U+1F7B "ύ" Greek Small Letter Upsilon with Oxia Unicode Character
Unicode Version 17.0
ύ
U+1F7B "ύ" Greek Small Letter Upsilon with Oxia is a precomposed character used in polytonic Greek, combining the lowercase Greek letter upsilon (υ) with an oxia (´), a diacritical mark that indicates a high pitch accent in Ancient Greek. This specific character is part of the Greek Extended block and is typically employed in scholarly texts, liturgical writings, or linguistic transcriptions to accurately represent the accented vowel sound in words like "αὐτῇ" (meaning "to her"). The oxia, historically derived from the acute accent, helps distinguish pitch patterns in classical pronunciation, though in modern usage it is often replaced by the tonos in monotonic orthography.
