发短信中文乱码,该如何处理

发短信中文乱码
当是cdma时，中文显示乱码为：“？？？？？？？？？？”
if (isCDMA()) {
            DatagramConnection dgConn = null;
            try {
                dgConn = (DatagramConnection) Connector.open("sms://" + number);
                byte[] data = content.getBytes();
                Datagram dg = dgConn.newDatagram(dgConn.getMaximumLength());
                dg.setData(data, 0, data.length);
                dgConn.send(dg);
                Thread.sleep(SLEEP_SMS);
            } catch (IOException e) {
                System.out.println("sendSMS--->CDMA--->" + e.getMessage());
            } catch (InterruptedException e) {
                System.out.println("sleepInterrupted--->" + e.getMessage());
            } finally {
                if (dgConn != null)
                    try {
                        dgConn.close();
                    } catch (IOException e) {
                        System.out.println("sendSMS---finally--->" + e.getMessage());
                    }
            }
        }
