ISO-8859-1 encoded file names and UTF-8

[Karl Eichwalder]

UTF-8 Emacs sometimes fails to manage ISO-8859-1 file names.  I do not
know how you can rename or convert these file name from ISO-8859-1 to
UTF-8 encoded names using Emacs.

I created some ISO-8859-1 encoded file names (on top of the ext2 file
system).  Start a UTF-8 Emacs:

    LANG=de_DE.UTF-8 emacs

Call dired on the directory containing these files; you will see
something like (attention, Emacs/Gnus will normalize the names when I
send the mail!):

Note, the buffer is marked "-u" in the modeline.

Now go to a file name with umlauts and press 'f' to visit the file:

Debugger entered--Lisp error: (error "File no longer exists; type `g' to update 
Dired buffer")
  signal(error ("File no longer exists; type `g' to update Dired buffer"))
  error("File no longer exists; type `g' to update Dired buffer")
  dired-get-file-for-visit()
  dired-find-file()
  call-interactively(dired-find-file)

If you will need more info, please ask.  I can also send a tar archive
containing those stupid file names.
