Try this:

1. accept the user's input
2. store using url_title();
3. retrieve and display using str_replace('-', ' ' , $username);
 
If the user inputs a dash then this will remove the displayed dash.

This requires further logic but at least it's a start

Use a callback

Code:

$this->form_validation->set_rules('username', 'Username', 'trim|required|valid_email|callback_username_check_blank|xss_clean');

function username_check_blank($str)
{

    $pattern = '/ /';
    $result = preg_match($pattern, $str);

    if ($result)
    {
        $this->form_validation->set_message('username_check', 'The %s field can not have a " "');
        return FALSE;
    }
    else
    {
        return TRUE;
    }
}
