Cannot remap umlaut keys

Cannot remap umlaut keys

[Andreas Voegele]

I used to remap the umlaut keys in CC Mode but the following key
bindings no longer work when Emacs 21.3.1 is run under X.  The
bindings work if Emacs is started on the Linux console though.

(add-hook 'c-mode-common-hook
 '(lambda ()
    (local-set-key [?\366] "{")    ; ö -> {
    (local-set-key [?\344] "}")    ; ä -> }
    (local-set-key [?\326] "[")    ; Ö -> [
    (local-set-key [?\304] "]")    ; Ä -> ]
    (local-set-key [?\337] "\\"))) ; ß -> \

Is there another way to remap the umlaut keys that works under X and
on the Linux console?

?\366 is not the same as ö.  How about

   (local-set-key [ö] "{")

This might not always work, tho.  If it doesn't, then maybe your
locale is not set properly.  The problem is that the .emacs file
should be in the same coding-system as your keyboard (and the
keyboard's coding system under X is determined by your locale).

[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.

Oops, it should have been [?ö] indeed.

No doubt about that.  But I fixed this Emacs-19 bug ;-)

Hmm... it should have worked.

Have you tried putting a -*- coding: latin-1 -*- on the first line
to make sure that it is read with the proper coding system ?

The problem is that there are many different ö characters in Emacs
and it's important that Emacs read it as (make-char 'latin-iso8859-1 118)
(i.e. 2294) since it is the event generated by Emacs for the odiaeresis
key in an iso-8859-1 locale.

I should have thought of setting the coding explicitly.  I use -*-
coding: utf-8 -*- in a lot of other files.

There's still the problem that I have to use (local-set-key [246] "(")
on the Linux text console in addition to (local-set-key [?ö] "("),
which only works under X.  But I can live with this minor problem.

The -*- coding -*- thingy should not be necessary.  It seems to work OK for
me with Emacs-CVS and LANG=fr_CH.iso-8859-1, but if you could check it
yourself it would be helpful.

(local-set-key [?ö] "(") should work in the console as well, although it
might require a (set-keyboard-coding-system 'latin-1) or something
like that (in Emacs-CVS, the keyboard coding-system should be set
automatically based on the locale).

I've just built Emacs-CVS and I can confirm that the coding is
recognized properly.  The keyboard coding-system is also set
automatically.

I think I'll stick to the CVS version.  The list of changes is quite
impressive.

Thanks a lot for your help.

Thank you for testing it.

In Emacs 21.3, with LC_CTYPE=en_US.ISO_8859-1, I tested this:

,----[ ~/.emacs (complete, nothing else) ]
| (global-set-key [2276] 'test2276) ; ä
| (global-set-key [ö]    'testoe) ; ö
| (global-set-key [252]  'test252) ; ü
`----

Result:

ä -> Symbol's function definition is void: test2276
ö -> ö (i.e. self-insert-command)
ü -> ü (i.e. self-insert-command)

Bye, Reiner.

Thanks, that works.  Does this mean that I have to maintain different
bindings for unibyte and multibyte mode?

I don't know.  I don't even understand _why_ this alternative works
opposed to the others. :-/ I'm sure Stefan can explain.  The thread
around <news:5lr8kyfhi4.fsf@rum.cs.yale.edu> [1] may also be
interesting.  BTW: It seems that Stefan's explanations don't exactly
apply to Emacs 21.3 (and 21.2).

Why do you want to use unibyte mode in the first place?
