U+FC57 "ﱗ" Arabic Ligature Yeh with Khah Isolated Form Unicode Character

U+FC57 "ﱗ" Arabic Ligature Yeh with Khah Isolated Form is a typographic ligature used in the Arabic script, specifically representing the combination of the letters Yeh (ي) and Khah (خ) as a single, isolated glyph. This character is part of the Arabic Presentation Forms-A block, which was designed for compatibility with older text processing systems that required precomposed forms of common letter pairs. It is used in contexts where the sequence of Yeh followed by Khah appears in its isolated position, meaning it is not connected to letters on either side, and its primary purpose is to ensure proper visual rendering in certain legacy fonts and digital environments.
