Edit Question
Title
Body
I'm already aware that \w in PCRE (particularly PHP's implementation) can sometimes match some non-ASCII characters depending on the locale of the system, but what about [a-z] ? I wouldn't think so, but I noticed these lines in one of Drupal's core files (includes/theme.inc, simplified): // To avoid illegal characters in the class, // we're removing everything disallowed. We are not using 'a-z' as that might leave // in certain international characters (e.g. German umlauts). $body_classes[] = preg_replace('![^abcdefghijklmnopqrstuvwxyz0-9-_]+!s', '', $class); Is this true, or did someone simply get [a-z] confused with \w ?
