XID Start - No

Unicode Version 18.0

No is the identifier that marks characters which cannot begin a valid identifier in programming languages, such as digits, punctuation marks, symbols, and most whitespace or control characters. This value applies to code points that are not considered suitable for the first position of a variable, function, or class name, even if they might be allowed later in the identifier. Examples include ASCII digits like 0 through 9, hyphens, apostrophes, and emoji. The designation reflects a character’s structural role in syntax, not its semantic meaning, and it ensures that parser rules consistently reject ambiguous or positionally invalid starts. In practice, this value is assigned to the vast majority of Unicode code points, including all letters that require modification or combination with other characters, as well as all non-alphabetic scripts that do not follow the standard letter pattern for initial positions.
