I've set up my keyboard layout in arch with

localectl set-x11-keymap us pc104 intl

By default, in this layout, the ' is a dead character. It is called a dead acute. In Portuguese, we are used to composing the ç char using ' + c = ç when using international US-keyboard layouts.

I don't know why, but by default GNU/Linux distros come configured so that when you type this combination ' + c you get ć, which is an invalid char in Brazilian Portuguese.

So I did this. I've edited the following files: sudo vim /usr/lib/gtk-3.0/3.0.0/immodules.cache sudo vim /usr/lib/gtk-2.0/2.10.0/immodules.cache

I change the line:

"cedilla" "Cedilla" "gtk20" "/usr/share/locale" "az:ca:co:fr:gv:oc:pt:sq:tr:wa"

to

"cedilla" "Cedilla" "gtk20" "/usr/share/locale" "az:ca:co:fr:gv:oc:pt:sq:tr:wa:en"

I also replaced "ć" with "ç" and "Ć" with "Ç" on /usr/share/X11/locale/en_US.UTF-8/Compose:

$ sudo cp /usr/share/X11/locale/en_US.UTF-8/Compose /usr/share/X11/locale/en_US.UTF-8/Compose.bak 

$ sed 's/ć/ç/g' < /usr/share/X11/locale/en_US.UTF-8/Compose | sed 's/Ć/Ç/g' > Compose 
$ sudo mv Compose /usr/share/X11/locale/en_US.UTF-8/Compose

I also added two lines on /etc/environment:

GTK_IM_MODULE=cedilla 
QT_IM_MODULE=cedilla

and then I restarted my computer.

And then it worked. It works fine in firefox, chromium, scite, gvim or any other gui tool. But not in Emacs. In Emacs, ' + c insists on producing ć, despite my efforts.

How can I teach Emacs to produce ç and not ć when I type a dead acute ' + c?

  • Which Emacs input method are you using?

  • The note on the the useXIM X resource in C-h i g (emacs)Table of Resources might be relevant?

  • ‘useXIM’ (class ‘UseXIM’) Disable use of X input methods (XIM) if ‘false’ or ‘off’. This is only relevant if your Emacs is built with XIM support. It might be useful to turn off XIM on slow X client/server links.

It looks like the portuguese-prefix input method may be what you're looking for?

e.g. C-uC-\ portuguese-prefix RET (and then C-\ to toggle thereafter).

'c then produces ç

Use C-hC-\ to see the details for an input method.

To configure this as your default input method (i.e. the one that you get by typing just C-\), you would add the following to your init file:

(setq default-input-method "portuguese-prefix")

  • C-h i g (emacs)Select Input Method may also be useful to you.

  • the portuguese prefix did not work. but c-u c-x = with point above ç tells me that C-x 8 RET e7 RET produces ç. It also tells me this:

    A breakthrough: if I launch emacs with this line: LANG=C emacs then it works. see here: lists.gnu.org/archive/html/help-gnu-emacs/2017-07/msg00070.html

I got ' c to produce ç with this in my .emacs:

(global-set-key (kbd "<dead-acute> c") (lambda () (interactive) (insert-string "ç")))

    insert-string was declared obsolete in Emacs-22 and I think it was removed in Emacs-26. Just use insert.

Just put LANG=C before calling your emacs boostrap command.

LANG=C emacs

and it works like a charm.
