If you have your locale set then it is usually expected that your
pathnames are in your locale's encoding just like stdio, text files,
etc.

While it is possible to mix filenames in various encodings on some
filesystems it is usually not desirable (as is the case with text
files - they are easiest to view when in your locale's encoding).
Other filesystems require a single encoding and the filenames are
probably converted from the current locale to the on-disk encoding in
libc and filenames invalid in the current locale's encoding cannot be
created/accessed. This is the case at least for hfsplus on OSX  and
perhaps some networked filesystems.
