中文编码问题

Question

我把主要的信息放在下面
function startExplore(HeroID, HeroName, HeroPic){
        document.getElementById("startExplore").style.display = "block";
        document.getElementById("showExploreInfo").style.display = "none";
        document.getElementById("heroID").value = HeroID;
        document.getElementById("heroName").value = HeroName;      
        document.getElementById("heroPic").src = "skin/hero/heroList/" + HeroPic;
        parent.document.all('IframePage').height = 900;
  }
...
          <tr>
                  <td>.........</td>
                  <td>.....................</td>
                  <td><img src="skin/Adventure/beginExploreBtn.jpg" onclick="startExplore(270085,'.........','1_1z.jpg')"/></td>
          </tr>
                    
          <tr>
                   <td>...............</td>
                   <td>.....................</td>
                   <td><img src="skin/Adventure/beginExploreBtn.jpg" onclick="startExplore(270086,'...............','2_1z5.jpg')"/></td>
           </tr>
                    
           <tr>
                   <td>...............</td>
                   <td>.....................</td>
                   <td><img src="skin/Adventure/beginExploreBtn.jpg" onclick="startExplore(270087,'...............','3_1.jpg')"/></td>
           </tr>
...    <form name="exploreForm" action="heroExplore.cfm" method="post">
                             <div id="sel_exploreType">........................
                         
                            <input type="hidden" value="" id="heroID" name="heroID" />
                            <input type="hidden" value="" id="heroName" name="heroName" />        
                           <input type="hidden" value="startExplore" name="eflag" />
                           <input type="hidden" value="heroExplore" name="page" />
                            <input name="exploreType" type="radio" style="background:none" value="1" checked="checked" />
                        </div>
                         <div id="submitDiv"><input type="image" src="skin/Adventure/submitBtn.jpg" name="submit" style="border:0px;" /></div>
                         </form>
            
                    
这个是主要的几个函数   
我的问题是如何在这些信息中换取heroname的信息呢
抓包后  发现post了这些信息,其他的信息怎么得到的我都高清楚了 就是这个heroname 因为是用中文的 搞不懂了,望大家帮个忙
heroID=270085&heroName=%E6%9D%A8%E5%81%A5%E7%BE%8E&eflag=startExplore&page=heroExplore&exploreType=1&submit.x=37&submit.y=9
