U+04F1 "ӱ" Cyrillic Small Letter U with Diaeresis Unicode Character

U+04F1 "ӱ" Cyrillic Small Letter U with Diaeresis is a variant of the Cyrillic letter U with an umlaut or diaeresis mark above it, used primarily in certain non-Slavic languages that employ the Cyrillic script, such as Khanty, Komi, and Altai, to represent a specific fronted or centralized vowel sound distinct from the plain U. It is encoded in the Cyrillic block of Unicode and is the lowercase form corresponding to the uppercase version U+04F0 "Ӱ". This letter appears in linguistic contexts where precise vowel articulation is necessary, and it is often romanized as "ü" or "iu" to reflect its pronunciation. The diaeresis indicates that the vowel should be pronounced separately from a preceding vowel or, more commonly, that it has a modified quality, typically a front rounded vowel like the German ü.
