(*
В библиотеке введён дополнительный тип: UniString.
На старых компиляторах
UniString = WideString
На новых
UniString = UnicodeString (и == string, если включено UNICODE)
Все функции существуют в следующих версиях:
Function: агностическая функция (для типа string)
AnsiFunction (FunctionA): версия для AnsiString
WideFunction (FunctionW): версия для WideString
UniFunction (FunctionU): версия для UniString (оптимальная)
Библиотека старается наверстать все упущения Delphi, и добавляет недостающие
функции:
Агностические, если в Дельфи они забыты (объявлены, как AnsiFunction).
Подлинные Ansi, если в Дельфи под этим именем агностическая.
Подлинные Wide, если таких нет в стандартных библиотеках.
И оптимальные Uni.
В виде исключения, если подлинных Wide в дельфи нет, они иногда объявляются
здесь сразу для UnicodeString.
Таким образом, UniFunction/WideFunction даёт вам поддержку юникода в наилучшем
возможном виде, а простая Function работает со строками, которые приняты
по умолчанию на платформе компиляции.
Следует помнить, что WideChar == UnicodeChar, и PWideChar в любом случае
ничуть не отличается от PUnicodeChar. Поэтому функции, которые работают
с PWideChar, не требуют изменений.
Используются проверки:
IFDEF UNICODE: для проверки типа string (Ansi или Unicode)
IF CompilerVersion>=21: для проверки доступности новых типов и функций
Например:
IFDEF UNICODE => string == UnicodeString (по умолчанию включен юникод)
IF CompilerVersion>=21 => UniString == UnicodeString (юникод ДОСТУПЕН В ПРИНЦИПЕ)
*)
(*
О скорости разных методов работы со строками.
I. Приведение к PWideChar
==============================
@s[1] вызывает UniqueStringU
PWideChar(s) вызывает WCharFromUStr
Поэтому если нужно просто получить указатель, делайте:
PWideChar(pointer(s))+offset*SizeOf(WideChar)
Это самый быстрый способ (в несколько раз быстрее, никаких вызовов).
II. Length
=============
Зачем-то вызывает UniqueStringU.
Если нужно просто проверить на непустоту, используйте:
pointer(s) <> nil
*)
const
BOM_UTF16BE: AnsiString = #254#255; //FE FF
BOM_UTF16LE: AnsiString = #255#254; //FF FE
//должны быть ansi, иначе получится два юникод-символа
type

В юникод-версиях Дельфи некоторые Ansi-функции объявлены как UniString.
Например,
UpperCase - принимает string и работает только с ASCII
AnsiUpperCase - принимает string и работает со всеми строками
То есть, Ansi фактически Uni.
Само по себе это не страшно (главное помнить не использовать UpperCase),
но при компиляции Ansi-кода возникают дурацкие варнинги.

// 350. 两个数组的交集 II
//
// 给定两个数组，编写一个函数来计算它们的交集。
//
// 示例 1:
//
// 输入: nums1 = [1,2,2,1], nums2 = [2,2]
// 输出: [2,2]
// 示例 2:
//
// 输入: nums1 = [4,9,5], nums2 = [9,4,9,8,4]
// 输出: [4,9]
// 说明：
//
// 输出结果中每个元素出现的次数，应与元素在两个数组中出现的次数一致。
// 我们可以不考虑输出结果的顺序。
// 进阶:
//
// 如果给定的数组已经排好序呢？你将如何优化你的算法？
// 如果 nums1 的大小比 nums2 小很多，哪种方法更优？
// 如果 nums2 的元素存储在磁盘上，磁盘内存是有限的，并且你不能一次加载所有的元素到
// 内存中，你该怎么办？
//
// class Solution {
// public int[] intersect(int[] nums1, int[] nums2) {

Example showing usage of GLBlur
Adding it to the scene root will blur all the scene.
Adding a GLBlur to an object will make it blur only that object
(note that you might need to sort objects to avoid z-order issues
or you can set GLScene1.ObjectSorting = osRenderFarthestFirst)
You can choose a GLBlur effect from the "presets" property or
set the parameters yourself (see GLBlur.pas)

Just don't preteend you wrote it, and leave this comment in the text, and
I'll be happy. Consider it my resume :)

Quick RTTI gives you simple string based access to RTTI data in any
RTTI capable component. WIth the addition of my lowx and strutils you
can also read and write basic XML structures based off of your component.
SUPER easy.
Just set RTTIObject:= some TPersistent descendant (any TComponent) and you will have
nice string based access to all its fields by name... cool huh.
I am testing an "Object Shell" that will allow using QuickRTTI and
Toadbase to use/store RTTI Objects thru memory mapped files, ie..
web based persistence.. I know, why not use CORBA..
hell, in the
words of Disney via Mr W.T.Pooh "...I wouldn't climb this tree / if a bear
flew like a bee / but I wouldn't be a bear then / so I guess I wouldn't
care then..."
Perhaps having the simple ability to convert TComponents to and from XML
will open up a new world for delphi... now to work on RPC !..
