Xenforo bug 1.4.5

I am trying to assign some of the new 4.3 icons to my forum nodes. Here is the forum link: enter the link here

The problem I ran into is that the old icons display very well, but the new icons display as a square white box. Here is some existing working code followed by new icon code that doesn't work.

Work Icon:

/* General Chat */
.node_9 .forumNodeInfo .nodeIcon:before {content: '\f1d7' !important;}

      

        
        
        
      

    

Icon not working:

/* Requests */
.node_112 .forumNodeInfo .nodeIcon:before {content: '\f234' !important;}

      

        
        
        
      

    

I have no idea how to fix this. Any help would be appreciated.

I read this:

EASY: default CSS

Use this method to get the default Awesome standard font.

Copy the entire project containing the font into your project. in your html, provide the location in your font-awesome.min.css. Check out the examples to get started using font Awesome!

I don't understand what it is asking me how to do, since all my settings are in extra.css. I don't have a RAW html site that uses
