I'm writing a Python app that connects to a remote host and receives back byte data, which I unpack using Python's built-in struct module. My problem is with the strings, as they include mu... | 0 | python,string,unicode,encoding | 2008-10-13T14:26:00.000 | 0 | 197,759 | I would write a codec that incrementally scanned the string and decoded the bytes as they came along. Essentially, you would have to separate strings into chunks with a consistent encoding and decode those and append them to the strings that followed them. | 0 | 3,280 | false | 0 | 1 | Dealing with a string containing multiple character encodings | 197,786 |

EDIT: Not true at all.
Here's the problem -- poor testing on my part -- omnicomplete WAS working for parts of my project, just not most of it.
