U+1F36 "ἶ" Greek Small Letter Iota with Psili and Perispomeni Unicode Character
U+1F36 "ἶ" Greek Small Letter Iota with Psili and Perispomeni is a precomposed polytonic Greek vowel that combines the iota letter with two ancient diacritical marks: the psili, which indicates a smooth breathing (absence of an 'h' sound) and appears as a small comma or reversed apostrophe above the letter, and the perispomeni, a circumflex accent that denotes a rising and then falling pitch in classical Greek pronunciation. This character is used in scholarly editions of ancient Greek texts, particularly in poetic or dialectal forms, to precisely represent the phonetic qualities of the iota vowel within words. It is distinct from its decomposed form, which would require combining the base letter with separate combining diacritical marks, and it appears in the Unicode block for Greek and Coptic, specifically in the range reserved for polytonic Greek.
