U+016C "Ŭ" Latin Capital Letter U with Breve Unicode Character

U+016C "Ŭ" Latin Capital Letter U with Breve is a modified Latin letter consisting of a standard uppercase U topped with a breve diacritic, a curved mark resembling a small arc. This character is primarily used in linguistic transcription systems, such as the ISO 9 standard for romanizing Cyrillic, where it represents the sound of a short or reduced u, and it appears in the orthographies of certain languages like Esperanto, where it denotes the approximant consonant /w/ as in the word "ŝtuo." Its inclusion in the Unicode standard ensures consistent digital representation across platforms for these specialized writing systems.
