You're right, Jason! Arabic is different from being just another =20 proportional script. Many characters are not typed by the same glyphs =20= in every possible place of a word. Many characters change their shape =20= when used as the first (initial) character, its last (final) =20 character, or somewhere in-between. So up to three glyphs represent =20 one character. Text processors using TT or OT font tables are able to =20= select the proper glyph (shape) of the character. It's something like =20= building ligatures in Latin based scripts. (Besides this Arabic bears more computer problems with "accents" above =20= and below and writing it, for special, festive, purposes, almost =20 diagonally...) -- Greetings Pete I love deadlines.
