U+10C9B "𐲛" Old Hungarian Capital Letter O Unicode Character
U+10C9B "𐲛" Old Hungarian Capital Letter O is a glyph representing the letter "O" in the Old Hungarian script, an ancient writing system used by the Hungarian people before the adoption of the Latin alphabet. This capital form is part of the Old Hungarian block of Unicode and corresponds to the uppercase version of the letter used in historical inscriptions and manuscripts. It was added to the Unicode Standard in 2014 as part of a larger effort to encode and preserve the script for digital use, allowing researchers and modern speakers to represent the archaic phonetic values of the Hungarian language. The character appears stylized with angular and linear features typical of the runic style of Old Hungarian writing, distinct from the rounded shapes of Latin letters.
