Vincent,

does FOray font expose this type of information Jeremias described 
below?


Not yet. I'll expose the problem on FOray-dev.
If you choose to implement this functionality now I suggest you to make things 
very simple, as Jeremias said. This wouldn't be completely useless anyway: this 
would help me to adapt FOrayFont thereafter, as I'll easily find where to work 
in the code!

AFAICS, no, it doesn't do that, yet.

It's probably easiest for now to do as Batik does. However, Type 1 fonts
provide information about sub and super scripts (size and placement) in
the PFM file. That data is currently not parsed. I assume there's
something similar in TrueType. So ideally, the font would supply the
information how exactly to handle super/sub script. But keeping it
simple for now will certainly not hurt.
