U+2CC7 "ⳇ" Coptic Small Letter Old Coptic Esh Unicode Character

U+2CC7 "ⳇ" Coptic Small Letter Old Coptic Esh is a glyph representing a specific archaic consonant sound from the Old Coptic script, a stage of the Coptic alphabet used before the standardization of the classical Coptic writing system. This letter corresponds to the sound "š" (like the English "sh") and is historically derived from a Demotic Egyptian source, not directly from the Greek alphabet as most standard Coptic letters are. It appears primarily in ancient magical, liturgical, and religious texts, where it was employed to preserve phonetic distinctions that later Coptic dialects eventually merged or lost. As a seldom-used character, it is now part of the Coptic Unicode block to support accurate digital representation of these historical manuscripts.
