(), an application may continue to use ICU by
+ * calling u_init().  An application must invoke u_init() first from one single
+ * thread before allowing other threads call u_init().  All threads existing
+ * at the time of the first thread's call to u_init() must also call
+ * u_init() themselves before continuing with other ICU operations.  
+ * 

+ * The use of u_cleanup() just before an application terminates is optional,
+ * but it should be called only once for performance reasons. The primary
+ * benefit is to eliminate reports of memory or resource leaks originating
+ * in ICU code from the results generated by heap analysis tools.

Character Conversion C API

+ *
+ * 
This API is used to convert codepage or character encoded data to and
+ * from UTF-16. You can open a converter with {@link ucnv_open() }. With that
+ * converter, you can get its properties, set options, convert your data and
+ * close the converter.

+ *
+ * 
Since many software programs recognize different converter names for
+ * different types of converters, there are other functions in this API to
+ * iterate over the converter aliases. The functions {@link ucnv_getAvailableName() },
+ * {@link ucnv_getAlias() } and {@link ucnv_getStandardName() } are some of the
+ * more frequently used alias functions to get this information.

+ *
+ * 
When a converter encounters an illegal, irregular, invalid or unmappable character
+ * its default behavior is to use a substitution character to replace the
+ * bad byte sequence. This behavior can be changed by using {@link ucnv_setFromUCallBack() }
+ * or {@link ucnv_setToUCallBack() } on the converter. The header ucnv_err.h defines
+ * many other callback actions that can be used instead of a character substitution.

+ *
+ * 
More information about this API can be found in our
+ * User Guide.

+ * buffer of guaranteed sufficient size for a given input length and converter.
+ *
+ * Examples for special cases that are taken into account:
+ * - Supplementary code points may convert to more bytes than BMP code points.
+ *   This function returns bytes per UChar (UTF-16 code unit), not per
+ *   Unicode code point, for efficient buffer allocation.
+ * - State-shifting output (SI/SO, escapes, etc.) from stateful converters.
+ * - When m input UChars are converted to n output bytes, then the maximum m/n

+ * The number returned here does not take into account
+ * (see UCNV_GET_MAX_BYTES_FOR_STRING):
+ * - callbacks which output more than one charset character sequence per call,
+ *   like escape callbacks
+ * - initial and final non-character bytes that are output by some converters
+ *   (automatic BOMs, initial escape sequence, final SI, etc.)
+ *
+ * Examples for returned values:
+ * - SBCS charsets: 1
+ * - Shift-JIS: 2
+ * - UTF-16: 2 (2 per BMP, 4 per surrogate _pair_, BOM not counted)
+ * - UTF-8: 3 (3 per BMP, 4 per surrogate _pair_)

+ * Convert a codepage buffer into Unicode one character at a time.
+ * The input is completely consumed when the U_INDEX_OUTOFBOUNDS_ERROR is set.
+ *
+ * Advantage compared to ucnv_toUnicode() or ucnv_toUChars():
+ * - Faster for small amounts of data, for most converters, e.g.,
+ *   US-ASCII, ISO-8859-1, UTF-8/16/32, and most "normal" charsets.
+ *   (For complex converters, e.g., SCSU, UTF-7 and ISO 2022 variants,
+ *    it uses ucnv_toUnicode() internally.)
+ * - Convenient.
+ *
+ * Limitations compared to ucnv_toUnicode():
+ * - Always assumes flush=true.
+ *   This makes ucnv_getNextUChar() unsuitable for "streaming" conversion,
+ *   that is, for where the input is supplied in multiple buffers,
+ *   because ucnv_getNextUChar() will assume the end of the input at the end
+ *   of the first buffer.
+ * - Does not provide offset output.
+ *
+ * It is possible to "mix" ucnv_getNextUChar() and ucnv_toUnicode() because
+ * ucnv_getNextUChar() uses the current state of the converter
+ * (unlike ucnv_toUChars() which always resets first).
+ * However, if ucnv_getNextUChar() is called after ucnv_toUnicode()
+ * stopped in the middle of a character sequence (with flush=false),
+ * then ucnv_getNextUChar() will always use the slower ucnv_toUnicode()
+ * internally until the next character boundary.
+ * (This is new in ICU 2.6. In earlier releases, ucnv_getNextUChar() had to
+ * start at a character boundary.)
+ *
+ * Instead of using ucnv_getNextUChar(), it is recommended
+ * to convert using ucnv_toUnicode() or ucnv_toUChars()
+ * and then iterate over the text using U16_NEXT() or a UCharIterator (uiter.h)
+ * or a C++ CharacterIterator or similar.
+ * This allows streaming conversion and offset output, for example.
+ *
+ * 
Handling of surrogate pairs and supplementary-plane code points:

+ * There are two different kinds of codepages that provide mappings for surrogate characters:
+ * 
    
+ *   
  • Codepages like UTF-8, UTF-32, and GB 18030 provide direct representations for Unicode
+ *       code points U+10000-U+10ffff as well as for single surrogates U+d800-U+dfff.
+ *       Each valid sequence will result in exactly one returned code point.
+ *       If a sequence results in a single surrogate, then that will be returned
+ *       by itself, even if a neighboring sequence encodes the matching surrogate.
    • 
+ *   
  • Codepages like SCSU and LMBCS (and UTF-16) provide direct representations only for BMP code points
+ *       including surrogates. Code points in supplementary planes are represented with
+ *       two sequences, each encoding a surrogate.
+ *       For these codepages, matching pairs of surrogates will be combined into single
+ *       code points for returning from this function.
+ *       (Note that SCSU is actually a mix of these codepage types.)
    •

+ * @param converter an open UConverter

+ * @param sourceLimit points to the end of the input buffer
+ * @param err fills in error status (see ucnv_toUnicode)
+ * U_INDEX_OUTOFBOUNDS_ERROR will be set if the input
+ * is empty or does not convert to any output (e.g.: pure state-change
+ * codes SI/SO, escape sequences for ISO 2022,
+ * or if the callback did not output anything, ...).
+ * This function will not set a U_BUFFER_OVERFLOW_ERROR because
+ *  the "buffer" is the return code. However, there might be subsequent output

