I agree, there should be two formats. Though by
tweaking the cache index we could easily introduce the
ability to load multiple fonts.

Agree, no sense in re-inventing the wheel!

Think we should include revisions, e.g. GB2312-80, in

It's probably useful to include it as a flag. The
implementation can decide what to do if the bytes are
appropriate for the platform.
