Writing hieroglyphic text as plain text has only been supported since Unicode 12.0, so it may take a little while to explore workable encoding conventions. A significant issue is that the hieratic script is right to left but Unicode only standardises the encoding of left-to-right transcriptions. I don't recall the difference between retrograde v. normal text being declared a style difference. Use directional overrides. Those have been in the standard forever. A./ For comparison, we still have no guidance on how to encode sexagesimal Mesopotamian cuneiform numbers, e.g. '610' v. '20' written using the U graphic element. Richard.
