Set the character set

[spj-uk]

How can I set the character set? Defaults to GSM alphabet but want it to detect

$message = new \Esendex\Model\DispatchMessage(
    $source, // Send from
    $destination, // Send to any valid number
    $text,
   \Esendex\Model\Message::SmsType
  );
  $authentication = new \Esendex\Authentication\LoginAuthentication(
    $GLOBALS['EsendexAccountNo'],
    $GLOBALS['EsendexLogin'],
    $GLOBALS['EsendexPassword']     
  );
  $service = new \Esendex\DispatchService($authentication);
  $result = $service->send($message);
  print $result->id() . "\n\n";
	return $result;

I tried inserting the line
\Esendex\Model\MessageBody::CharsetAuto
after SMSType without success

As a work around I've changed the $characterSet value from null to "Auto" in DispatchMessage.php .
I'm missing a trick somewhere.
