I don't understand---are you saying this is supposed to work? Is the
trick supposed to be using fnt-20 or in being careful not to turn on
unused features? (To be on the safe side, since I was switching
between them in testing, I was turning on all the features Microsoft
calls Indic.) I tried your example and, yes, one shaping looks
correct, but there was no reordering and now some of the characters
print out on top of each other (which is incorrect). I tried the same
routine, using fnt-20 and commenting out unused features, for some
other fonts:
Akaash:

Bangla, from the University of Chicago:
http://salrc.uchicago.edu/resources/fonts/available/bengali/
and Arial Unicode MS (standard on Windows),
and I got no improvement in their rendering in Context. They work
fine in Notepad, Firefox, and TexnicCenter though, for example.
What am I missing?
