Coptic Capital Letter Dei

The Coptic Capital Letter Dei at U+03EE is an uppercase letter of the Coptic alphabet used for the sound and letter name dei. It is encoded in the Greek And Coptic block because modern Unicode places many Coptic letters alongside Greek-derived characters used in Coptic writing. In Coptic texts, this letter belongs to the extended set used to write the Egyptian language in its Christian-era script. It appears in editions of Coptic manuscripts, liturgical books, dictionaries, grammars, and academic transcriptions where preserving the exact traditional spelling matters. Dei also has a lowercase partner, Coptic small letter dei, used in ordinary casing distinctions in modern typography and scholarly presentation. Readers are most likely to encounter the capital form in headings, alphabet tables, word initials in edited texts, or catalog data for manuscripts and inscriptions. Because it resembles neither a common Latin letter nor most everyday Greek letters, it is mainly a specialist character for Coptic studies, church publishing, and historical linguistics. Font choice can matter in older systems or niche typefaces, since Coptic coverage is less universal than basic Greek or Latin.
