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

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.

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.
