U+FD31 "ﴱ" Arabic Ligature Seen with Heh Initial Form Unicode Character

U+FD31 "ﴱ" Arabic Ligature Seen with Heh Initial Form is a typographic ligature used in the Arabic script, specifically designed to represent the combination of the letters Seen (س) and Heh (ه) when they appear in their initial forms at the beginning of a word. This character is part of the Arabic Presentation Forms-A block, which contains precomposed ligatures intended for compatibility with older text rendering systems. It serves to visually bind the two letters into a single connected shape, reflecting the cursive nature of Arabic calligraphy where certain letter pairs merge seamlessly. While modern Unicode encoding typically prefers using the individual character sequence of Seen and Heh with proper shaping logic, U+FD31 remains available for specialized use in legacy documents or display contexts where the exact ligature form is required.
