Pattern Syntax - Yes

Unicode Version 18.0

Yes is the designation for characters that Unicode officially recognizes as valid syntax elements within regular expression patterns, meaning they are permitted to appear as literals or operators in pattern definitions without needing escaping. This value applies to a specific set of punctuation marks, such as brackets, parentheses, asterisks, plus signs, question marks, and backslashes, which have well defined roles in pattern matching logic. Characters marked with "Yes" are excluded from being treated as ordinary text in such contexts, ensuring that pattern parsers can reliably interpret their intended function. This designation helps distinguish syntactically active symbols from those that are purely content characters, providing a consistent baseline for regex engines across different programming languages and tools.
