title: Can't post Chinese characters to my search form
body: <p>I'm having a bit of trouble posting chinese characters to a search form. It works great on localhost but not on my website.</p>
  
  <p>The search input is this: 假发</p>
  
  <p>The resulting url on localhost: 
  <a href="http://search.taobao.com/search?commend=all&amp;isnew=2&amp;q=%BC%D9%B7%A2&amp;source=search1" rel="nofollow">http://search.taobao.com/search?commend=all&amp;isnew=2&amp;q=%BC%D9%B7%A2&amp;source=search1</a></p>
  
  <p>The resulting url on the website:
  StackOverflow actually encode's it,the encode result is different though, thing is that on the website instead of q=%BC%D9%B7%A2 I get q=假发 in the url itself.
  <a href="http://search.taobao.com/search?commend=all&amp;isnew=2&amp;q=%E5%81%87%E5%8F%91&amp;source=search1" rel="nofollow">http://search.taobao.com/search?commend=all&amp;isnew=2&amp;q=%E5%81%87%E5%8F%91&amp;source=search1</a></p>
  
  <p>You can see that it actually inserts the chinese characters into the query. I have no idea why this works differently on lcoahost and on a live site. The character encoding is:</p>
  
  <pre><code>&lt;meta http-equiv="Content-Type" content="text/html; charset=GB18030" /&gt;
  </code></pre>
  
  <p>But I tried UTF-8 as well, no changes.</p>
  
  <p>here's the html of my form. The search query goes to the second input box. THe first one's for transaltion, which works fine. Not sure what's the deal and whether I have to encode the characters or not and why does it work on localhost???
  Thanks in advance!</p>
