title: Rails 3 force localization language for specific text
body: <p>Any way to force the translation to a specific language only for some text. Something like:</p>
  
  <pre><code>t("my.text",:fr)
  </code></pre>
  
  <p>The reason is that i want the user to be able to change the language of their content but not the site interface. Thanks!</p>
