PCRE has very good utf-8 support. Simply add the /u modifier to your pattern.



preg_match('/non-utf-8 matching pattern/', $string);

preg_match('/utf-8 matching pattern/u', $string);

If you switch to PCRE world functions note that pcre doesn't support UTF-8 well.



There are limitations - read "POSIX CHARACTER CLASSES" or "UNICODE CHARACTER PROPERTY SUPPORT" chapter at http://www.pcre.org/pcre.txt.

The POSIX functions are deprecated.  Instead of the "ereg" collection you want to use something from the PCRE world.
