Bugs with German umlauts in file name

[David Reitter]

I can confirm general display problems with umlauts in file names (see  
also screenshot) in current 22 builds (Carbon).
Incidentally: does Emacs still crash when started from a path name  
that contains anything but 7-bit ASCII characters?

Emacs also brings up an annoying question about encoding when  
automatically saving 'places' at the end of the session.
