ID Compat Math Continue - No
No is the designation for characters that are not permitted to continue a mathematical identifier under the rules for compatibility math continuation. This value applies to the vast majority of Unicode characters, including all letters, digits, punctuation, symbols, and whitespace that lack a specific compatibility mapping or a defined mathematical continuation role. Essentially, any character that does not function as a valid extension of a mathematical identifier, such as a combining mark with a math-specific property or a compatibility-derived character, receives this default assignment. It ensures that only explicitly recognized characters can be used in the middle of such identifiers, preventing ambiguous or unintended continuations. Thus, No represents the standard, exclusionary state for nearly all code points.
