Text* Snippets: javascript code

I got this mostly working - the only thing that sucks is encoding of non-ascii characters like �, �, etc... I've tried escape(), but it's just stripped the offending character. Anyone know js and feel like fixing this?

javascript:langpair="fr|en";
  text=""+(window.getSelection?window.getSelection()
           :document.getselection?document.getSelection()
           :document.selection.createRange().text);
  if(!text)text=prompt("enter%20text%20to%20translate","");
  if(text!=null)void(window.open(
      "http://google.com/translate_t?langpair="+langpair+"&text="+text,
     "translate","scrollbars=1,resizablel=1,width=500,height=500"))

Back and Forward Links in History

Using form buttons:

<form>
<input type="button" value="Back" onclick="history.back()">
<input type="button" value="Forward" onclick="history.forward()">
<input type="button" value="Reload" onclick="location.reload()">
</form>

Using a normal link:

<a href="javascript:history.back();">Back</a>

Javascript todo-list sorter

The code below will, if put in the HEAD of a page, move all LI-items that contains a <del>-tag to the bottom of the list. Handy for TODo-lists.

        <script type="text/javascript">
                function organizeList(list) {
                      var listItems = list.getElementsByTagName("LI");
                      var len = listItems.length;
                      for (var i = 0;i<len;i++) {
                            if (listItems[i].getElementsByTagName("DEL").length > 0) {
                                list.appendChild(listItems[i]);
                                i--;
                                len--;
                            }
                      }
                  }
          window.onload = function() {
              var lists = document.getElementsByTagName("UL");
              for (var i = 0;i<lists.length;i++) {
                    organizeList(lists[i]);
              }
          }
        </script>
