Curious. I have

setxkbmap us_intl

in my init scripts and have the opposite problem (not actually a problem
for me since in my languages ç is not used).

' + c produces ç in Emacs but ć elsewhere.

BUT...

if I start Emacs with -Q, then ' + c indeed produces as the other
applications ć.

After looking at my customizations, tried

LANG=C emacs -Q

and now ' + c gives ç.

Hope this gives you some clues.
