U+FC3E "ﰾ" Arabic Ligature Kaf with Yeh Isolated Form Unicode Character

Unicode Version 17.0

ﰾ

U+FC3E "ﰾ" Arabic Ligature Kaf with Yeh Isolated Form is a typographic ligature used in the Arabic script, specifically representing the visual combination of the letters Kaf (ك) and Yeh (ي) when they occur together in their isolated forms. This character belongs to the Arabic Presentation Forms-A block, which was primarily designed for compatibility with legacy text processing systems that required precomposed glyphs rather than relying on modern font rendering engines. The ligature appears as a single cursive glyph where the tail of the final Yeh merges seamlessly with the preceding Kaf, preserving the calligraphic flow essential to written Arabic. While such ligatures are less commonly needed in contemporary Unicode text, U+FC3E remains available for use in contexts that demand exact visual representation of historical or stylized typography.
