                The fonts in question are TrueType fonts and in general an Asian font is made up of several glyphs. I think that we aren't correctly scaling some of those pieces. I'll would have to do a little more debuging but I'm pretty sure this is the issue. We can fix it but it's going to take some effort.

                Some sort of scalling issue with the composite glyph. Pretty sure this is the same as PDF-415
