Regex Editor & Tester

This regex matches one or more consecutive characters that are not allowed in a permissive multilingual identifier set. It excludes hyphens, periods, Unicode letters and digits, as well as Hebrew (U+0590–U+05FF) and Arabic (U+0600–U+06FF) script characters. It is useful for detecting or extracting invalid segments from text that should only contain those allowed characters, such as when cleaning user input or validating filenames in multilingual contexts.
