You might be interested in the upcoming LWG Issue #454:

basic_filebuf::open should accept wchar_t names [27.8.1.3]
Bill Plauger
30 Jan 2004

    basic_filebuf *basic_filebuf::open(const char *, ios_base::open_mode);

should be supplemented with the overload:

    basic_filebuf *basic_filebuf::open(const wchar_t *,
ios_base::open_mode);

Depending on the operating system, one of these forms is fundamental and
the other requires an implementation-defined mapping to determine the
actual filename.
