Comment (by boost.flamefire@…):

 Came across the same problem. I was wondering: If boost has to fall back
 to narrow character set on mingw then why doesn't it convert the filename
 correctly?

 In my case I have to write to the user directory but the username contains
 an umlaut. Internally I use all UTF8 in the string (std::string) and also
 have the path as an UTF8 string. When I pass it to e.g. memory mapped
 files or the directory functions it works. In MSVC it also works (widechar
 open function for fstream) but on MinGW it falls back to narrow char open
 and (maybe?) passes the utf8 string raw into the open function instead of
 converting it to the system encoding.
