U+03D4 "ϔ" Greek Upsilon with Diaeresis and Hook Symbol Unicode Character
Unicode Version 17.0
U+03D4 "ϔ" Greek Upsilon with Diaeresis and Hook Symbol is a specialized typographic variant of the Greek letter upsilon, combining a diaeresis (two dots) above the letter with a hook or smooth breathing mark, typically used in polytonic Greek orthography to indicate a specific pronunciation or grammatical function. It is distinct from other upsilon forms, such as the basic upsilon (Υ υ) or the upsilon with diaeresis alone (Ϋ ϋ), and was historically employed in scholarly or liturgical texts to represent a vowel that begins a word or syllable with a rough or smooth breathing, though it is rarely used in modern Greek or standard digital typography. This character, defined in the Unicode Standard as a precomposed letter within the Greek and Coptic block, serves as a historical and linguistic artifact, preserved for compatibility with legacy encoding systems and for academic transcription of ancient or medieval Greek manuscripts.
