U+10C90 "𐲐" Old Hungarian Capital Letter I Unicode Character

U+10C90 "𐲐" Old Hungarian Capital Letter I is a glyph from the Old Hungarian script, also known as rovásírás, which was historically used by the Hungarian people before the adoption of the Latin alphabet. This specific character represents the capital form of the vowel sound /i/ and is part of a block added to Unicode in version 8.0 to preserve and digitally encode this ancient writing system. The letter is distinguished by its angular, runic appearance, characteristic of the script’s carved origins in wood or stone, and it appears in texts often oriented from right to left, as was typical for Old Hungarian writing.
