U+FC5B "ﱛ" Arabic Ligature Thal with Superscript Alef Isolated Form Unicode Character

U+FC5B "ﱛ" Arabic Ligature Thal with Superscript Alef Isolated Form is a presentation form character found in the Arabic Presentation Forms-A block, specifically designed for the visual representation of the Arabic letter "thal" (ذ) combined with a superscript alef (ا) as a single typographic ligature in its isolated form. This character is not intended for normal text encoding or semantic use, but rather serves as a specialized rendering variant that may appear in historical or calligraphic contexts, such as in Quranic texts or ornate manuscripts, where the superscript alef often indicates a long vowel or a grammatical marker. Its inclusion in Unicode supports the faithful digital representation of such traditional Arabic scripts, ensuring that the distinct visual appearance of this ligature is preserved in electronic documents and fonts.
