I will take that script (and use the output of the ttx fonttool as well)
to estimate the glyph ids for each latex symbol. This will take
a week or so. If it is not possible to reach the charmap values
by get_charmap for the belleek fonts one could use an additional
dict with the charmaps values.

Maybe because this fonts use charmaps values beyond 0x20:
 <cmap_format_4 platformID="3" platEncID="0" version="0">
   <map code="0x1" name="Delta"/><!-- &lt;control> -->
   <map code="0x2" name="Theta"/><!-- &lt;control> -->
   <map code="0x3" name="Lambda"/><!-- &lt;control> -->

A cmap value for 0x0 is missing:
   <map code="0x0" name=".null"/>     (um fonts)

But this is just a wild guess.

Carl
