Math - No
No is used to indicate that a character does not possess mathematical semantic meaning, meaning it is not intended for use in mathematical notation, formulas, or symbolic reasoning. This includes ordinary letters, digits, punctuation, and control characters that function in general text, as well as symbols like currency signs or emoji. When a character has the No value, it is treated as purely textual or typographical, without any implied algebraic, geometric, or logical function. This distinction helps software correctly render and interpret content, ensuring that mathematical processing is applied only to characters explicitly designed for that purpose. The No value is the default for the vast majority of Unicode characters, reserving mathematical classification for a specific, curated set of symbols and operators.
