Test, validate and match regular expressions
This regex captures Korean insurance product names that begin with '(무)' (marking a non-dividend/무배당 policy), followed by 3 or more Korean characters (가-힣), letters, digits, spaces, hyphens, parentheses, ampersands, periods, or commas, ending with a closing parenthesis, followed by a literal '\x0b' escape (vertical tab marker). It is designed for extracting insurance product names from Korean insurance documents, PDFs, or text dumps where names follow this conventional format. The gm flags enable matching multiple occurrences across multiple lines.
