U+016F "ů" Latin Small Letter U with Ring Above Unicode Character
Unicode Version 17.0
ů
U+016F "ů" Latin Small Letter U with Ring Above is a distinct letter used in the Czech and Sorbian alphabets, where it represents the sound [uː], often historically derived from a long U or from the diphthong "uo." This diacritic, a small circle placed above the letter, originated in the 15th century during the Czech orthographic reforms of Jan Hus, who introduced it to distinguish the long U sound from its short counterpart. In modern usage, "ů" appears in common Czech words like "dům" (house) and "kůň" (horse), and it is typically typed using a dedicated key on Czech keyboards or through Unicode input methods.
