title: phantomjs font rendering issue
body: <p>Using phantomjs v1.9.7, the latest version, there's a problem rendering some characters on my production server. No problems on dev server. </p>
  
  <p>In rendering the phantomjs.org homepage, the fonts with "strong" tag or some kind of bold font like "700em" render correctly, but normal font-weight aren't.</p>
  
  <p>I haven't noticed this problem with any other urls yet.  </p>
  
  <p>Also all Chinese characters from any url (that I've checked so far) render with boxes on the production server, but correctly on the dev server.</p>
  
  <p>I have no idea what the problem is.</p>
  
  <p>Here's a screenshot of a section of <a href="http://phantomjs.org" rel="nofollow noreferrer">http://phantomjs.org</a> for each server:</p>