+/**
+ * Convert from one external charset to another using two existing UConverters.
+ * Internally, two conversions - ucnv_toUnicode() and ucnv_fromUnicode() -
+ * are used, "pivoting" through 16-bit Unicode.
+ *
+ * Important: For streaming conversion (multiple function calls for successive
+ * parts of a text stream), the caller must provide a pivot buffer explicitly,
+ * and must preserve the pivot buffer and associated pointers from one
+ * call to another. (The buffer may be moved if its contents and the relative
+ * pointer positions are preserved.)
+ *
+ * There is a similar function, ucnv_convert(),
+ * which has the following limitations:
+ * - it takes charset names, not converter objects, so that
+ *   - two converters are opened for each call
+ *   - only single-string conversion is possible, not streaming operation
+ * - it does not provide enough information to find out,
+ *   in case of failure, whether the toUnicode or
+ *   the fromUnicode conversion failed
+ *
+ * By contrast, ucnv_convertEx()
+ * - takes UConverter parameters instead of charset names
+ * - fully exposes the pivot buffer for streaming conversion and complete error handling
+ *
+ * ucnv_convertEx() also provides further convenience:
+ * - an option to reset the converters at the beginning
+ *   (if reset==true, see parameters;
+ *    also sets *pivotTarget=*pivotSource=pivotStart)
+ * - allow NUL-terminated input
+ *   (only a single NUL byte, will not work for charsets with multi-byte NULs)
+ *   (if sourceLimit==NULL, see parameters)
+ * - terminate with a NUL on output
+ *   (only a single NUL byte, not useful for charsets with multi-byte NULs),
+ *   or set U_STRING_NOT_TERMINATED_WARNING if the output exactly fills
+ *   the target buffer
+ * - the pivot buffer can be provided internally;
+ *   possible only for whole-string conversion, not streaming conversion;
+ *   in this case, the caller will not be able to get details about where an
+ *   error occurred
+ *   (if pivotStart==NULL, see below)
+ *
+ * The function returns when one of the following is true:
+ * - the entire source text has been converted successfully to the target buffer
+ * - a target buffer overflow occurred (U_BUFFER_OVERFLOW_ERROR)
+ * - a conversion error occurred
+ *   (other U_FAILURE(), see description of pErrorCode)
+ *
+ * Limitation compared to the direct use of
+ * ucnv_fromUnicode() and ucnv_toUnicode():
+ * ucnv_convertEx() does not provide offset information.
+ *
+ * Limitation compared to ucnv_fromUChars() and ucnv_toUChars():
+ * ucnv_convertEx() does not support preflighting directly.
+ *
+ * Sample code for converting a single string from
+ * one external charset to UTF-8, ignoring the location of errors:
+ *
+ * \code
+ * int32_t
+ * myToUTF8(UConverter *cnv,
+ *          const char *s, int32_t length,

+/**
+ * \file
+ * \brief C API: UConverter functions to aid the writers of callbacks
+ *
+ * 
 Callback API for UConverter 

+ * 
+ * These functions are provided here for the convenience of the callback
+ * writer. If you are just looking for callback functions to use, please
+ * see ucnv_err.h.  DO NOT call these functions directly when you are 
+ * working with converters, unless your code has been called as a callback
+ * via ucnv_setFromUCallback or ucnv_setToUCallback !!
+ * 
+ * A note about error codes and overflow.  Unlike other ICU functions,
+ * these functions do not expect the error status to be U_ZERO_ERROR.
+ * Callbacks must be much more careful about their error codes.
+ * The error codes used here are in/out parameters, which should be passed
+ * back in the callback's error parameter.
+ * 
+ * For example, if you call ucnv_cbfromUWriteBytes to write data out 
+ * to the output codepage, it may return U_BUFFER_OVERFLOW_ERROR if 
+ * the data did not fit in the target. But this isn't a failing error, 
+ * in fact, ucnv_cbfromUWriteBytes may be called AGAIN with the error
+ * status still U_BUFFER_OVERFLOW_ERROR to attempt to write further bytes,
+ * which will also go into the internal overflow buffers.
+ * 
+ * Concerning offsets, the 'offset' parameters here are relative to the start
+ * of SOURCE.  For example, Suppose the string "ABCD" was being converted 
+ * from Unicode into a codepage which doesn't have a mapping for 'B'.
+ * 'A' will be written out correctly, but
+ * The FromU Callback will be called on an unassigned character for 'B'.
+ * At this point, this is the state of the world:
+ *    Target:    A [..]     [points after A]
+ *    Source:  A B [C] D    [points to C - B has been consumed]
+ *             0 1  2  3 
+ *    codePoint = "B"       [the unassigned codepoint] 
+ * 
+ * Now, suppose a callback wants to write the substitution character '?' to
+ * the target. It calls ucnv_cbFromUWriteBytes() to write the ?. 
+ * It should pass ZERO as the offset, because the offset as far as the 
+ * callback is concerned is relative to the SOURCE pointer [which points 
+ * before 'C'.]  If the callback goes into the args and consumes 'C' also,
+ * it would call FromUWriteBytes with an offset of 1 (and advance the source
+ * pointer).

+/**
+ * \file
+ * \brief C API: UConverter predefined error callbacks
+ *
+ *  
Error Behaviour Functions

+ *  Defines some error behaviour functions called by ucnv_{from,to}Unicode
+ *  These are provided as part of ICU and many are stable, but they
+ *  can also be considered only as an example of what can be done with
+ *  callbacks.  You may of course write your own.
+ *
+ *  If you want to write your own, you may also find the functions from
+ *  ucnv_cb.h useful when writing your own callbacks.
+ *
+ *  These functions, although public, should NEVER be called directly.
+ *  They should be used as parameters to the ucnv_setFromUCallback
+ *  and ucnv_setToUCallback functions, to set the behaviour of a converter
+ *  when it encounters ILLEGAL/UNMAPPED/INVALID sequences.
+ *
+ *  usage example:  'STOP' doesn't need any context, but newContext
+ *    could be set to something other than 'NULL' if needed. The available
+ *    contexts in this header can modify the default behavior of the callback.
+ *
+ *  \code
+ *  UErrorCode err = U_ZERO_ERROR;
+ *  UConverter *myConverter = ucnv_open("ibm-949", &err);
+ *  const void *oldContext;
+ *  UConverterFromUCallback oldAction;
+ *
+ *
+ *  if (U_SUCCESS(err))
+ *  {
+ *      ucnv_setFromUCallBack(myConverter,
+ *                       UCNV_FROM_U_CALLBACK_STOP,
+ *                       NULL,
+ *                       &oldAction,
+ *                       &oldContext,
+ *                       &status);
+ *  }
+ *  \endcode
+ *
+ *  The code above tells "myConverter" to stop when it encounters an
+ *  ILLEGAL/TRUNCATED/INVALID sequences when it is used to convert from
+ *  Unicode -> Codepage. The behavior from Codepage to Unicode is not changed,
+ *  and ucnv_setToUCallBack would need to be called in order to change
+ *  that behavior too.
+ *
+ *  Here is an example with a context:
+ *
+ *  \code
+ *  UErrorCode err = U_ZERO_ERROR;
+ *  UConverter *myConverter = ucnv_open("ibm-949", &err);
+ *  const void *oldContext;
+ *  UConverterFromUCallback oldAction;
+ *
+ *
+ *  if (U_SUCCESS(err))
+ *  {
+ *      ucnv_setToUCallBack(myConverter,
+ *                       UCNV_TO_U_CALLBACK_SUBSTITUTE,
+ *                       UCNV_SUB_STOP_ON_ILLEGAL,
+ *                       &oldAction,
+ *                       &oldContext,
+ *                       &status);
+ *  }
+ *  \endcode
+ *
+ *  The code above tells "myConverter" to stop when it encounters an
+ *  ILLEGAL/TRUNCATED/INVALID sequences when it is used to convert from
+ *  Codepage -> Unicode. Any unmapped and legal characters will be
+ *  substituted to be the default substitution character.

