U+FDAA "ﶪ" Arabic Ligature Sheen with Hah with Yeh Final Form Unicode Character

Unicode Version 17.0

U+FDAA "ﶪ" Arabic Ligature Sheen with Hah with Yeh Final Form is a typographic presentation form used in certain styles of Arabic script, specifically for rendering the letters sheen (ش), hah (ح), and yeh (ي) as a single, connected glyph when they appear in the final position of a word. This ligature is part of the Arabic Presentation Forms-A block, which exists to accommodate historical or stylistic calligraphic conventions, but it is generally not required for standard text processing, as modern Unicode text can represent the same sequence by typing the letters individually. Its use is primarily in high-quality typesetting or digital reproductions of classical manuscripts where such cursive flourishes are preferred.
