U+1D35 "ᴵ" Modifier Letter Capital I Unicode Character

Unicode Version 17.0

U+1D35 "ᴵ" Modifier Letter Capital I is a small, superscript form of the capital letter I, belonging to the Phonetic Extensions block and primarily used in phonetic transcription systems such as the International Phonetic Alphabet or Americanist notation to indicate a secondary articulation, a reduced vowel quality, or a glide-like modification of a preceding sound. It is classified as a modifier letter, meaning it adjusts the meaning of an adjacent base character without being a full alphabetic letter itself, and because of its capital I shape, it often represents a high front unrounded vowel that is either non syllabic or part of a diphthong. This character helps linguists and language learners precisely document subtle pronunciation variations across different languages and dialects.
