This problem is caused by the gfx PS generator which does not handle TTC face index correctly.I've made a patch to fix this problem.

vlad, do you think you can review this?  I'm really not very familiar with XFT stuff...

If you're not comfortable with this, do you know who might be?

The patch looks good.  It does exactly what cairo and Xft do.

Sounds like an r+ to me.  ;)  I'll go out on a limb here and sr.

I checked in the fix on trunk.  Should we try to fix this on the 1.8 branch as well?  How serious a problem is it in daily use?

As far as I know, there's no free TTC (true type collection) font available for Linux, which is why I haven't stumbled upon the problem. Some Linux users just copy TTCs from their Windows and there might be some commercial TTC fonts used by Linux users (or other Unix users).

Anyway, the patch is simple and safe enough so that I'd fix it in the 1.8 branch.

Should be pretty safe and helps with some non-Western fonts, apparently...
