U+1E2D "ḭ" Latin Small Letter I with Tilde Below Unicode Character

Unicode Version 17.0

U+1E2D "ḭ" Latin Small Letter I with Tilde Below is a specialized Latin script character used primarily in phonetic transcription, particularly within the International Phonetic Alphabet (IPA), to represent a creaky-voiced or laryngealized version of the vowel sound [i], often indicating a lower or non-modal phonation type. This character combines the base Latin letter i with a combining tilde placed underneath, distinguishing it from a tilde above which typically marks nasalization. Its inclusion in the Unicode Standard ensures consistent digital representation across platforms for linguists, language documentation, and academic writing where precise phonetic notation is required. The character is part of the Latin Extended Additional block and is encoded for use in fields such as phonology, dialectology, and orthography development for underrepresented languages.
