Re: Cedilla input in UTF-8 locale with dead keys.

[Jan Djärv]

FWIW, Gtk+ has a special handling of this.  Gtk+ also processes all compose 
itself, rather than using X.  See Gtk+ sources, modules/input/imcedilla.c:

/* The difference between this and the default input method is the handling
 * of C+acute - this method produces C WITH CEDILLA rather than C WITH ACUTE.
 * For languages that use CCedilla and not acute, this is the preferred mapping,
 * and is particularly important for pt_BR, where the us-intl keyboard is
 * used extensively.
 */

Since Emacs does not use Gtk+ for character input, we don't get that mapping.
