It gets better: this glyph is bugged. Somehow, the guy responsible for adding it to Unicode somehow got the number of eyes wrong. Per his description, Unicode fonts represent it with 7 eyes, but after getting called out on Twitter he realized the original manuscript shows 10 eyes.
What about modern uses of the character that specifically intended 7 eyes? Unicode needs to add a time or (worse, but probably OK) version datum to glyphs or glyph ranges, I suppose (applying it only at the document level wouldn't suffice, as in the case of quoting).
This bug will be fixed in Unicode 15.
