Cedilla on Fedora 18 and GTK 3.X

I couldn't find anywhere a recipe for putting cedilla as default on Fedora 18. None of them work properly for my environment, which is:

• Desktop in a non-Portuguese language (in my case English)
• Make the combination + produce a cedilla (ç)

The way I did it is:

1. Set Input Method to NONE:

Go to

-> System -> Preferences ->  Input Method Selector.

This should produce a window similar to that below. Select: No Input Method

2. Set, in your .bash_profile, to use ibus:

Edit your ${HOME}/.bash_profile file and add the following:

export GTK_IM_MODULE=ibus

Or:

#---
cat >> ${HOME}/.bash_profile << __END__
export GTK_IM_MODULE=ibus
__END__
#---

3. Setup GTK:

Add your language (in red) to the corresponding lines in:

/usr/lib/gtk-3.0/3.0.0/immodules.cache: 
"/usr/lib/gtk-3.0/3.0.0/immodules/im-cedilla.so"
"cedilla" "Cedilla" "gtk30" "/usr/share/locale" "az:ca:co:fr:gv:oc:pt:sq:tr:wa:de:en"

/usr/lib64/gtk-3.0/3.0.0/immodules.cache:
"/usr/lib64/gtk-3.0/3.0.0/immodules/im-cedilla.so"
"cedilla" "Cedilla" "gtk30" "/usr/share/locale" "az:ca:co:fr:gv:oc:pt:sq:tr:wa:en:de"

/etc/gtk-2.0/x86_64-redhat-linux-gnu/gtk.immodules:
"/usr/lib64/gtk-2.0/2.10.0/immodules/im-cedilla.so"
"cedilla" "Cedilla" "gtk20" "/usr/share/locale" "az:ca:co:fr:gv:oc:pt:sq:tr:wa:en:de"
