U+2CD9 "ⳙ" Coptic Small Letter Old Coptic Dja Unicode Character

U+2CD9 "ⳙ" Coptic Small Letter Old Coptic Dja is a glyph belonging to the Coptic script block, specifically used to represent the sound /d͡ʒ/ or /t͡ʃ/ in the Old Coptic writing system, a stage of Coptic used primarily in ancient Egyptian magical and religious texts. This letter is derived from the Demotic script and was employed alongside other specially adapted characters before the standardization of the Coptic alphabet with Greek letters. It appears in historical manuscripts as part of transliterating Egyptian words that lacked a direct counterpart in the standard Greek-based Coptic set, making it a valuable resource for scholars studying Egyptological phonetics and paleography.
