ISCII 1991 is the character set standard, and I don't recall it containing any
rendering sections.
But to make my point, if you support Devanagari, are you using the XDVNG
fonts, the LeapLite TrueType font, Frans Velthuis' MF fonts, or the one that
comes with Avinash Chopde's ITRANS? Those are the four Devangari fonts I can
think of immediately, and all of them have a different set of glyphs arranged
in different orders. The Unicode Devanagari font I put together from the
XDVNG fonts has approximately 200 glyphs to support Hindi and Marathi along
with a few common ligatures and alternate glyph shapes.
The point I am trying to mak is that a renderer has to be written for each
font because none of them share the same sets of glyphs.
Thanks for the pointer to the rxvt stuff though. It could be handy.
