Yep, there is another way. First convert the UTF-8 string to a UTF-16
string using software of your choice. Then construct a
boost::filesystem::path with the UTF-16 string as an argument.
Alternately, assign the UTF-16 string to a boost::filesystem::path.

Say the resulting path is named p. Then p.string() will return a
std::string containing the path in native format, native codepage.

Does that solve your problem?
