U+FC43 "ﱃ" Arabic Ligature Lam with Alef Maksura Isolated Form Unicode Character

U+FC43 "ﱃ" Arabic Ligature Lam with Alef Maksura Isolated Form is a special typographic glyph within the Arabic Presentation Forms-A block, designed to represent the combination of the Arabic letter Lam (ل) and Alef Maksura (ى) as a single connected ligature. This isolated form is used in certain styles of Arabic calligraphy and typography to enhance visual harmony and readability when these two characters appear together, particularly in medial or end-of-word positions where the Alef Maksura is not joined to a following letter. It is part of a set of presentation forms that were encoded for compatibility with legacy text-processing systems, and its use is typically aimed at preserving traditional script aesthetics rather than being essential for modern digital communication.
