Hi Behdad, I have added few test cases for Lohit Devanagari, tried to cover single combination for each Devanagari feature will provide patch for other Lohit fonts soon. Pango output 0xffffff whenever there is ZWNJ/ZWJ bug there is no such glyph index present in font, dunno what to write in test case for that. I have ignored it for now. Thanks, Pravin Satpute
