Unicode Version 17.0

U+FDA9 "ﶩ" Arabic Ligature Sad with Hah with Yeh Final Form is a typographic ligature used in the Arabic script, specifically designed to represent the combined forms of the letters Sad (ص), Hah (ح), and Yeh (ي) when they appear together at the end of a word. This character belongs to the Arabic Presentation Forms-A block and is intended for historical or specialized text rendering, such as in Quranic manuscripts or calligraphic writing, where the joined letters create a single connected glyph for aesthetic or readability purposes. It is not commonly used in modern standard Arabic digital text, as contemporary fonts typically handle such ligatures automatically through shaping rules rather than requiring a dedicated encoded character.
