Pattern Syntax - No
Unicode Version 18.0
No is the designation for characters that do not qualify as syntax characters under the Pattern Syntax rules, meaning they lack the grammatical or structural roles reserved for pattern operators, delimiters, or quantifiers. These characters are treated as ordinary content within regular expressions or string patterns, so they do not alter matching logic, grouping, or repetition behavior. The "No" value applies to letters, digits, punctuation that is not syntax-defined, whitespace, and all other code points except the specific set of symbols and punctuation marks that have been explicitly assigned syntax functions. In practice, using a "No" character in a pattern means it is interpreted literally, without any special parsing significance, making it safe for text that should be matched exactly as written.
