Though arabic has got presentation form in Unicode, inputting these characters will make it like CJK script. So for ease of use, we must use the Open Type or AAT fonts. Better if font developer use proper unicode values in fonts for these intial/mid/final shapes. And even arabic script sometimes required different shapes of init/mid/final depending upon previous characters. And if someone started thinking for Nastaliq script, he need lots of glyphs(6 times more than indic scripts) - Pravin S > > -- > Shriramana Sharma > > _______________________________________________ > HarfBuzz mailing list > [email protected] > http://lists.freedesktop.org/mailman/listinfo/harfbuzz >
