U+1FFB "Ώ" Greek Capital Letter Omega with Oxia Unicode Character
Unicode Version 17.0
Ώ
U+1FFB "Ώ" Greek Capital Letter Omega with Oxia is a precomposed character used in polytonic Greek orthography to represent the long vowel omega with an acute accent, known as an oxia, which indicates a high pitch in ancient Greek pronunciation. This character is part of the Greek Extended block in Unicode and is typically used in scholarly or liturgical texts where the traditional Greek accent system is preserved. It is distinct from the more common Greek capital omega with tonos (U+038F) in modern Greek, as the oxia is a historical accent mark that predates the modern monotonic system.
