I agree with this.

The GTK+ solution is simple: everything is (assumed) UTF-8 and if you
really need, you can override it with the environment variables.

This sound like a good solution to me, but I must admit zero experience in
that area, since I hate non-ASCII filenames, so I always transliterate the
filenames to ASCII. Of course my language uses an alphabet which is a
superset of Latin alphabet, and for other alphabets it is not that simple.
