This doesn't work well, because you cannot easily take apart and
construct file names in encoding-agnostic ways. For example, some
multibyte sequence in an arbitrary encoding could include the '/' or
'\' characters, so searching for directory separators could fail,
unless you use multibyte-aware string functions (which is a nuisance,
because these functions only support a single locale at a time).
So I think using UTF-8 internally is a much better way.
