Message 224086 - Python tracker

I have deleted all my old files and added only my current implementation of the stream objects as the only relevant part to this issue.

@Mark Summerfield: I have added __init__.py to the new version of win_unicode_console. If there is any problem, you can start an issue on project GitHub site or contact me.

@Victor Stinner, @Nick Coghlan: What's wrong with looking on Windows wide strings as on UTF-16-LE encoded bytes and building the raw stream objects around this?
