U+FEFB "ﻻ" Arabic Ligature Lam with Alef Isolated Form Unicode Character
U+FEFB "ﻻ" Arabic Ligature Lam with Alef Isolated Form is a typographic ligature representing the combination of the Arabic letters Lam (ل) and Alef (ا) in their isolated form, written as a single connected glyph. It is part of the Arabic Presentation Forms-B block and is primarily used in calligraphic or decorative writing to maintain visual harmony, particularly in formal text. This character is not considered semantically distinct from the two separate letters and is included in Unicode for compatibility with legacy fonts and systems that require a precomposed form. It is important to note that modern Unicode encoding recommends using the regular sequence of Lam and Alef (U+0644 followed by U+0627) rather than this ligature, as it can complicate text processing and searchability.
