title: How to use folium.icon with fontawesome
body: <p>I am looking to use a custom fontawesome icon, thx.</p>
  
  <p>I would like to change the icon from folium.icon using fontawesome icons.</p>
  
  <p>For example, I want to change this:</p>
  
  <pre class="lang-py prettyprint-override"><code>    import folium
  
      m = folium.Map(location=(25.0431, 121.539723), zoom_start=12,tiles='Cartodb Positron')
  
      folium.Marker(
          location=[25.0431, 121.539723], 
          icon=folium.Icon(color="red",icon="fa-truck", prefix='fa')).add_to(m)
  
      m
  </code></pre>
  
  <p>To a <a href="https://fontawesome.com/icons?d=gallery&amp;q=hamburger" rel="noreferrer">burger icon from fontawesome</a> as shown below:</p>
  
  <pre class="lang-py prettyprint-override"><code>    folium.Marker(
          location=[25.0431, 121.539723], 
          icon=folium.Icon(color="red",icon="fa-hamburger", prefix='fa')).add_to(m)
  </code></pre>
  
  <p>But it does not work for me!</p>
  
  <p>Many thanks!!!!</p>
