[ö] or [?ö]?  I forgot to mention that I tried to use [?ö] before I
posted my article.  [?ö] (or [ö]) neither works under X *nor* on the
console.

    state 0x0, keycode 47 (keysym 0xf6, odiaeresis), same_screen YES,
    XLookupString gives 1 bytes:  "ö"

I'm pretty sure that [?\366] worked in earlier versions of Emacs.  I
think that I started to use the above piece of code when Emacs 19 was
current.

The locale is set to de_DE.iso88591 which, according to "locale -a" is
supported by the C library. I also tried to use de_DE.

My .emacs is encoded in ASCII.  I encoded it in Latin-1 when I
experimented with [?ö].  I also tried UTF-8.

I just realized that (local-set-key [?ö] "{") works under X if the
expression is executed from within the buffer that contains the C
file.  If the expression is evaluated in the c-mode-common-hook it
doesn't work.  On the other hand, it is no problem to bind { to keys
like f1, return or a, for example.
