U+FB89 "ﮉ" Arabic Letter Ddal Final Form Unicode Character

U+FB89 "ﮉ" Arabic Letter Ddal Final Form is a presentation form of the Arabic letter Ddal used exclusively in the final position of a word when rendered in certain Arabic scripts, such as Naskh or Nastaliq. It represents the letter ظ (ẓā’), which is a pharyngealized voiced dental fricative, and this specific glyph is designed to connect smoothly to preceding letters while featuring a distinctive tail that curves downward and to the left. This character is part of the Arabic Presentation Forms-A block, which contains contextual variants to ensure proper typographic shaping in complex text layouts, though modern fonts often rely on dynamic shaping algorithms rather than these precomposed forms.
