ID Start - No

Unicode Version 18.0

No is a designation indicating that a character cannot begin an identifier in programming languages or text processing systems. This value applies to characters that are not letters, such as digits, punctuation marks, symbols, or control characters, which are excluded from starting a valid identifier. For example, the digit “3” or the hyphen “-” would receive a “No” value, meaning any attempt to use them as the first character of a variable, function name, or similar token would be invalid. This restriction ensures that identifiers follow consistent, predictable syntax rules, avoiding ambiguity with numeric literals or operators. The “No” value is thus a fundamental gatekeeper, defining the boundary between permissible and impermissible initial characters in lexical analysis.
