The way it works with other portable libs such as glib is that all filenames
are given in UTF-8 (char *), then converted inside the lib to wchar_t
* or whatever
is needed (native UTF-8 on POSIX systems e.g.). (iconv() does the trick
for you in any case).

However it will be a roundtrip in Windows since there will be many
wchar_t -> UTF-8 -> wchar_t conversions for no use, so perhaps this
proposal is better anyway.
