Thread:Project:Support desk/Install error Warning: preg replace() function.preg-replace : Compilation failed: this version of PCRE is not compiled with PCRE UTF8 support at offset 0 in /var2/mediawiki-1.16.0/includes/Title.php on line 2285/reply (11)

I am getting a similar error. I copied this code <?php echo preg_replace( '/[\x{0430}-\x{04FF}]/iu', '', '-АБВГД-' ); into a text file and saved it as test.php in UTF-8 encoding. Moved it into my webserver directory and changed permission. Ran it but nothing is displayed.
