wpath.external_file_string() returns the type and encoding required by the
platform. For Mac OS X, the type is std::string, and the Apple web site says
the encoding is Unicode. I assume that means UTF-8, although I couldn't find
that stated explicitly.

Sure. That's why external_file_string is exposed.

Internationalization should be a bit easier with Boost.Filesystem Version 3
that I'm working on, because there is a single path type.
