U+FD1A "ﴚ" Arabic Ligature Sheen with Yeh Final Form is a typographic ligature used in the Arabic script, specifically representing the combination of the letter Sheen (ش) and the letter Yeh (ي) in their final forms as they appear at the end of a word. This character belongs to the Arabic Presentation Forms-A block and is designed for compatibility with older text rendering systems, where such ligatures were common for aesthetic or practical spacing reasons.
