It sounds a bit tricky with the eTeX line, because of the 256-character- per-TeX-font limit. Not necessarily impossible, but certainly contortionate. I'm led to think about XeTeX--a fair number of people on the list are happy with the AAT/OpenType support they get with some very sophisticated Arabic fonts. And when you consider the educational price of a Mac mini, you're still way below the price of some software packages... :) > Do you think TeXFont can be tweaked to generate ovf's and ofm's as >well=3F =46rom my experience, it's certainly possible. For it to be done, it needs a confluence of time, motivation, and expertise! -- =3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D= -=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D Adam T.
