I need to get more familiar with X internals.

I'd think anything applicable would have been discussed on this list
or the xfree86 one.

I don't think that would be needed. The clients would just send 4-byte codes
for each character, and it's up to the client programmer or Xserver user to
use an appropriately licenced font for whatever language they want.

Lazy toolkit writers have been going to client-side fonts just to avoid
16-bit X protocol problems instead of fixing it. This is a problem for
anonymous X client servers where the user does not have an account on
the client server for making their own fonts available.

Clients using font-metric information need to be able to get all the
metrics for a whole character set from the X server. The client machine
could have some default fonts for large character sets that would otherwise
need a large download.
