note 66394 added to function.strpos

Hello, I have strange problem. I use the strpos function and it works fine on my local server. But when I upload the file to my US server, it doesn't work well and always returns FALSE. Notice that I use strpos() to search in cyrillic strings. When I don't use cyrillic string, it works well on both servers. Isn't strpos() binary-safe? What should I do in order to make it work? ---- Server IP: 195.149.248.161 Probable Submitter: 87.126.86.136 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.strpos.php Edit -- http://master.php.net/note/edit/66394 Del: integrated -- http://master.php.net/note/delete/66394/integrated Del: useless -- http://master.php.net/note/delete/66394/useless Del: bad code -- http://master.php.net/note/delete/66394/bad+code Del: spam -- http://master.php.net/note/delete/66394/spam Del: non-english -- http://master.php.net/note/delete/66394/non-english Del: in docs -- http://master.php.net/note/delete/66394/in+docs Del: other reasons-- http://master.php.net/note/delete/66394 Reject -- http://master.php.net/note/reject/66394 Search -- http://master.php.net/manage/user-notes.php
