There are two approaches:

* If you always want all class path arguments and returned values with
a value type of char to be treated as being UTF-8 encoded, and aren't
worried about changing a potentially dangerous global, then do this:

    #include <boost/filesystem/detail/utf8_codecvt_facet.hpp>
    std::locale global_loc = std::locale();
    std::locale loc(global_loc, new

* If you only want one specific path to treat its narrow character
arguments and returns as UTF-8, do this:

    boost::filesystem::detail::utf8_codecvt_facet utf8;
    boost::filesystem::path p;
    p.assign(u8"...", utf8); // many other path functions can take a
codecvt argument, too

By the way, you can use a UTF-8 codecvt facet from someone else if you prefer.
