C̈

C̈, c̈ in lower case, also called C with diaeresis, is a letter in the Chechen language. It represents the voiceless postalveolar affricate consonant, the same as the č in Serbo-Croatian and ç in Turkish and Albanian.

The original letter representing the voiceless postalveolar affricate consonant in Chechen was ç, but was changed to c̈ just as ş was changed to s̈.
