[Python-Dev] Removal of Win32 ANSI API

It should fail sometimes, right? Not for windows-1252, but certainly
for shift-jis (you know better than me). It seems that whether
MultiByteToWideChar will fail depends on whether MB_ERR_INVALID_CHARS
is given or not. I don't know what it will do if this flag is not
given - my guess it fills in REPLACEMENT CHARACTER.

This I don't understand. os.stat doesn't return text at all -
so what do you want to convert?

Well, readlink is new on Windows, and symlinks are not widespread.
So there is no backwards compatibility concern here.