+ * Merges two sort keys. The levels are merged with their corresponding counterparts
+ * (primaries with primaries, secondaries with secondaries etc.). Between the values
+ * from the same level a separator is inserted.
+ *
+ * This is useful, for example, for combining sort keys from first and last names
+ * to sort such pairs.
+ * See http://www.unicode.org/reports/tr10/#Merging_Sort_Keys
+ *
+ * The recommended way to achieve "merged" sorting is by
+ * concatenating strings with U+FFFE between them.
+ * The concatenation has the same sort order as the merged sort keys,
+ * but merge(getSortKey(str1), getSortKey(str2)) may differ from getSortKey(str1 + '\\uFFFE' + str2).
+ * Using strings with U+FFFE may yield shorter sort keys.
+ *
+ * For details about Sort Key Features see
+ * https://unicode-org.github.io/icu/userguide/collation/api#sort-key-features
+ *
+ * It is possible to merge multiple sort keys by consecutively merging
+ * another one with the intermediate result.
+ *
+ * The length of the merge result is the sum of the lengths of the input sort keys.
+ *
+ * Example (uncompressed):
+ * 
191B1D 01 050505 01 910505 00
+ * 1F2123 01 050505 01 910505 00

+ * will be merged as 
+ * 
191B1D 02 1F2123 01 050505 02 050505 01 910505 02 910505 00

+ *
+ * If the destination buffer is not big enough, then its contents are undefined.
+ * If any of source lengths are zero or any of the source pointers are NULL/undefined,
+ * the result is of size zero.
+ *
+ * @param src1 the first sort key
+ * @param src1Length the length of the first sort key, including the zero byte at the end;
+ *        can be -1 if the function is to find the length
+ * @param src2 the second sort key
+ * @param src2Length the length of the second sort key, including the zero byte at the end;
+ *        can be -1 if the function is to find the length
+ * @param dest the buffer where the merged sort key is written,
+ *        can be NULL if destCapacity==0
+ * @param destCapacity the number of bytes in the dest buffer
+ * @return the length of the merged sort key, src1Length+src2Length;
+ *         can be larger than destCapacity, or 0 if an error occurs (only for illegal arguments),

+ * \file
+ * \brief C API: UCollationElements
+ *
+ * The UCollationElements API is used as an iterator to walk through each 
+ * character of an international string. Use the iterator to return the
+ * ordering priority of the positioned character. The ordering priority of a 
+ * character, which we refer to as a key, defines how a character is collated 
+ * in the given collation object.
+ * For example, consider the following in Slovak and in traditional Spanish collation:
+ * 
+ * .       "ca" -> the first key is key('c') and second key is key('a').
+ * .       "cha" -> the first key is key('ch') and second key is key('a').
+ * 

+ * And in German phonebook collation,
+ * 
+ * .       "b"-> the first key is key('a'), the second key is key('e'), and
+ * .       the third key is key('b').
+ * 

+ * 
Example of the iterator usage: (without error checking)
+ * 
+ * .  void CollationElementIterator_Example()
+ * .  {
+ * .      UChar *s;
+ * .      t_int32 order, primaryOrder;
+ * .      UCollationElements *c;
+ * .      UCollatorOld *coll;
+ * .      UErrorCode success = U_ZERO_ERROR;
+ * .      str=(UChar*)malloc(sizeof(UChar) * (strlen("This is a test")+1) );
+ * .      u_uastrcpy(str, "This is a test");
+ * .      coll = ucol_open(NULL, &success);
+ * .      c = ucol_openElements(coll, str, u_strlen(str), &status);
+ * .      order = ucol_next(c, &success);
+ * .      ucol_reset(c);
+ * .      order = ucol_prev(c, &success);
+ * .      free(str);
+ * .      ucol_close(coll);
+ * .      ucol_closeElements(c);
+ * .  }
+ * 

+ * 

+ * ucol_next() returns the collation order of the next.
+ * ucol_prev() returns the collation order of the previous character.
+ * The Collation Element Iterator moves only in one direction between calls to
+ * ucol_reset. That is, ucol_next() and ucol_prev can not be inter-used. 
+ * Whenever ucol_prev is to be called after ucol_next() or vice versa, 
+ * ucol_reset has to be called first to reset the status, shifting pointers to 
+ * either the end or the start of the string. Hence at the next call of 
+ * ucol_prev or ucol_next, the first or last collation order will be returned. 
+ * If a change of direction is done without a ucol_reset, the result is 
+ * undefined.
+ * The result of a forward iterate (ucol_next) and reversed result of the  
+ * backward iterate (ucol_prev) on the same string are equivalent, if 
+ * collation orders with the value 0 are ignored.
+ * Character based on the comparison level of the collator.  A collation order 
+ * consists of primary order, secondary order and tertiary order.  The data 
+ * type of the collation order is int32_t.

