Amiri has a zero-width kashida glyph (that gets mapped to from camp, Then replace it by actual Kashida using GSUB), a hack I implemented to prevent Kashida justification in LibreOffice (why I also made LibreOffice check that font has a Kashida glyph with +ve width b before it tries to do kashida justification). I can imagine IE doing a similar check. You can try with Aref Ruqaa font which does a similar hack. _______________________________________________ HarfBuzz mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/harfbuzz
