I can try to implement that after.
Ideally, I think hamza and madda should come first, then shadda, then the vowel marks then everything else: * hamzat and maddat: U+0653-U+0655, U+065F, U+0674, U+06E4 * shadda: U+0651 * vowel marks: U+064B-U+0650, U+0652, U+0656-U+065E, U+08F0-U+08F2 Regards, Khaled _______________________________________________ HarfBuzz mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/harfbuzz
