U+FC91 "ﲑ" Arabic Ligature Yeh with Reh Final Form Unicode Character

U+FC91 "ﲑ" Arabic Ligature Yeh with Reh Final Form is a typographic ligature used in the Arabic script, specifically representing the combination of the letters Yeh (ي) and Reh (ر) in their final positional form, where it appears at the end of a word. This ligature is part of the Arabic Presentation Forms-A block, which was designed to support advanced typographic rendering in traditional or calligraphic contexts, though its use has largely been deprecated in favor of dynamic shaping by modern text engines. The character is encoded with a specific visual glyph that merges the two letters into a single connected shape, reflecting the cursive nature of Arabic writing and ensuring proper display in systems that require precomposed forms for legacy support.