+ * \brief C API: Charset Detection API
+ *
+ * This API provides a facility for detecting the
+ * charset or encoding of character data in an unknown text format.
+ * The input data can be from an array of bytes.
+ * 

+ * Character set detection is at best an imprecise operation.  The detection
+ * process will attempt to identify the charset that best matches the characteristics
+ * of the byte data, but the process is partly statistical in nature, and
+ * the results can not be guaranteed to always be correct.
+ * 

+ * For best accuracy in charset detection, the input data should be primarily
+ * in a single language, and a minimum of a few hundred bytes worth of plain text
+ * in the language are needed.  The detection process will attempt to
+ * ignore html or xml style markup that could otherwise obscure the content.
+ * 

+ * An alternative to the ICU Charset Detector is the
+ * Compact Encoding Detector, https://github.com/google/compact_enc_det.
+ * It often gives more accurate results, especially with short input samples.

+ * \brief C API: DateFormat
+ *
+ * 
 Date Format C API

+ *
+ * Date Format C API  consists of functions that convert dates and
+ * times from their internal representations to textual form and back again in a
+ * language-independent manner. Converting from the internal representation (milliseconds
+ * since midnight, January 1, 1970) to text is known as "formatting," and converting
+ * from text to millis is known as "parsing."  We currently define only one concrete
+ * structure UDateFormat, which can handle pretty much all normal
+ * date formatting and parsing actions.
+ * 

+ * Date Format helps you to format and parse dates for any locale. Your code can
+ * be completely independent of the locale conventions for months, days of the
+ * week, or even the calendar format: lunar vs. solar.
+ * 

+ * To format a date for the current Locale with default time and date style,
+ * use one of the static factory methods:
+ * 
+ * \code
+ *  UErrorCode status = U_ZERO_ERROR;
+ *  UChar *myString;
+ *  int32_t myStrlen = 0;
+ *  UDateFormat* dfmt = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, NULL, -1, NULL, -1, &status);
+ *  myStrlen = udat_format(dfmt, myDate, NULL, myStrlen, NULL, &status);
+ *  if (status==U_BUFFER_OVERFLOW_ERROR){
+ *      status=U_ZERO_ERROR;
+ *      myString=(UChar*)malloc(sizeof(UChar) * (myStrlen+1) );
+ *      udat_format(dfmt, myDate, myString, myStrlen+1, NULL, &status);
+ *  }
+ * \endcode
+ * 

+ * If you are formatting multiple numbers, it is more efficient to get the
+ * format and use it multiple times so that the system doesn't have to fetch the
+ * information about the local language and country conventions multiple times.
+ * 
+ * \code
+ *  UErrorCode status = U_ZERO_ERROR;
+ *  int32_t i, myStrlen = 0;
+ *  UChar* myString;
+ *  char buffer[1024];
+ *  UDate myDateArr[] = { 0.0, 100000000.0, 2000000000.0 }; // test values
+ *  UDateFormat* df = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, NULL, -1, NULL, 0, &status);
+ *  for (i = 0; i < 3; i++) {
+ *      myStrlen = udat_format(df, myDateArr[i], NULL, myStrlen, NULL, &status);
+ *      if(status == U_BUFFER_OVERFLOW_ERROR){
+ *          status = U_ZERO_ERROR;
+ *          myString = (UChar*)malloc(sizeof(UChar) * (myStrlen+1) );
+ *          udat_format(df, myDateArr[i], myString, myStrlen+1, NULL, &status);
+ *          printf("%s\n", u_austrcpy(buffer, myString) );
+ *          free(myString);
+ *      }
+ *  }
+ * \endcode
+ * 

+ * To get specific fields of a date, you can use UFieldPosition to
+ * get specific fields.
+ * 
+ * \code
+ *  UErrorCode status = U_ZERO_ERROR;
+ *  UFieldPosition pos;
+ *  UChar *myString;
+ *  int32_t myStrlen = 0;
+ *  char buffer[1024];
+ *
+ *  pos.field = 1;  // Same as the DateFormat::EField enum
+ *  UDateFormat* dfmt = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, -1, NULL, 0, &status);
+ *  myStrlen = udat_format(dfmt, myDate, NULL, myStrlen, &pos, &status);
+ *  if (status==U_BUFFER_OVERFLOW_ERROR){
+ *      status=U_ZERO_ERROR;
+ *      myString=(UChar*)malloc(sizeof(UChar) * (myStrlen+1) );
+ *      udat_format(dfmt, myDate, myString, myStrlen+1, &pos, &status);
+ *  }
+ *  printf("date format: %s\n", u_austrcpy(buffer, myString));
+ *  buffer[pos.endIndex] = 0;   // NULL terminate the string.
+ *  printf("UFieldPosition position equals %s\n", &buffer[pos.beginIndex]);
+ * \endcode
+ * 

+ * To format a date for a different Locale, specify it in the call to
+ * udat_open()
+ * 
+ * \code
+ *        UDateFormat* df = udat_open(UDAT_SHORT, UDAT_SHORT, "fr_FR", NULL, -1, NULL, 0, &status);
+ * \endcode
+ * 

+ * You can use a DateFormat API udat_parse() to parse.
+ * 
+ * \code
+ *  UErrorCode status = U_ZERO_ERROR;
+ *  int32_t parsepos=0;
+ *  UDate myDate = udat_parse(df, myString, u_strlen(myString), &parsepos, &status);
+ * \endcode
+ * 

+ *  You can pass in different options for the arguments for date and time style
+ *  to control the length of the result; from SHORT to MEDIUM to LONG to FULL.
+ *  The exact result depends on the locale, but generally:
+ *  see UDateFormatStyle for more details
+ * 
    
+ *   
  •    UDAT_SHORT is completely numeric, such as 12/13/52 or 3:30pm
+ *   
  •    UDAT_MEDIUM is longer, such as Jan 12, 1952
+ *   
  •    UDAT_LONG is longer, such as January 12, 1952 or 3:30:32pm
+ *   
  •    UDAT_FULL is pretty completely specified, such as
+ *          Tuesday, April 12, 1952 AD or 3:30:42pm PST.
+ * 

+ * You can also set the time zone on the format if you wish.
+ * 

+ * You can also use forms of the parse and format methods with Parse Position and
+ * UFieldPosition to allow you to
+ * 
    
+ *   
  •    Progressively parse through pieces of a string.
+ *   
  •    Align any particular field, or find out where it is for selection
+ *          on the screen.
+ * 

+ * 
Date and Time Patterns:

+ *
+ * 
Date and time formats are specified by date and time pattern strings.
+ * Within date and time pattern strings, all unquoted ASCII letters [A-Za-z] are reserved
+ * as pattern letters representing calendar fields. UDateFormat supports
+ * the date and time formatting algorithm and pattern letters defined by
+ * UTS#35
+ * Unicode Locale Data Markup Language (LDML) and further documented for ICU in the
+ * ICU
+ * User Guide.

