Pascal,

Thanks for the suggestion.  Below is the mode line for the response
that I'm writing; it indicates ascii.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-=--:@**--F3  mutt-sunny-1000-6359-23   87% (422,0)    (Text Server Fill)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

(Mutt, my MUA, runs emacsclient as an editor.)

C-h v buffer-file-coding-system tells me

   | buffer-file-coding-system is a variable defined in `C source code'.
   | Its value is undecided-unix
   | Local in buffer mutt-sunny-1000-6359-19; global value is utf-8-unix

I've tried 

   M-x set-buffer-file-coding-system RET utf-8-unix RET

This changes the beginning of the mode line to "-=-U:", but it does
not change the <Compose> key behavior that I described earlier.

iso-transl addresses half of the problem.  C-x 8 " u inserts the
correct character.  Within emacsclient, the character appears as a "?"
(char 63) but the actual character is "ü" (char 252).
