U+016E "Ů" Latin Capital Letter U with Ring Above Unicode Character
Unicode Version 17.0
Ů
U+016E "Ů" Latin Capital Letter U with Ring Above is a specialized letter used primarily in the Czech language, where it represents a long /uː/ sound that is pronounced with the lips more rounded than a standard U. This glyph appears in words such as "dům" meaning house and "kůň" meaning horse, and it is distinct from the similar-looking "U with breve" or "U with diacritic" found in other scripts. The ring above the letter functions as a diacritic that modifies pronunciation rather than serving as an ornamental mark, and it has a corresponding lowercase form (ů) at code point U+016F. Historically, this character evolved from the digraph "uo" in Old Czech, with the ring symbolizing the former 'o' that became part of the modern long vowel.
