No, I don't think it is.  No version of 'ls' I know of, including GNU
'ls', recodes file names, they just emit the bytestream they find in
the directory.  The idea is that you create files and display them
under the same setting of the locale's codeset.  If you change the
codeset between the time you created the file and the time you display
it, you are toast.  AFAIK, this happens on any Posix filesystem.
