I was missing the obvious; you forgot to imbue a locale. Your test 
program works fine once that is done. See below. Because I didn't know 
your preferred encoding, I used the UTF-8 codecvt facet Boost.Filesystem 
uses for testing.

Maybe it would be better if Boost.Filesystem defaulted to some likely 
encoding, such as UTF-8.

            std::locale global_loc = std::locale();
            fs::detail::utf8_codecvt_facet utf8_facet;
            std::locale loc( global_loc, &utf8_facet );
            fs::wpath_traits::imbue( loc );
