U+1F77 "ί" Greek Small Letter Iota with Oxia Unicode Character
Unicode Version 17.0
ί
U+1F77 "ί" Greek Small Letter Iota with Oxia is a precomposed character representing the Greek letter iota combined with the oxia accent, which historically indicates a rising pitch in Ancient Greek. This character is part of the Greek Extended block and is used in polytonic Greek orthography, primarily for scholarly, liturgical, or historical texts that require accentuation beyond the modern monotonic system. The oxia appears as a distinct acute-like mark above the iota, distinguishing it from the simpler combination of iota with a tonos, though in practice the oxia and tonos are often visually identical in modern fonts.
