Yes, I'm using the default settings of Mac OS X 10.5.

I just found out that I get the ü correctly displayed when
invoking Aquamacs like this: emacs -nw -Q

How can I find that out?

chris:~ mnissl$ locale
LANG="de_DE.UTF-8"
LC_COLLATE="de_DE.UTF-8"
LC_CTYPE="de_DE.UTF-8"
LC_MESSAGES="de_DE.UTF-8"
LC_MONETARY="de_DE.UTF-8"
LC_NUMERIC="de_DE.UTF-8"
LC_TIME="de_DE.UTF-8"
LC_ALL=

Geeze. And I thought Emacs 22.x would have sorta reached a
feature complete state of "basic" editing.

I'm not fond of switching to a specific codepage if I have a 
unicode capable operating system and editor -- at least I thought 
I had ones ...

Then why does the Emacs file prompt feature the same bug as
Terminal (this happens both with Aquamacs 1.3 and the Emacs
bundled with Mac OS X 10.5):

1. C-x C-f rü<tab>    (nothing happens)
2. Backspace (to delete the ü), u<tab>     (autocompletes)
3. Delete backwards until you only have the r
4. Hit tab ... and you'll end up with r̈ckerstattung.txt

Try the same in Terminal with "ls rü<tab>" ...

Err, Mac OS file open dialogs do not feature a prompt to type the 
file name ... only mouse clicks!

Well, in fact I switched to Mac OS X in order *not* to have the 
conversation we have now ... :-(

Thanks for your input,
