U+1F5D "Ὕ" Greek Capital Letter Upsilon with Dasia and Oxia Unicode Character
Unicode Version 17.0
Ὕ
U+1F5D "Ὕ" Greek Capital Letter Upsilon with Dasia and Oxia is a precomposed polytonic Greek letter that combines an uppercase Upsilon with two diacritical marks: the dasia (rough breathing), indicating an initial /h/ sound in ancient Greek, and the oxia (acute accent), which marks a high-pitched tone on that syllable. This character is primarily used in the study and transcription of classical Greek texts, where such diacritics denote breathings and pitch accents in words like the beginning of the phrase "Ὕδωρ" (water) in certain editions. It is encoded in the Unicode standard as a single character for compatibility with legacy Greek encoding systems.
