Re: Check if PCRE has UTF-8 support compiled in

Nuno Lopes, Thanks a lot! I was able to resolve the issue! Odd enough, POSIX named classes (eg [:alnum:] are not supported either when PCRE is not compiled with UTF-8 and Unicode support. Which is weird, because the manual states elsewise. For those of you interested to see the fix, please refer to: http://framework.zend.com/fisheye/browse/Zend_Framework/trunk/library/Zend/Filter/Alnum.php?r=5468 Nuno, thanks again!
