U+FD20 "ﴠ" Arabic Ligature Khah with Yeh Final Form Unicode Character

U+FD20 "ﴠ" Arabic Ligature Khah with Yeh Final Form is a typographic ligature used in the Arabic script, specifically representing the combination of the letter Khah (خ) followed by the letter Yeh (ي) in their final positional forms as they appear at the end of a word. This character belongs to the Arabic Presentation Forms-A block, which was designed to encode contextual glyph variants and ligatures for legacy text rendering and compatibility with earlier character sets. In modern digital typography, its use is largely historical or specialized, as contemporary Arabic fonts and shaping engines can automatically generate such ligatures from standard Unicode characters without relying on these precomposed forms.
