U+04C4 "ӄ" Cyrillic Small Letter Ka with Hook Unicode Character

U+04C4 "ӄ" Cyrillic Small Letter Ka with Hook is a modified letter from the Cyrillic script, specifically derived from the standard Cyrillic letter Ka (К, к) by adding a hook to its bottom right side, which is used to represent a voiceless uvular plosive sound in various indigenous languages of Siberia and the Russian Far East, such as Itelmen, Koryak, and Chukchi. It corresponds to the capital form U+04C3 "Ӄ" and is distinct from other hooked Cyrillic letters like Ka with descender or Ka with stroke, serving as a crucial orthographic tool for accurately transcribing the phonetic systems of these endangered languages in linguistic documentation and modern writing.
