Character based Search and Replace font size

[anacond11]

Hi, I have a file with paragraphs like this:

设宴[設-] shèyàn* {E} v.o. give a dinner/banquet | Tā ∼ zhāodài le wǒ. 他∼招待了我。 He gave me a dinner party.



The Asian font is "KaiTi", the Latin font is "Century Schoolbook". I tried to do a Format Search and Replace to make the Asian font a little bigger, but Search and Replace would change the font size of the entire paragraph. The KaiTi part should be 13 points, the Century Schoolbook part 11 points.

I tried to define a character-based style sheet, but any changes still affect both the Asian and the Latin part. Is there a way to replace either only the Latin or the Asian part? The text is pasted in from another application. Thanks!
