  If I do not set PuTTY any thing（the default "Use font encoding"）, the split line of pane shows like following:

  <p>But it can't show Chinese word correctly, so I set PuTTY's Window -> Translation -> Remote character set to UTF-8. Then the split line of pane become to like that:

  <p>Using “xxx qqqq” seems very ugly.</p>
  
  <p>BTW: echo $LANG shows “zh_CN.UTF-8”</p>
  
  <p>So, in this case, How to show Chinese word correctly with the first split line?</p>
