A couple of additional thoughts:

• The most complete cjk font projects require 2 fonts to handle all cjk
characters
• There are language specific glyph variations between chinese and
japanese, so ideal situation is to use diffetent fonts tailored for each

We're hoping to find some way to take a number of open source fonts and
combine them into one large pan-unicode font.
