Cyrillic Small Letter U with Double Acute

Cyrillic Small Letter U with Double Acute at U+04F3 is a Cyrillic letter used to write a front rounded vowel, roughly like the sound of German ü in many descriptions. It belongs to the Cyrillic block and is a lowercase form paired with the corresponding capital letter used in the same alphabets. Its main real-world use is in minority-language Cyrillic orthographies of the Volga-Ural region, especially Chuvash, where it represents a distinct vowel phoneme rather than a decorated Russian у. It appears in ordinary Chuvash words, names, dictionaries, school materials, and local publications, so changing it to plain у can change spelling and pronunciation. The letter may also occur in linguistic writing, transliteration tables, and language-learning materials that discuss Chuvash or related Cyrillic-based alphabets. Readers should not confuse it with Latin u plus accent marks or with Cyrillic у followed by separate combining accents; in searchable text and fonts, the precomposed Cyrillic letter is the standard character intended here.
