The Wikipedia has the following information about this codepoint:
Ç or ç (C-cedilla) is a Latin script letter used in the Albanian, Azerbaijani, Manx, Tatar, Turkish, Turkmen, Kurdish, Kazakh, and Romance alphabets. Romance languages that use this letter include Catalan, French, Portuguese, and Occitan, as a variant of the letter C with a cedilla. It is also occasionally used in Crimean Tatar and in Tajik (when written in the Latin script) to represent the /d͡ʒ/ sound. It is often retained in the spelling of loanwords from any of these languages in English, Basque, Dutch, Spanish and other languages using the Latin alphabet.
It was first used for the sound of the voiceless alveolar affricate /t͡s/ in Old Spanish and stems from the Visigothic form of the letter z (Ꝣ). The phoneme originated in Vulgar Latin from the palatalization of the plosives /t/ and /k/ in some conditions. Later, /t͡s/ changed into /s/ in many Romance languages and dialects. Spanish has not used the symbol since an orthographic reform in the 18th century (which replaced ç with the now-devoiced z), but it was adopted for writing other languages.
In the International Phonetic Alphabet, /ç/ represents the voiceless palatal fricative.
