C with bar

Ꞓ, minuscule: ꞓ, is a modified letter of the Latin script, formed from C with the addition of a bar. It was used in the final version of the Unified Northern Alphabet, approved in 1932 for Saami, Selkup, Khanty, Evenki, Even, Nanai, Udege, Chukchi, Koryak and Nivkh languages ^[1] to denote the sound [t͡ʃ], although in some of these languages in practice, several other alphabets were used. Also, this letter was used in the Latinized Shugnan alphabet (1931-1939) to denote the sound [t͡s].^[2][3][4]
