U+1FF6 "ῶ" Greek Small Letter Omega with Perispomeni Unicode Character
U+1FF6 "ῶ" Greek Small Letter Omega with Perispomeni is a precomposed polytonic Greek letter that combines the lowercase omega with a perispomeni (circumflex accent) diacritic, historically used to indicate a specific pitch contour in ancient Greek pronunciation. This character is part of the Greek Extended block in Unicode, designed to support the writing of Ancient Greek texts with polytonic orthography. The perispomeni mark, which resembles a tilde or inverted breve placed over the vowel, signifies a high-low or falling tone pattern on the omega as required by classical Greek accentuation rules. As a precomposed form, U+1FF6 provides a convenient single-codepoint representation, allowing for easier text processing and rendering when displaying accurate ancient Greek phrases or scholarly works that necessitate precise diacritical markings.
