U+1FD6 "ῖ" Greek Small Letter Iota with Perispomeni Unicode Character

Unicode Version 17.0

U+1FD6 "ῖ" Greek Small Letter Iota with Perispomeni is a precomposed character from the Greek Extended block, representing the lowercase Greek letter iota (ι) combined with a perispomeni diacritic, which historically marks a circumflex accent in ancient Greek orthography. This accent indicates a specific pitch contour, typically a rising and then falling tone, on the vowel in polytonic Greek texts. The character is primarily used in scholarly, liturgical, and historical writing to accurately preserve ancient Greek pronunciation and grammatical distinctions, and it should not be confused with similar-looking characters like the iota with tonos, as the perispomeni has a distinct shape and function in polytonic scripts.
