U+1F6C "Ὤ" Greek Capital Letter Omega with Psili and Oxia Unicode Character
Unicode Version 17.0
Ὤ
U+1F6C "Ὤ" Greek Capital Letter Omega with Psili and Oxia is a precomposed polytonic Greek letter used in classical and liturgical texts to represent a long omega vowel that begins with a smooth breathing mark, known as psili, and carries an acute accent, called oxia. This combination indicates both that the word starts with a vowel sound without an initial h sound and that the syllable is stressed with a rising pitch, as was standard in ancient Greek pronunciation. The character is a part of the Greek and Coptic block in Unicode and is encoded specifically for scholarly, theological, or historical documentation where such precise diacritical markings are required, often found in editions of Homeric epics or Byzantine manuscripts.
