U+1F57 "ὗ" Greek Small Letter Upsilon with Dasia and Perispomeni Unicode Character
Unicode Version 17.0
ὗ
U+1F57 "ὗ" Greek Small Letter Upsilon with Dasia and Perispomeni is a precomposed polytonic Greek letter that combines a small upsilon with two ancient diacritical marks: dasia, indicating rough breathing (an initial /h/ sound), and perispomeni, a circumflex accent marking a long vowel with a rising and falling pitch. It is used in classical and liturgical Greek texts, such as in the word "ὗδωρ" (water), to accurately reflect historical pronunciation and grammatical accentuation. This character belongs to the Unicode block for Greek and Coptic (0370-03FF) and is distinct from its modern Greek counterpart, which lacks these diacritics.
