U+012E "Į" Latin Capital Letter I with Ogonek Unicode Character
Unicode Version 17.0
Į
U+012E "Į" Latin Capital Letter I with Ogonek is a modified form of the standard I used primarily in Lithuanian and some other languages, where the ogonek (a hook-shaped diacritic attached beneath the letter) indicates a nasalized vowel sound. In Lithuanian orthography, it represents a long, back, or historically nasalized vowel, contrasting with the plain I, and it appears in words such as "Įdomus" (meaning "interesting"). The character is also employed in the transliteration of certain Indigenous languages and occasionally in medieval Latin manuscripts, though its most consistent and official use remains within the Lithuanian alphabet.
