U+03CD "ύ" Greek Small Letter Upsilon with Tonos Unicode Character
U+03CD "ύ" Greek Small Letter Upsilon with Tonos is a distinct glyph used in modern Greek writing to represent the letter upsilon when it carries a stressed or high-pitched tone, as indicated by the acute accent mark (tonos) placed above it. This character belongs to the Greek and Coptic block of Unicode and serves a crucial role in distinguishing the pronunciation and meaning of words in standard Greek orthography, where the tonos marks the syllable that receives emphasis. It is derived from the basic Greek letter upsilon (υ) but includes the diacritical mark to fulfill the requirements of monotonic spelling, which replaced the older polytonic system in 1982. As a result, you will commonly encounter "ύ" in Greek texts, such as in the word "σύ" (you, singular), where it highlights the correct intonation for readers and speakers.
