What Ⲷ means
A cipher substitute for ordinary Coptic Eie Ⲉ. “Cryptogrammic” means used in a cipher. Frequent Eie could reveal the substitution pattern, so Ⲷ took its place.
Coptic cipher writing appears in magical texts from Roman and Byzantine Egypt.
Use it in Coptic cipher discussions, not as a general secret-code symbol.
Keep Ⲷ distinct from Ⲉ until the cipher is decoded.

1Why does Ⲷ show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
