title: Ruby 1.9 invalid multibyte char (UTF-8)
body: <p>I've searched all over and tried everything but I still get:</p>
  
  <pre><code>invalid multibyte char (UTF-8)
  </code></pre>
  
  <p>When doing something like:</p>
  
  <pre><code>some_string.gsub(/…/)
  </code></pre>
  
  <p>Even though I added this to the top of the file:</p>
  
  <pre><code># encoding: utf-8
  </code></pre>
  
  <p>Any help?</p>
