man locale

The encoding is whatever the file was created with. There is no way
to tell. The best you can do is hope that it matches LC_CTYPE. If
you are ambitious, check for common patterns of the most likely
encodings. Of course, on short strings like filenames this is likely
to give many false matches.

The easy way out is to require utf8, and let the user blame himself if
he chooses to use something else.
