U+FDD6 "﷖" Arabic Presentation Forms-A Unicode Character

U+FDD6 "﷖" Arabic Presentation Forms-A is a rarely used compatibility character that represents a specific Arabic ligature, formed by combining the letters for "all" (alif lam lam) and a subjoined "ha" or similar element, though its exact graphical identity and intended usage are not clearly documented in standard codepoint lists. It belongs to the Arabic Presentation Forms-A block, which contains a collection of contextual glyph variants and ligatures primarily designed for backward compatibility with older Arabic text rendering systems, particularly in legacy fonts or early digital typesetting where automatic ligation was not available. This character is non-spacing in principle and is considered a presentation form rather than a core encoding unit for modern Arabic text, meaning it is typically avoided in contemporary Unicode text in favor of the standard Arabic letter sequence that a compliant shaping engine can process automatically.
