Are you sure it is a good idea to use Çç?  It will cause Emacs to
consider, e.g., абвгҪҫÇçҪҫабвг, as 3 words, not one word, for the
purposes of cursor motion commands, like M-f and C-<LEFT>.  That's
because Emacs always stops these movement commands when text switches
to a different script, and here we will have a switch from Cyrillic to
Latin and back.

So maybe we should use Ҫҫ after all?
