U+1EEA5 "𞺥" Arabic Mathematical Double-Struck Waw Unicode Character

U+1EEA5 "𞺥" Arabic Mathematical Double-Struck Waw is a specialized typographic symbol belonging to the Arabic Mathematical Alphabetic Symbols block, which was introduced in Unicode 6.1.0. This character represents the Arabic letter Waw (و) in a double-struck or blackboard bold style, typically used in mathematical and scientific contexts to denote sets, spaces, or algebraic structures in a manner analogous to how double-struck letters are used in Western mathematics for number sets. Its design mimics the thick, two-stroke appearance of blackboard bold fonts, preserving the distinctive shape of the Arabic letter while ensuring clear distinction from standard text. The character is intended for use in formal mathematical notation where Arabic script is employed, facilitating the integration of Arabic linguistic elements into modern mathematical discourse.
