U+FD39 "ﴹ" Arabic Ligature Sheen with Khah Medial Form Unicode Character

U+FD39 "ﴹ" Arabic Ligature Sheen with Khah Medial Form is a typographic glyph used in certain styles of Arabic script to represent a ligature of the letters sheen (ش) and khah (خ) in their medial forms, meaning they are joined within a word rather than appearing independently. This ligature is part of the Arabic Presentation Forms-A block, which contains specialized characters designed for compatibility with older text rendering systems, particularly in Quranic or calligraphic contexts. When a word requires the sequence of a medial sheen followed by a medial khah, this single character can be employed to preserve the exact visual appearance of the joined letters, though its use is not standard for general modern Arabic text, where these letters are typically typed as separate characters.
