U+0109 "ĉ" Latin Small Letter C with Circumflex Unicode Character
Unicode Version 17.0
ĉ
U+0109 "ĉ" Latin Small Letter C with Circumflex is a distinct letter used in several languages, most notably in Esperanto, where it represents a voiceless postalveolar affricate sound, similar to the "ch" in English "cheese". This diacritical mark, the circumflex, modifies the base Latin letter C to indicate a different phonetic value that is critical to proper pronunciation and meaning in those writing systems. Beyond Esperanto, it also appears in some orthographies for other languages, such as in the transliteration of certain Slavic or Baltic words, and is part of the Latin Extended-A block of the Unicode standard, ensuring its proper digital representation across different platforms and text systems.
