Hi,
I'm facing an issue with preg_match and an UTF8 string.
The pattern is : /^[[:alnum:]\s\-\'%]+$/u
The string : Régis
If I read the manual preg_match should return 0 ("In UTF-8 mode, characters with values greater than 128 do not match any of the POSIX character classes.") but I've got 1 in some case :
On a Windows host
php 5.2.12 - (PCRE 7.9 2009-04-11) : preg_match === 1
On the same centos host :
php 5.2.10 (Rémi's RPM) - (PCRE 6.6 06-Feb-2006) : preg_match === 0
php 5.4.8 (my build) - (PCRE 8.12 2011-01-15) : preg_match === 1
On an other Centos host :
php 5.4.0 (Rémi's RPM) - (PCRE 7.8 2008-09-05)
How this can be possible ?
Regards,
