BufferedReader br = null;
try {
           FileInputStream fileStream = new FileInputStream(path);
           byte[] arr = new byte[]{1,2,3};
           fileStream.read(arr);
           if(arr[0]==-1){
               br = new BufferedReader(
   new InputStreamReader(
    new FileInputStream(path, "UTF-16"));
            }else if(arr[0]==-17){
               br = new BufferedReader(
   new InputStreamReader(
    new FileInputStream(path, "UTF-8"));
            }else{
               br = new BufferedReader(
   new InputStreamReader(
    new FileInputStream(path));
            }
    } catch (Exception e) {
      e.printStackTrace();