+ * UDataInfo contains the properties about the requested data.
+ * This is meta data.
+ *
+ * 
This structure may grow in the future, indicated by the
+ * size field.

+ *
+ * 
ICU data must be at least 8-aligned, and should be 16-aligned.
+ * The UDataInfo struct begins 4 bytes after the start of the data item,
+ * so it is 4-aligned.
+ *
+ * 
The platform data property fields help determine if a data
+ * file can be efficiently used on a given machine.
+ * The particular fields are of importance only if the data
+ * is affected by the properties - if there is integer data
+ * with word sizes > 1 byte, char* text, or UChar* text.

+ *
+ * 
The implementation for the udata_open[Choice]()
+ * functions may reject data based on the value in isBigEndian.
+ * No other field is used by the udata API implementation.

+ *
+ * 
The dataFormat may be used to identify
+ * the kind of data, e.g. a converter table.

+ *
+ * 
The formatVersion field should be used to
+ * make sure that the format can be interpreted.
+ * It may be a good idea to check only for the one or two highest
+ * of the version elements to allow the data memory to
+ * get more or somewhat rearranged contents, for as long
+ * as the using code can still interpret the older contents.

+ *
+ * 
The dataVersion field is intended to be a
+ * common place to store the source version of the data;
+ * for data from the Unicode character database, this could
+ * reflect the Unicode version.

+ * \file
+ * \brief C API: Format a date interval.
+ *
+ * A UDateIntervalFormat is used to format the range between two UDate values
+ * in a locale-sensitive way, using a skeleton that specifies the precision and
+ * completeness of the information to show. If the range smaller than the resolution
+ * specified by the skeleton, a single date format will be produced. If the range
+ * is larger than the format specified by the skeleton, a locale-specific fallback
+ * will be used to format the items missing from the skeleton.
+ *
+ * For example, if the range is 2010-03-04 07:56 - 2010-03-04 19:56 (12 hours)
+ * - The skeleton jm will produce
+ *   for en_US, "7:56 AM - 7:56 PM"
+ *   for en_GB, "7:56 - 19:56"
+ * - The skeleton MMMd will produce
+ *   for en_US, "Mar 4"
+ *   for en_GB, "4 Mar"
+ * If the range is 2010-03-04 07:56 - 2010-03-08 16:11 (4 days, 8 hours, 15 minutes)
+ * - The skeleton jm will produce
+ *   for en_US, "3/4/2010 7:56 AM - 3/8/2010 4:11 PM"
+ *   for en_GB, "4/3/2010 7:56 - 8/3/2010 16:11"
+ * - The skeleton MMMd will produce
+ *   for en_US, "Mar 4-8"
+ *   for en_GB, "4-8 Mar"
+ * 
+ * Note:  the "-" characters in the above sample output will actually be
+ * Unicode 2013, EN_DASH, in all but the last example.
+ *
+ * Note, in ICU 4.4 the standard skeletons for which date interval format data
+ * is usually available are as follows; best results will be obtained by using
+ * skeletons from this set, or those formed by combining these standard skeletons
+ * (note that for these skeletons, the length of digit field such as d, y, or
+ * M vs MM is irrelevant (but for non-digit fields such as MMM vs MMMM it is
+ * relevant). Note that a skeleton involving h or H generally explicitly requests
+ * that time style (12- or 24-hour time respectively). For a skeleton that
+ * requests the locale's default time style (h or H), use 'j' instead of h or H.
+ *   h, H, hm, Hm,
+ *   hv, Hv, hmv, Hmv,
+ *   d,
+ *   M, MMM, MMMM,
+ *   Md, MMMd,
+ *   MEd, MMMEd,
+ *   y,
+ *   yM, yMMM, yMMMM,
+ *   yMd, yMMMd,
+ *   yMEd, yMMMEd
+ *
+ * Locales for which ICU 4.4 seems to have a reasonable amount of this data
+ * include:
+ *   af, am, ar, be, bg, bn, ca, cs, da, de (_AT), el, en (_AU,_CA,_GB,_IE,_IN...),
+ *   eo, es (_AR,_CL,_CO,...,_US) et, fa, fi, fo, fr (_BE,_CH,_CA), fur, gsw, he,
+ *   hr, hu, hy, is, it (_CH), ja, kk, km, ko, lt, lv, mk, ml, mt, nb, nl )_BE),

+
+/**
+ * IDNA2003: This function implements the ToASCII operation as defined in the IDNA RFC.
+ * This operation is done on single labels before sending it to something that expects
+ * ASCII names. A label is an individual part of a domain name. Labels are usually
+ * separated by dots; e.g. "www.example.com" is composed of 3 labels "www","example", and "com".
+ *
+ * IDNA2003 API Overview:
+ *
+ * The uidna_ API implements the IDNA protocol as defined in the IDNA RFC
+ * (http://www.ietf.org/rfc/rfc3490.txt).
+ * The RFC defines 2 operations: ToASCII and ToUnicode. Domain name labels
+ * containing non-ASCII code points are processed by the
+ * ToASCII operation before passing it to resolver libraries. Domain names
+ * that are obtained from resolver libraries are processed by the
+ * ToUnicode operation before displaying the domain name to the user.
+ * IDNA requires that implementations process input strings with Nameprep
+ * (http://www.ietf.org/rfc/rfc3491.txt),
+ * which is a profile of Stringprep (http://www.ietf.org/rfc/rfc3454.txt),
+ * and then with Punycode (http://www.ietf.org/rfc/rfc3492.txt).
+ * Implementations of IDNA MUST fully implement Nameprep and Punycode;
+ * neither Nameprep nor Punycode are optional.
+ * The input and output of ToASCII and ToUnicode operations are Unicode
+ * and are designed to be chainable, i.e., applying ToASCII or ToUnicode operations
+ * multiple times to an input string will yield the same result as applying the operation
+ * once.
+ * ToUnicode(ToUnicode(ToUnicode...(ToUnicode(string)))) == ToUnicode(string) 
+ * ToASCII(ToASCII(ToASCII...(ToASCII(string))) == ToASCII(string).
+ *
+ * @param src               Input UChar array containing label in Unicode.
+ * @param srcLength         Number of UChars in src, or -1 if NUL-terminated.
+ * @param dest              Output UChar array with ASCII (ACE encoded) label.
+ * @param destCapacity      Size of dest.
+ * @param options           A bit set of options:

