U+FCB1 "ﲱ" Arabic Ligature Sad with Hah Initial Form Unicode Character

U+FCB1 "ﲱ" Arabic Ligature Sad with Hah Initial Form is a typographic variant used in Arabic script, specifically representing a ligature, or joined form, of the letters Ṣād (ص) and Ḥā’ (ح) when they appear at the beginning of a word. In the Arabic writing system, letters change shape depending on their position within a word, and this character encodes the initial form of this two-letter combination, where the Ṣād takes its initial shape and is seamlessly connected to the following Ḥā’. This ligature is part of the Arabic Presentation Forms-B block in Unicode, which exists to support traditional and calligraphic text rendering that requires precomposed glyphs for historical or stylistic accuracy, rather than relying on modern dynamic shaping rules.
