jquery autocomplete 页面乱码

ftl 或jsp中
<link rel="stylesheet" type="text/css" href="/style/jquery.autocomplete.css" />
<script language="javascript" type="text/javascript" src="/scripts/jquery-1.2.6.pack.js"></script>
<script language="javascript" type="text/javascript" src="/scripts/jquery.autocomplete.min.js"></script>

<@ww.textfield size="20" maxlength="30" id="operators"/>

$(document).ready(function() {
           $("#operators").autocomplete("/test_result/listteloper.do?check=operators",{
			       delay:10,
			       cacheLength:1
			});
  });

action中

      StringBuffer sb = new StringBuffer();
      response.setCharacterEncoding("utf-8");  //必须
      response.getWriter().write(sb.toString());
      response.getWriter().flush();

如果通过客户端传中文值到服务器，在URL后面加上如下:
("/test_result/listteloper.do?check=operators&value=encodeURI('中文')"

记录一下，写着玩的
