Known Issues

  • Medial and Final high hamza characters may have collisions as these likely do not occur.
  • Lam/high hamza alef ligature does not form as it likely does not occur.
  • Many OpenType applications do not yet support Unicode 13.0 and may not correctly handle the characters in range U+08BE..U+08C7.
  • There is an OpenType bug with diacritic position (in the context of a shadda) on lam-alef.
  • There is an OpenType bug in context of kashida insertion (affects diacritics and spacing).
  • There is a Graphite bug related to spacing of U+2E41.
  • Delta is encoded as U+2209 rather than U+2206.
  • There is a TypeTuner bug related to the shadda+kasra feature.
  • The honorific ligatures that are currently encoded in the Private Use Area (PUA) of Unicode do not have right-to-left properties. In some cases, you can correct reading order problems by inserting a Right-to-Left mark (U+200F) after the honorific ligature. These will eventually be re-encoded when they are published in Unicode 14.0.
