Hi y'all!
I am a newbie, so first off I want to apologize if I'm posting about a topic already solved.

I wonder if it's possible to change font properties just for a set of "characters", specifically, I'm interested in changing the font properties just of chinese characters leaving untouched the latin-alphabet lettes.

I would also like to set the substitution, let's say, only for words starting with the letter X or ending in the letter Y etc.

Hope to hear some news.
Thanks in advance.
