Cyrillic Capital Letter U with Macron

Cyrillic Capital Letter U with Macron at U+04EE represents the uppercase form of a Cyrillic vowel letter used for a long or specially distinguished u sound. It belongs to the Cyrillic block and is a cased letter, paired with the lowercase Cyrillic u with macron. Its most visible use is in Tajik Cyrillic, where it is a regular alphabet letter and contrasts with plain У. In Tajik words such as дӯст “friend” and рӯз “day,” the lowercase form marks a distinct vowel; the capital form appears at the start of names, sentences, headings, and all-caps text. The letter is also used in some minority-language Cyrillic orthographies and scholarly transliteration systems where a macron over U signals vowel length or a separate phoneme. In dictionaries, language-learning material, passports, signs, and official documents for Tajik, it should be treated as its own letter for spelling rather than as a decorative accented variant. A practical issue is visual confusion with plain Cyrillic У in fonts or small sizes, especially when the macron is faint. Searching and sorting may distinguish Ӯ from У, so omitting the macron can change both pronunciation and lookup results in Tajik text.
