I don't understand---are you saying this is supposed to work? Is the
well, i wrote: it looks like some pos feaure is not applied ...
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
no, but turning them on makes tracing cumbersome
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:
What am I missing?
As Khaled mentioned ... are these proper otf fonts or do they rely on
specific features in the microsoft engine?
Most opentype features are quite generic and should work ok but if
something special is needed more info is needed.
