At the moment, I'm having to deal with this when writing my dissertation:
Whenever a line contains Chinese characters, the line spacing gets messed up; making them smaller doesn't help and just makes them unreadable, and changing the line spacing between individual lines doesn't make it look any better. I have the same problem whether the line spacing is 1.0, 1.15 or 1.5 (it's currently 1.5)
Can anyone suggest a way to fix it? I don't want to submit this with such ugly paragraphs.
