Description
This is an experimental partial replacement for X-Symbol.
Ultimately it should be possible to extend it to handle control characters for subscript/superscript and other highlights.
What is missing at the moment is a coding system. The (efficient) way to do this requires writing decode/encode functions in the dedicated CCL language, maybe. Another possibility might be to use a decode map in quail, but examples/documentation are thin on the ground.

This work is now largely complete in the PG 4.0 branch. This version uses GNU Emacs composition properties to change the view on the buffer without altering the underlying text --- far more robust. The composition properties are managed using font-lock.
Instead of a coding system, the buffer format mechanism (format.el) seems more appropriate, and much easier to configure. This has been added to the 3.7 code now. Font-locking for sub/supers shouldn't be too hard to add for the 3.7 patch release.
