The latest version of the complete perlfaq is at http://faq.perl.org . -------------------------------------------------------------------- 6.8: How can I match a locale-smart version of "/[a-zA-Z]/"? You can use the POSIX character class syntax "/[[:alpha:]]/" documented in perlre. No matter which locale you are in, the alphabetic characters are the characters in \w without the digits and the underscore. As a regex, that looks like "/[^\W\d_]/". Its complement, the non-alphabetics, is then everything in \W along with the digits and the underscore, or "/[\W\d_]/". -------------------------------------------------------------------- The perlfaq-workers, a group of volunteers, maintain the perlfaq.
