Phonegap Android推送通知非英文字符无法正确显示

我正在使用 Phonegap Push Plugin 将push notification 发送到设备 . 发送英文字符时一切都很好 . 但是当我尝试发送缅甸（UTF-8）字符时，它不起作用 . 字符显示如下： <p>&#4145;&#4141;&#4141;</p> . 服务器部分是 PHP . 下面是我的通知的java代码（实际上是来自 Phonegap Push Plugin ）：

public void createNotification(Context context, Bundle extras)
{
    NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    String appName = getAppName(this);

    Intent notificationIntent = new Intent(this, PushHandlerActivity.class);
    notificationIntent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
    notificationIntent.putExtra("pushBundle", extras);

    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    int defaults = Notification.DEFAULT_ALL;

    if (extras.getString("defaults") != null) {
        try {
            defaults = Integer.parseInt(extras.getString("defaults"));
        } catch (NumberFormatException e) {}
    }

    NotificationCompat.Builder mBuilder =
        new NotificationCompat.Builder(context)
            .setDefaults(defaults)
            .setSmallIcon(context.getApplicationInfo().icon)
            .setWhen(System.currentTimeMillis())
            .setContentTitle(extras.getString("title"))
            .setTicker(extras.getString("title"))
            .setContentIntent(contentIntent)
            .setAutoCancel(true);

    String message = extras.getString("message");

    if (message != null) {
        mBuilder.setContentText(message);
    } else {
        mBuilder.setContentText("<missing message content>");
    }

    String msgcnt = extras.getString("msgcnt");
    if (msgcnt != null) {
        mBuilder.setNumber(Integer.parseInt(msgcnt));
    }

    int notId = 0;

    try {
        notId = Integer.parseInt(extras.getString("notId"));
    }
    catch(NumberFormatException e) {
        Log.e(TAG, "Number format exception - Error parsing Notification ID: " + e.getMessage());
    }
    catch(Exception e) {
        Log.e(TAG, "Number format exception - Error parsing Notification ID" + e.getMessage());
    }

    mNotificationManager.notify((String) appName, notId, mBuilder.build());
}
