U+FB7E "ﭾ" Arabic Letter Tcheheh Isolated Form Unicode Character

U+FB7E "ﭾ" Arabic Letter Tcheheh Isolated Form is a presentation form variant of the Arabic letter “چ,” which represents the sound /t͡ʃ/ (like the English “ch” in “church”) and is used in scripts for languages such as Persian, Urdu, Pashto, and Kashmiri. It is encoded in the Arabic Presentation Forms-B block, specifically to represent the isolated appearance of the letter in calligraphic or text processing contexts where glyph shaping is critical. This character is distinct from the basic Arabic letter “چ” (U+0686), as U+FB7E is a positional form intended for use with other presentation forms to ensure correct visual rendering when a standard shaping engine is not available.
