how to teach emacs that ' + c = ç

[Filipe Silva <filipe.silva@gmail.com>]

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 compose the ç char with ' + c = ç when
using international us-keyboard layouts.

I don't know why, but by default linux distros come configured so that when
you type this combination ' + c= ć, which is an invalid char in Brazilian
portuguese, and so I'm screwed.

So I did this:

   -

   Editing the 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

   changing 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"
   -

   replaced "ć" to "ç" and "Ć" to "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
   -

      add two lines on /etc/environment

      GTK_IM_MODULE=cedilla QT_IM_MODULE=cedilla
      -

      restart my computer.

And all is working fine in firefox, chromium, scite, gvim or any other gui
tool, but no emacs. on emacs, ' + cinsist on producing ć, despite my
efforts.


So I ask you, how can I teach emacs to produce ç and not ć in this scenario?


thanks in advance.
