title: Why font awesome icon \f105 is not appears?
body: <p>I am using a breadcrumb BS4 like this (fa latest version)</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.breadcrumb &gt; li + li:before {
    font-family: 'FontAwesome';
    content: '\f105';
    padding: 0 10px;
    color: rgba(255, 255, 255, 0.7);
    font-weight: normal;
  }</code></pre>
  </div>
  </div>
  </p>
