title: font awesome shows weird characters (not squares)
body: <p>sometimes font awesome shows weird characters when you hit the page. Refreshing the page is one fix but sometimes it is not. You need to hard refresh to fix it. <br>
  I checked from developer console and I didn't see any errors. When I check the page css and fonts are loading correctly.</p>
  
  <p>I'm using font awesome like this:</p>
  
  <pre><code>&lt;i class="fa fa-hourglass-start fa-2x"&gt;&lt;/i&gt;
  or
  &lt;i class="fa fa-eye fa-2x"&gt;&lt;/i&gt;
  or
  &lt;i class="fa fa-ban"&gt;&lt;/i&gt;
  </code></pre>
  
  <p>Here is how it looks like.
