U+1EEBA "𞺺" Arabic Mathematical Double-Struck Zah Unicode Character

Unicode Version 17.0

𞺺

U+1EEBA "𞺺" Arabic Mathematical Double-Struck Zah is a specialized character belonging to the Arabic Mathematical Alphabetic Symbols block, which is used primarily in mathematical and scientific notation rather than general Arabic text. It represents the Arabic letter "Zah" (ظ) in a double-struck or blackboard bold style, a typographic variant often employed to denote specific number sets, abstract algebraic structures, or other mathematical objects in Arabic-script mathematics. This character is designed for compatibility with mathematical expressions where a bold, doubled outline is required to distinguish it from regular letters, and its inclusion in Unicode supports the encoding of formal mathematical documents in languages that use the Arabic script.
