U+0687 "ڇ" Arabic Letter Tcheheh Unicode Character

U+0687 "ڇ" Arabic Letter Tcheheh is a distinct letter in the Arabic script, primarily used in the Sindhi and Brahui languages to represent a voiceless palato-alveolar affricate sound, similar to the "ch" in English "church." It is formed by adding three dots above the base letter "ح" (heh) and is an integral part of the extended Arabic alphabet for these South Asian languages, where it is called "tcheheh" or "cheh." This character allows for precise phonetic transcription in writing systems that require a sound not found in standard Arabic.
