dead_acute + c produces ç

[Frederik Elwert]

I am using the default German keyboard layout in a de_DE.UTF8 environment. When typing the key sequence ´ + c (<dead_acute> <c>), I am getting ç (ccedilla), but I would expect ć (cacute).

The cause seems to be in /usr/share/X11/locale/iso8859-15/Compose, which has these lines:

# Useful for portuguese language
<dead_acute> <C> : "\307" Ccedilla
<dead_acute> <c> : "\347" ccedilla

I don’t know why we should have a special case for this: We can have ccedilla already with <dead_cedilla> <c>, and currently there is no way to get cacute. It is really counterintuitive to use the acute on a c and get a c with cedilla.

Um, seems I was wrong. According to compose.dir, en_US.UTF-8/Compose is responsible for the de_DE.UTF-8 locale. In that file, cacute seems to be defined correctly, at least I cannot find the issue. Fixing the iso8859-15 compose file does not fix the issue in an UTF-8 environment.

So where is the faulty definition? Don’t manage to track it down …

For Ubuntu 12.04 x86_64, the following worked:
1. Check en_US.UTF-8/Compose
2. Add export GTK_IM_MODULE="xim" to /etc/environment for a global change or create a ~/.gnomerc with that line for a single user's change
3. restart X
