I/O on windows with utf-8 enabled has issues

[msteveb]

As explained here, http://utf8everywhere.org, accessing files on Windows with non-ansi filenames requires use "wide" APIs. This means using _wfopen rather than fopen, CreateFileW instead of CreateFile, etc.

Here is a list of known APIs that need to be addressed:

• fopen (_wfopen)
• stat (_wstat64)
• rename (_wrename)
• mkdir (_wmkdir)
• opendir/readdir (_wopendir, _wreaddir)
• _open (_wopen)
• access (_waccess)
