Hi guys,

Given the test case below, some UDC are printed out. With some native test case on windows, the result is expected to be:
\ue585\ue586\ue592 ->   \xa2\xa0\xa3\x40\xa3\x4c
But got:
\ue585\ue586\ue592 ->   \xa2\xa0\xa2\xab\xa3\x40

Are there any specs to clearify these differences? Are the differences expected?

import  java.nio.*;
import  java.nio.charset.*;

class zhPUATest {
   public  static  void main(String[] args)throws  Exception {
     for(String  cname :new  String[]{"MS936"}) {
       Charset charset = Charset.forName(cname);
       CharsetEncoder ce = charset.newEncoder();
       char[] chars =new  char[]{0xE585, 0xE586, 0xE592};
       CharBuffer cb = CharBuffer.wrap(chars);
       ByteBuffer bb = ce.encode(cb);

       for(char  c : chars)  {
            System.out.print(" ->   ");

       for(byte  b : bb.array())if  (b != 0x0) {
           System.out.printf("\\x%02x",(int)b&   0xFF);
