I was talking about other operating systems (which might need their own 
implementation of boost::filesystem), not about Win32 or the current 
implementation.

If an operating system accepts multibyte character file and directory names 
(as I think some of the Asian operating systems do), then a 
boost::filesystem implementation is obliged to also accept multibyte 
character file and directory names.
