U+04E4 "Ӥ" Cyrillic Capital Letter I with Diaeresis Unicode Character
Unicode Version 17.0
Ӥ
U+04E4 "Ӥ" Cyrillic Capital Letter I with Diaeresis is a variant of the Cyrillic letter I, distinguished by the addition of a diaeresis (two dots) above it, which indicates a specific phonetic modification in certain languages. This character is primarily used in the Udmurt language, a Uralic language spoken in the Udmurt Republic of Russia, where it represents a close central unrounded vowel sound, similar to the 'y' in the English word "myth" but with more precision. It should not be confused with the similar-looking Latin letter I with diaeresis, as it belongs to the Cyrillic script block and has a distinct code point separate from other characters like the Cyrillic letter Yi (Ї).
