passing special character to MySQL SP

[eluser]dinomycle[/eluser]
i am calling a stored procedure like below in my CI +MySQL web application

Code:

$id = 3;
        $name = "ABC_(CDE)";
$sql = "call getInfo(?,?);" ;
$query=$this->db->query($sql,array($id,$name));

but i was not getting the any query result, after enabling mysql debug, below code was getting passed to the MySQL SP

518 Query call getInfo('3','ABC_(CDE)')

so i believe the SP is searching for the string with html encoding. How to pass the variable without html encoding when i call the $this->db->query()

thanks for the help
