U+1FA6 "ᾦ" Greek Small Letter Omega with Psili and Perispomeni and Ypogegrammeni Unicode Character

U+1FA6 "ᾦ" Greek Small Letter Omega with Psili and Perispomeni and Ypogegrammeni is a composite character used in ancient Greek polytonic orthography, representing a long omega vowel with three separate diacritical marks: the psili (smooth breathing) indicating no initial aspiration, the perispomeni (circumflex accent) denoting a rising and falling pitch, and the ypogegrammeni (subscript iota) marking the original presence of a long iota that became silent in later periods. This character appears primarily in ancient Greek texts, often in verb forms or nouns, to convey precise pronunciation and grammatical information that would be lost in modern monotonic Greek. It is encoded in the Unicode standard as part of the Greek Extended block, allowing for accurate digital representation and display of classical Greek manuscripts and scholarly editions.
