US International keyboard for portuguese language writers

[Julio Maranhao]

Hi! I speak portuguese (I'm brazillian) and use Breezy
(breezy,breezy-updates,breezy-security).

So I use KDE 3.4.3 with last dist-upgrade.
My language locale is "US English" and the country locale is set to
"Brazil".
Using KDE GUI "Keyboard Layout" configurator, I selected:
setxkbmap -model pc105 -layout us -variant intl

This is almost correct. The "cedilha" symbol is mapped to AltGr^{comma} ==
"ç" instead of the common sequence {deadkey apostrophe}+c which is actually
showing "ć".

Any hints on this? It doesn't seem to be Kubuntu specific. Probably KDE or
Xorg specific. I just want to change the file configuration to ajust this
and the deadkeys behavior. Just to learn.

Cheers