+ *                              and do not use STD3 ASCII rules
+ *                              If unassigned code points are found the operation fails with 
+ *                              U_UNASSIGNED_ERROR error code.
+ *
+ *  - UIDNA_ALLOW_UNASSIGNED    Unassigned values can be converted to ASCII for query operations

+ *                              are treated as normal Unicode code points.
+ *
+ *  - UIDNA_USE_STD3_RULES      Use STD3 ASCII rules for host name syntax restrictions
+ *                              If this option is set and the input does not satisfy STD3 rules,  
+ *                              the operation will fail with U_IDNA_STD3_ASCII_RULES_ERROR

+ * \file
+ * \brief C API: Locale ID functionality similar to C++ class Locale
+ *
+ * 
 ULoc C API for Locale 

+ * A Locale represents a specific geographical, political,
+ * or cultural region. An operation that requires a Locale to perform
+ * its task is called locale-sensitive and uses the Locale
+ * to tailor information for the user. For example, displaying a number
+ * is a locale-sensitive operation--the number should be formatted
+ * according to the customs/conventions of the user's native country,
+ * region, or culture.  In the C APIs, a locales is simply a const char string.
+ *
+ * 

+ * You create a Locale with one of the three options listed below.
+ * Each of the component is separated by '_' in the locale string.
+ * \htmlonly
\endhtmlonly
+ * 
+ * \code
+ *       newLanguage
+ * 
+ *       newLanguage + newCountry
+ * 
+ *       newLanguage + newCountry + newVariant
+ * \endcode
+ * 

+ * \htmlonly
\endhtmlonly
+ * The first option is a valid ISO
+ * Language Code. These codes are the lower-case two-letter
+ * codes as defined by ISO-639.
+ * You can find a full list of these codes at a number of sites, such as:
+ * 

+ * http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt
+ *
+ * 

+ * The second option includes an additional ISO Country
+ * Code. These codes are the upper-case two-letter codes
+ * as defined by ISO-3166.
+ * You can find a full list of these codes at a number of sites, such as:
+ * 

+ * http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html
+ *
+ * 

+ * The third option requires another additional information--the 
+ * Variant.
+ * The Variant codes are vendor and browser-specific.
+ * For example, use WIN for Windows, MAC for Macintosh, and POSIX for POSIX.
+ * Where there are two variants, separate them with an underscore, and
+ * put the most important one first. For
+ * example, a Traditional Spanish collation might be referenced, with
+ * "ES", "ES", "Traditional_WIN".
+ *
+ * 

+ * Because a Locale is just an identifier for a region,
+ * no validity check is performed when you specify a Locale.
+ * If you want to see whether particular resources are available for the
+ * Locale you asked for, you must query those resources. For
+ * example, ask the UNumberFormat for the locales it supports
+ * using its getAvailable method.
+ * 
Note: When you ask for a resource for a particular
+ * locale, you get back the best available match, not necessarily
+ * precisely what you asked for. For more information, look at
+ * UResourceBundle.
+ *
+ * 

+ * The Locale provides a number of convenient constants
+ * that you can use to specify the commonly used
+ * locales. For example, the following refers to a locale
+ * for the United States:
+ * \htmlonly
\endhtmlonly
+ * 
+ * \code
+ *       ULOC_US
+ * \endcode
+ * 

+ * \htmlonly
\endhtmlonly
+ *
+ * 

+ * Once you've specified a locale you can query it for information about
+ * itself. Use uloc_getCountry to get the ISO Country Code and
+ * uloc_getLanguage to get the ISO Language Code. You can
+ * use uloc_getDisplayCountry to get the
+ * name of the country suitable for displaying to the user. Similarly,
+ * you can use uloc_getDisplayLanguage to get the name of
+ * the language suitable for displaying to the user. Interestingly,
+ * the uloc_getDisplayXXX methods are themselves locale-sensitive
+ * and have two versions: one that uses the default locale and one
+ * that takes a locale as an argument and displays the name or country in
+ * a language appropriate to that locale.
+ *
+ * 

+ * The ICU provides a number of services that perform locale-sensitive
+ * operations. For example, the unum_xxx functions format
+ * numbers, currency, or percentages in a locale-sensitive manner. 
+ * 

+ * \htmlonly
\endhtmlonly
+ * 
+ * \code
+ *     UErrorCode success = U_ZERO_ERROR;
+ *     UNumberFormat *nf;
+ *     const char* myLocale = "fr_FR";
+ * 
+ *     nf = unum_open( UNUM_DEFAULT, NULL, success );          
+ *     unum_close(nf);
+ *     nf = unum_open( UNUM_CURRENCY, NULL, success );
+ *     unum_close(nf);
+ *     nf = unum_open( UNUM_PERCENT, NULL, success );   
+ *     unum_close(nf);
+ * \endcode
+ * 

+ * \htmlonly
\endhtmlonly
+ * Each of these methods has two variants; one with an explicit locale
+ * and one without; the latter using the default locale.
+ * \htmlonly
\endhtmlonly
+ * 
+ * \code 
+ * 
+ *     nf = unum_open( UNUM_DEFAULT, myLocale, success );          
+ *     unum_close(nf);
+ *     nf = unum_open( UNUM_CURRENCY, myLocale, success );
+ *     unum_close(nf);
+ *     nf = unum_open( UNUM_PERCENT, myLocale, success );   
+ *     unum_close(nf);
+ * \endcode
+ * 

+ * \htmlonly
\endhtmlonly
+ * A Locale is the mechanism for identifying the kind of services
+ * (UNumberFormat) that you would like to get. The locale is
+ * just a mechanism for identifying these services.
+ *
+ * 

+ * Each international service that performs locale-sensitive operations 
+ * allows you
+ * to get all the available objects of that type. You can sift
+ * through these objects by language, country, or variant,
+ * and use the display names to present a menu to the user.
+ * For example, you can create a menu of all the collation objects
+ * suitable for a given language. Such classes implement these
+ * three class methods:
+ * \htmlonly
\endhtmlonly
+ * 
+ * \code
+ *       const char* uloc_getAvailable(int32_t index);
+ *       int32_t uloc_countAvailable();
+ *       int32_t
+ *       uloc_getDisplayName(const char* localeID,
+ *                 const char* inLocaleID, 
+ *                 UChar* result,
+ *                 int32_t maxResultSize,
+ *                  UErrorCode* err);
+ * 
+ * \endcode
+ * 

