Yes, I already saw you working on stuff like that the last days; thanks
a lot!

I think there is still a subtle bug left; in a ISO-8859-1 locale do:

touch "Maler Müller"

Then call emacs:

LANG=de_DE.UTF-8 emacs -q --no-site --no-splash .

In dired you can see:

  -rw-r--r--  1 ke  users   0 2003-03-19 16:10 Maler M\374ller\374rle
                                     good part ^^^^^^^^^^^^^^^|||||||
                              trailing garbage ------------>>>^^^^^^^

There is trailing garbage (otherwise the escape sequence is okay for
me!).

The function works for me.

If the user calls rename-file it should be up to him to specify a proper
file name.  In other words I vote to provide a separate function like
convert-file-name to do the right thing; by default convert-file-name
should try to convert the file name to the user's locale.

Hope this helps.
