title: Google Fonts: Language selection not working
body: <p>I am using the Google Font <a href="https://fonts.google.com/specimen/Roboto" rel="nofollow noreferrer">Roboto</a> on quite a few client websites.</p>
  
  <p>When you are customising the font on Google Fonts you have many language options to pick from:</p>
  
  <ul>
  <li>Greek (Supported by Roboto)</li>
  <li>Latin Extended (Supported by Roboto)</li>
  <li>Cyrillic (Supported by Roboto)</li>
  <li>Vietnamese (Supported by Roboto)</li>
  <li>Cyrillic Extended (Supported by Roboto)</li>
  <li>Greek Extended (Supported by Roboto)</li>
  <li>Latin (Supported by all Fonts)</li>
  </ul>
  
  <p>For these client sites, I only need to use the Latin language, and don't need to load in any other languages.</p>
  
  <p>However, when I load this font in and the Latin language defined, you can see all the other languages are also loaded in the generated stylesheet:</p>
  
  <p><a href="https://fonts.googleapis.com/css?family=Roboto:300&amp;subset=latin" rel="nofollow noreferrer">https://fonts.googleapis.com/css?family=Roboto:300&amp;subset=latin</a></p>

  <p>It was my understanding that defining <code>&amp;subset=latin</code> loads in only that language, so why are all the languages being loaded in here?</p>
