U+1EEAD "𞺭" Arabic Mathematical Double-Struck Noon Unicode Character

U+1EEAD "𞺭" Arabic Mathematical Double-Struck Noon is a specialized glyph representing the Arabic letter noon (ن) in a double-struck or blackboard bold style, designed for use in mathematical and scientific notation where distinct letterforms are needed to denote specific sets, variables, or concepts. This character is part of the Arabic Mathematical Alphabetic Symbols block, which extends the Arabic script into formal mathematical contexts. It allows authors and researchers to differentiate between ordinary textual Arabic and notation used in equations, particularly in fields like algebra, number theory, or logic. The double-struck style is visually analogous to its Latin counterparts used for sets such as the natural or real numbers.
