U+038A "Ί" Greek Capital Letter Iota with Tonos Unicode Character
Unicode Version 17.0
Ί
U+038A "Ί" Greek Capital Letter Iota with Tonos is a typographic symbol representing the Greek letter Iota in its uppercase form, combined with a stress mark known as a tonos, which indicates a high or stressed tone in modern Greek pronunciation. Found in the Greek and Coptic block of Unicode, this character is distinct from the similar-looking Latin letter I or the combining accent sequences, as it is a precomposed character used specifically for written Greek to denote emphasis on the vowel Iota at the beginning of a word or syllable, such as in the word "Ία" (a name or exclamation). Its inclusion in digital text ensures proper rendering and linguistic accuracy for Greek speakers and scholars working with electronic documents.
