Dear gang,
I have redone this. Now there are two filter sequences, one for main text
and one for using the arabic-font digits in math mode.
http://wiki.contextgarden.net/Aleph_Guide#Installing
has been updated, get the new uni2cuni.zip. I'll update m-gamma soon so
this will be part of the distro if Hans accepts-)
Here is a test file that works here. Note (see the sqrt example) that
omarb apparently does not have U+066B, the Arabic decimal point. And the
Arabic comma maps to the lm comma in math mode (since omarb maps the
arabic comma to U+002C in the omarb virtual
font-sigh). So there is further work needed to get this all just right,
including recompiling the fonts etc...
Best
Idris
