Re: [RFC PATCH] Windows: Assume all file names to be UTF-8 encoded.

IMHO, you grossly underestimate what is needed to enable UTF-8 encoding
in Windows. AFAIK, Microsoft C runtime library does not support UTF-8,
so you have to wrap all C functions taking 'char*' as an input parameter.
For example, think about what is going to happen if Git tries to print
a simple error message:
  fprintf (stderr, "unable to open %s", path);

Since there is no real file system abstraction beyond using stdio_
(AFAIK), I need to hack it by replacing fopen (and open). Probably_
opendir/readdir as well (might be trickier), and possibly even hack_
around main() to parse the wchar_t command-line instead of the char copy.

And the command-line is not the only source of file names. Some Git
commands read list of files from stdin usually though the pipe. In
what encoding are they going to be?
