U+03E7 "ϧ" Coptic Small Letter Khei Unicode Character
Unicode Version 17.0
ϧ
U+03E7 "ϧ" Coptic Small Letter Khei is a letter used in the Coptic alphabet, which was historically employed to write the Coptic language, the final stage of the Egyptian language. This character represents the sound "kh" or "χ" (a voiceless uvular fricative), similar to the "ch" in the Scottish word "loch". It is the lowercase form of the Coptic capital letter Khei, U+03E6, and is derived from the Greek letter Chi (Χ, χ) but with a distinctive hook or tilde on the right side of the vertical stroke. In modern usage, it appears in scholarly texts, liturgical contexts of the Coptic Orthodox Church, and digital fonts that support the Coptic script block.
