U+FC84 "ﲄ" Arabic Ligature Kaf with Yeh Final Form Unicode Character

U+FC84 "ﲄ" Arabic Ligature Kaf with Yeh Final Form is a typographic ligature found in the Arabic Presentation Forms-A block, representing the joined combination of the Arabic letter Kaf (ك) and the letter Yeh (ي) in their isolated or final contextual forms within a word. This ligature, like others in its block, is primarily used for calligraphic or historic text rendering to preserve cursive fluency and aesthetic continuity, as it encodes a single glyph that seamlessly binds the two characters when they appear together at the end of a word. It is not a standard character for modern, non-formatting text processing and is instead included for compatibility with older encoding systems and specialized layout requirements.