+ * \htmlonly
\endhtmlonly
+ * 

+ * Concerning POSIX/RFC1766 Locale IDs, 
+ *  the getLanguage/getCountry/getVariant/getName functions do understand
+ * the POSIX type form of  language_COUNTRY.ENCODING\@VARIANT
+ * and if there is not an ICU-stype variant, uloc_getVariant() for example
+ * will return the one listed after the \@at sign. As well, the hyphen
+ * "-" is recognized as a country/variant separator similarly to RFC1766.
+ * So for example, "en-us" will be interpreted as en_US.  
+ * As a result, uloc_getName() is far from a no-op, and will have the
+ * effect of converting POSIX/RFC1766 IDs into ICU form, although it does
+ * NOT map any of the actual codes (i.e. russian->ru) in any way.
+ * Applications should call uloc_getName() at the point where a locale ID
+ * is coming from an external source (user entry, OS, web browser)
+ * and pass the resulting string to other ICU functions.  For example,
+ * don't use de-de\@EURO as an argument to resourcebundle.

+ * \file
+ * \brief C API: MessageFormat
+ *
+ * 
MessageFormat C API 

+ *
+ * 
MessageFormat prepares strings for display to users,
+ * with optional arguments (variables/placeholders).
+ * The arguments can occur in any order, which is necessary for translation
+ * into languages with different grammars.
+ *
+ * 
The opaque UMessageFormat type is a thin C wrapper around
+ * a C++ MessageFormat. It is constructed from a pattern string
+ * with arguments in {curly braces} which will be replaced by formatted values.
+ *
+ * 
Currently, the C API supports only numbered arguments.
+ *
+ * 
For details about the pattern syntax and behavior,
+ * especially about the ASCII apostrophe vs. the
+ * real apostrophe (single quote) character \htmlonly’\endhtmlonly (U+2019),
+ * see the C++ MessageFormat class documentation.
+ *
+ * 
Here are some examples of C API usage:
+ * Example 1:
+ * 
+ * \code
+ *     UChar *result, *tzID, *str;
+ *     UChar pattern[100];
+ *     int32_t resultLengthOut, resultlength;
+ *     UCalendar *cal;
+ *     UDate d1;
+ *     UDateFormat *def1;
+ *     UErrorCode status = U_ZERO_ERROR;
+ *
+ *     str=(UChar*)malloc(sizeof(UChar) * (strlen("disturbance in force") +1));
+ *     u_uastrcpy(str, "disturbance in force");
+ *     tzID=(UChar*)malloc(sizeof(UChar) * 4);
+ *     u_uastrcpy(tzID, "PST");
+ *     cal=ucal_open(tzID, u_strlen(tzID), "en_US", UCAL_TRADITIONAL, &status);
+ *     ucal_setDateTime(cal, 1999, UCAL_MARCH, 18, 0, 0, 0, &status);
+ *     d1=ucal_getMillis(cal, &status);
+ *     u_uastrcpy(pattern, "On {0, date, long}, there was a {1} on planet {2,number,integer}");
+ *     resultlength=0;
+ *     resultLengthOut=u_formatMessage( "en_US", pattern, u_strlen(pattern), NULL, resultlength, &status, d1, str, 7);
+ *     if(status==U_BUFFER_OVERFLOW_ERROR){
+ *         status=U_ZERO_ERROR;
+ *         resultlength=resultLengthOut+1;
+ *         result=(UChar*)realloc(result, sizeof(UChar) * resultlength);
+ *         u_formatMessage( "en_US", pattern, u_strlen(pattern), result, resultlength, &status, d1, str, 7);
+ *     }
+ *     printf("%s\n", austrdup(result) );//austrdup( a function used to convert UChar* to char*)
+ *     //output>: "On March 18, 1999, there was a disturbance in force on planet 7
+ * \endcode
+ * 

+ * Typically, the message format will come from resources, and the
+ * arguments will be dynamically set at runtime.
+ * 

+ * Example 2:
+ * 
+ * \code
+ *     UChar* str;
+ *     UErrorCode status = U_ZERO_ERROR;
+ *     UChar *result;
+ *     UChar pattern[100];
+ *     int32_t resultlength, resultLengthOut, i;
+ *     double testArgs= { 100.0, 1.0, 0.0};
+ *
+ *     str=(UChar*)malloc(sizeof(UChar) * 10);
+ *     u_uastrcpy(str, "MyDisk");
+ *     u_uastrcpy(pattern, "The disk {1} contains {0,choice,0#no files|1#one file|1<{0,number,integer} files}");
+ *     for(i=0; i<3; i++){
+ *       resultlength=0; 
+ *       resultLengthOut=u_formatMessage( "en_US", pattern, u_strlen(pattern), NULL, resultlength, &status, testArgs[i], str); 
+ *       if(status==U_BUFFER_OVERFLOW_ERROR){
+ *         status=U_ZERO_ERROR;
+ *         resultlength=resultLengthOut+1;
+ *         result=(UChar*)malloc(sizeof(UChar) * resultlength);
+ *         u_formatMessage( "en_US", pattern, u_strlen(pattern), result, resultlength, &status, testArgs[i], str);
+ *       }
+ *       printf("%s\n", austrdup(result) );  //austrdup( a function used to convert UChar* to char*)
+ *       free(result);
+ *     }
+ *     // output, with different testArgs:
+ *     // output: The disk "MyDisk" contains 100 files.
+ *     // output: The disk "MyDisk" contains one file.
+ *     // output: The disk "MyDisk" contains no files.
+ * \endcode
+ *  

+ *
+ *
+ * Example 3:
+ * 
+ * \code
+ * UChar* str;
+ * UChar* str1;
+ * UErrorCode status = U_ZERO_ERROR;
+ * UChar *result;
+ * UChar pattern[100];
+ * UChar expected[100];
+ * int32_t resultlength,resultLengthOut;
+
+ * str=(UChar*)malloc(sizeof(UChar) * 25);
+ * u_uastrcpy(str, "Kirti");

+ * u_uastrcpy(str1, "female");

