 * Hi there, we are receiving the following on initiating an export:
 * Fatal error: Call to undefined function mb_convert_encoding() in /home/sntryadm/
   public_html/wp-content/plugins/wp-csv/pws_wpcsv_csv.php on line 44
 * Any thoughts?
 * line 44 refers to this:
 *     ```
       $str = mb_convert_encoding( $str, $this->encoding, 'UTF-8' );
       ```

 * Hi Wimac
 * This error could mean that you don’t have the mb_string module turned on within
   your server.
 * Try talking to whoever manages your server about it. I will also make a note 
   to do better error checking and possibly provide an alternative failover method
   of converting files to UTF-8. Given current workloads, it’ll probably take me
   a week or more to get to it though.
 * Best wishes
 * Paul
