U+1F56 "ὖ" Greek Small Letter Upsilon with Psili and Perispomeni Unicode Character
U+1F56 "ὖ" Greek Small Letter Upsilon with Psili and Perispomeni is a polytonic Greek letter that combines the vowel upsilon (υ) with two diacritical marks: a psili (ἀ, representing a smooth breathing mark) and a perispomeni (῀, indicating a circumflex accent on a long vowel). This character is historically used in ancient and liturgical Greek texts to denote specific pronunciation and grammatical nuances, where the psili shows there is no initial aspiration and the perispomeni marks a rising and falling pitch on the same syllable. It is part of the Unicode block for Greek and Coptic, encoding a form of upsilon that appears in scholarly editions of classical works and religious manuscripts, preserving the detailed accentuation system of classical philology.
