U+FB7A "ﭺ" Arabic Letter Tcheh Isolated Form Unicode Character

U+FB7A "ﭺ" Arabic Letter Tcheh Isolated Form is a typographic presentation form used primarily in Persian, Urdu, and other languages that utilize the Perso-Arabic script to represent the aspirated "ch" sound, similar to the "ch" in "church". This isolated form glyph is part of the Arabic Presentation Forms-B block, which provides context specific shapes (isolated, initial, medial, and final) for certain ligatures and letter combinations to ensure proper visual rendering in complex script environments. While standard Unicode encodes the basic letter "چ" as U+0686, U+FB7A serves as a specialized variant for systems or fonts that require explicit positional forms rather than relying on shaping engines to generate the correct appearance.
