U+FC18 "ﰘ" Arabic Ligature Hah with Meem Isolated Form Unicode Character

U+FC18 "ﰘ" Arabic Ligature Hah with Meem Isolated Form is a typographic ligature found within the Arabic Presentation Forms-A block, designed to represent the combined shape of the Arabic letters Hah (هـ) and Meem (م) when they appear consecutively in their isolated form, meaning without connection to other characters on either side. This ligature is primarily intended for backward compatibility with older Arabic text rendering systems, where such precomposed forms were used to simplify display, and it represents a single character rather than two separately typed letters. While modern Unicode text typically prefers to encode the sequence of Hah and Meem as individual characters with contextual shaping by a font, U+FC18 preserves the historical appearance of this specific ligature for digital texts that require exact visual representation from legacy encodings.
