It is now more or less clear to me that in order to  get a "full" 
list of glyphs, I need to merge the new STIX submission tables 
(that is created from the new stix-tbl.submit) with the stuff that 
is already available in Unicode (which follows from the reference 
tables), and possibly add things from Mathfont (this is the latex 
project Matthias and Ulrik are working on).

OK.

I'll take your word for it, I'm not going to check for myself.

OK, I'm trying to get new gifs now for the empty ones (running wget 
on chars.unicode.org).

So I need to re-create the tables from your file(s), and everything 
should be OK again, yes?

I can figure this out myself without too many difficulties, the main 
problem was in getting the gif files for the glyphs. This is now 
working thanks to Ulrik.

To me, this is a minor point. If I want to play safe (and I 
definately want that), I will have to create or find fonts for 
everything that is existing in the tables now, since obviously 
somebody needs the glyph. Whether or not the glyph actually makes 
it into Unicode is a minor issue.
