title: Rails 3 UTF-8 query string showing up in URL?
body: <p>I have a search query form on my home page (/)</p>
  
  <pre><code>&lt;% form_tag(search_path, :method =&gt; :get) do %&gt;
    &lt;%= text_field_tag 'query' %&gt;
    &lt;%= submit_tag "Search", :name =&gt; nil%&gt;
  
  &lt;% end %&gt;
  </code></pre>
  
  <p>When I submit this search form, I want to end up at (/search?query=foo). However, right now I get /search?utf8=%E2%9C%93&amp;query=foo. What's that utf8 parameter doing there? How can I get rid of it?</p>
  
  <p>Thanks.</p>
