U+FD2B "ﴫ" Arabic Ligature Sad with Reh Final Form Unicode Character

U+FD2B "ﴫ" Arabic Ligature Sad with Reh Final Form is a typographic composite glyph used in the Arabic script, representing a ligature that combines the letters sad (ص) and reh (ر) into a single connected form, specifically designed to appear at the end of a word. This character belongs to the Arabic Presentation Forms-A block, which contains various contextual forms and ligatures for calligraphic and historical text rendering, and it is primarily employed in traditional or stylized writings rather than in modern standard digital typography. Its usage ensures that the cursive fluidity of Arabic calligraphy is preserved when the sad and reh join in their final positional shapes, where the sad takes its end form and the reh appears as a continuous tail.
