U+0370 "Ͱ" Greek Capital Letter Heta Unicode Character

U+0370 "Ͱ" Greek Capital Letter Heta is a historical letter of the Greek alphabet that was used in some early local scripts, particularly in the western Greek dialects, to represent a breathy or aspirated sound similar to the /h/ sound. It is visually distinctive as a half of the uppercase eta, resembling a leftward hook or a semicircle, and it served as a precursor to the later rough breathing mark (῾) in Greek orthography. This character is now considered archaic, having been replaced by the standard Greek alphabet and the breathing marks that evolved from it.
