title: Session issue in codeigniter for arabic character
body: <p>I am just stuck with a issue regarding session. I have a multilingual ecommerce site for english and arabic language. In case of arabic language when someone registers with a arabic name, description or such fields s/he can register successfully. But during login the session data being lost.</p>
  
  <p>Actually when setting all the data into a session array its being stored and i tested it by printing the array. But after the valid authentication when user being redirected to index page or profile page then the session array disappears. The full array being lost. and login doesnt working. Its only happening for someone who has arabic fields on their data. for english its perfectly ok. </p>
  
  <p>I have removed the session.php from syatem/libraries directory. Then it works only on localhost, on server it creates problem when ordering or viewing items of a particular org.</p>
  
  <p>Any suggestion will be accepted cordially.</p>
  
  <p>Thanks</p>
