It sounds like a poorly created or corrupted font.
Is there a reason you picked an oriental font for English text?
Hi Steve and Peter,
I'm afraid I didn't know it's an oriental font. I guess I just liked the look of it.
If STHeiti is just going to cause problems, I'll ditch it, though.
Thanks for the advice,
If you still want to use this font you can uncheck Use Typographer's Quotes on Indesign>Preferences>Type and the extra spaces go away.
Wow... that works beautifully.
I've done it, but before proceeding too much further I'll google and try to find out more about this "Use Typographer's Quotes" setting. Don't want it to bite me down the road.
Thanks very much for the tip—
