 public static void main(String[] args) {
  System.out.println(toUnicode("龙飞凤舞"));
 }
 
 public static String toUnicode(String s) {
  String as[] = new String[s.length()];
  String s1 = "";
  for (int i = 0; i < s.length(); i++) {
   as[i] = Integer.toHexString(s.charAt(i) & 0xffff);
   s1 = s1 + "\\u" + as[i];
  }
  return s1;
