very difficult to do in Italian

I'm not sure you could spell it in Italian, because the only way to spell our "ch" sound is to follow a c with either an e or an i. And then there's the words-almost-always-end-in-a-vowel-sound rule. So the letter following the "c" which makes it say "ch" must be pronounced, as well. So you'd get something like "auci" ("Ouch-ee").
