title: Grunt does not compile font-awesome.LESS or CSS
body: <p>The already answered questions on this issue didn't solve my problem. </p>
  
  <p>When I pull in the <a href="http://fortawesome.github.io/Font-Awesome/" rel="nofollow noreferrer">Font Awesome</a> library with <a href="http://bower.io/" rel="nofollow noreferrer">Bower</a> and integrate the library directly in <code>index.html</code> or alternatively use the hosted version like in the following, the icons are displaying fine:</p>
  
  <pre><code>&lt;link href="bower_components/fontawesome/css/font-awesome.css" rel="stylesheet" /&gt;
  
  or
  
  &lt;link href="//netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.css" rel="stylesheet"&gt;
  </code></pre>
  
  <p>However, no icons are displayed when I am compiling font-awesome.less or font-awesome.css with <a href="http://gruntjs.com/" rel="nofollow noreferrer">Grunt</a> (Please see the picture: The Bootstrap LESS which I import in base.less works fine!):</p>
  
  <p><strong>frontend.less:</strong></p>
  
  <pre><code>@import "base.less";
  @import "/bower_components/fontawesome/less/font-awesome.less";
  
  //@import (less)"//netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.css";
  </code></pre>
  
  <p><strong>Gruntfile.js (excerpt):</strong></p>
  
  <pre><code>less: {
          development: {
              options: {
                compress: true,  // Minification
              },
              files: {
                // Compile frontend.less into frontend.css
                "./public/assets/css/frontend.min.css":"./app/assets/less/frontend.less",
                // Compile backend.less into backend.css
                "./public/assets/css/backend.min.css":"./app/assets/less/backend.less",
              }
          }
      }, 
  </code></pre>
  
  <p>I would appreciate your advise how to import / compile <code>font-awesome.less</code> correctly with Grunt or if this is a Font Awesome bug.</p>
