AFIAK, there's no neat way to do it.  Converting the wstring back to ANSI/multi-byte is A) a pain and B) wrong in the
long run, since the Unicode name might have characters not representable in an MBCS.  IMO the standard library stream
classes should offer wchar_t constructors independent of whether the stream's CharT is char or wchar_t.