+/**
+ * A mutable set of Unicode characters and multicharacter strings.  Objects of this class
+ * represent character classes used in regular expressions.
+ * A character specifies a subset of Unicode code points.  Legal
+ * code points are U+0000 to U+10FFFF, inclusive.
+ *
+ * 
The UnicodeSet class is not designed to be subclassed.
+ *
+ * 
UnicodeSet supports two APIs. The first is the
+ * operand API that allows the caller to modify the value of
+ * a UnicodeSet object. It conforms to Java 2's
+ * java.util.Set interface, although
+ * UnicodeSet does not actually implement that
+ * interface. All methods of Set are supported, with the
+ * modification that they take a character range or single character
+ * instead of an Object, and they take a
+ * UnicodeSet instead of a Collection.  The
+ * operand API may be thought of in terms of boolean logic: a boolean
+ * OR is implemented by add, a boolean AND is implemented
+ * by retain, a boolean XOR is implemented by
+ * complement taking an argument, and a boolean NOT is
+ * implemented by complement with no argument.  In terms
+ * of traditional set theory function names, add is a
+ * union, retain is an intersection, remove
+ * is an asymmetric difference, and complement with no
+ * argument is a set complement with respect to the superset range
+ * MIN_VALUE-MAX_VALUE
+ *
+ * 
The second API is the
+ * applyPattern()/toPattern() API from the
+ * java.text.Format-derived classes.  Unlike the
+ * methods that add characters, add categories, and control the logic
+ * of the set, the method applyPattern() sets all
+ * attributes of a UnicodeSet at once, based on a
+ * string pattern.
+ *
+ * 
Pattern syntax

+ *
+ * Patterns are accepted by the constructors and the
+ * applyPattern() methods and returned by the
+ * toPattern() method.  These patterns follow a syntax
+ * similar to that employed by version 8 regular expression character
+ * classes.  Here are some simple examples:
+ *
+ * \htmlonly
\endhtmlonly
+ *   
+ *     
+ *       
+ *       
+ *     
+ *       
+ *       
+ *     
+ *       
+ *       
+ *     
+ *     
+ *       
+ *       
+ *     
+ *     
+ *       
+ *       
+ *     
+ *     
+ *       
+ *       
+ *     
+ *     
+ *       
+ *       
+ *     
+ *   
[]No characters
[a]The character 'a'
[ae]The characters 'a' and 'e'
[a-e]The characters 'a' through 'e' inclusive, in Unicode code
+ *       point order
[\\u4E01]The character U+4E01
[a{ab}{ac}]The character 'a' and the multicharacter strings "ab" and
+ *       "ac"
[\\p{Lu}]All characters in the general category Uppercase Letter

+ * \htmlonly
\endhtmlonly
+ *
+ * Any character may be preceded by a backslash in order to remove any special
+ * meaning.  White space characters, as defined by UCharacter.isWhitespace(), are
+ * ignored, unless they are escaped.
+ *
+ * 
Property patterns specify a set of characters having a certain
+ * property as defined by the Unicode standard.  Both the POSIX-like
+ * "[:Lu:]" and the Perl-like syntax "\\p{Lu}" are recognized.  For a
+ * complete list of supported property patterns, see the User's Guide
+ * for UnicodeSet at
+ * 
+ * https://unicode-org.github.io/icu/userguide/strings/unicodeset.
+ * Actual determination of property data is defined by the underlying
+ * Unicode database as implemented by UCharacter.
+ *
+ * 
Patterns specify individual characters, ranges of characters, and
+ * Unicode property sets.  When elements are concatenated, they
+ * specify their union.  To complement a set, place a '^' immediately
+ * after the opening '['.  Property patterns are inverted by modifying
+ * their delimiters; "[:^foo]" and "\\P{foo}".  In any other location,
+ * '^' has no special meaning.
+ *
+ * 
Since ICU 70, "[^...]", "[:^foo]", "\\P{foo}", and "[:binaryProperty=No:]"
+ * perform a “code point complement” (all code points minus the original set),
+ * removing all multicharacter strings,
+ * equivalent to .complement().removeAllStrings().
+ * The complement() API function continues to perform a
+ * symmetric difference with all code points and thus retains all multicharacter strings.
+ *
+ * 
Ranges are indicated by placing two a '-' between two
+ * characters, as in "a-z".  This specifies the range of all
+ * characters from the left to the right, in Unicode order.  If the
+ * left character is greater than or equal to the
+ * right character it is a syntax error.  If a '-' occurs as the first
+ * character after the opening '[' or '[^', or if it occurs as the
+ * last character before the closing ']', then it is taken as a
+ * literal.  Thus "[a\-b]", "[-ab]", and "[ab-]" all indicate the same
+ * set of three characters, 'a', 'b', and '-'.
+ *
+ * 
Sets may be intersected using the '&' operator or the asymmetric
+ * set difference may be taken using the '-' operator, for example,
+ * "[[:L:]&[\\u0000-\\u0FFF]]" indicates the set of all Unicode letters
+ * with values less than 4096.  Operators ('&' and '|') have equal
+ * precedence and bind left-to-right.  Thus
+ * "[[:L:]-[a-z]-[\\u0100-\\u01FF]]" is equivalent to
+ * "[[[:L:]-[a-z]]-[\\u0100-\\u01FF]]".  This only really matters for
+ * difference; intersection is commutative.
+ *
+ * 
+ * 
[a]The set containing 'a'
+ * 
[a-z]The set containing 'a'
+ * through 'z' and all letters in between, in Unicode order
+ * 
[^a-z]The set containing
+ * all characters but 'a' through 'z',
+ * that is, U+0000 through 'a'-1 and 'z'+1 through U+10FFFF
+ * 
[[pat1][pat2]]
+ * The union of sets specified by pat1 and pat2
+ * 
[[pat1]&[pat2]]
+ * The intersection of sets specified by pat1 and pat2
+ * 
[[pat1]-[pat2]]
+ * The asymmetric difference of sets specified by pat1 and
+ * pat2
+ * 
[:Lu:] or \\p{Lu}
+ * The set of characters having the specified
+ * Unicode property; in
+ * this case, Unicode uppercase letters
+ * 
[:^Lu:] or \\P{Lu}
+ * The set of characters not having the given
+ * Unicode property
+ *

Note:

+ *   there are usually very few opportunities for failure other than a shortage
+ *   of memory, error codes in low-level C++ string methods would be inconvenient,
+ *   and the error code as the last parameter (ICU convention) would prevent
+ *   the use of default parameter values.
+ *   Instead, such methods set the UnicodeSet into a "bogus" state
+ *   (see isBogus()) if an error occurs.
