What ⳥ means
It marks dates in the Coptic Era of the Martyrs.
The era is also called the Diocletian Era, after Roman emperor Diocletian; its name recalls Christians killed during his persecution. Mi Ro is a monogram—a compact sign formed from letters—for a Greek phrase naming the era.
Coptic calendar notation: it supplies a date, not a conversational tone.
Read it as a date sign, not as a generic cross.
