U+04F0 "Ӱ" Cyrillic Capital Letter U with Diaeresis Unicode Character
Unicode Version 17.0
Ӱ
U+04F0 "Ӱ" Cyrillic Capital Letter U with Diaeresis is a modified version of the standard Cyrillic letter U (У) that includes a diaeresis, or two dots, placed above it. This character is used in several languages that utilize the Cyrillic script, such as Khakas, Altai, and Mari, to represent a distinct vowel sound, typically a fronted or rounded [y] sound similar to the German ü or the French u. It serves as a separate letter in these alphabets, differentiating words and meanings where the plain U would not suffice, and it is encoded in the Unicode standard to ensure proper digital representation and text processing across computing systems.
