U+037F "Ϳ" Greek Capital Letter Yot Unicode Character

U+037F "Ϳ" Greek Capital Letter Yot is a relatively recent addition to the Greek script, introduced in Unicode 7.0 in 2014 to represent the uppercase form of the archaic Greek letter yot (lowercase ϊ with diaeresis), which was used in some early Greek alphabets to denote the consonantal /j/ sound (like the English "y" in "yes"). Unlike the more familiar modern Greek letters, this character is primarily of historical and scholarly interest, appearing in linguistic texts and reconstructed inscriptions, and it is distinct from the Latin letter "J" or the Greek letter iota with a diaeresis.
