LoginInfo Icons don't load

LoginInfo Icons don't load



I have a styleguide eSpace that works fine (done with a external team).

Now I'm trying to create an Application using the same design. I've copied the LoginInfo webblock to my espace but the standard icons (don't appear) 

Looking at the CSS, I've identified that the link as the style "Login_Info_Username" 

SyntaxEditor Code Snippet

.Login_Info_Username:before {
    content: "\f007"; /* fa-user at http://fortawesome.github.io/Font-Awesome/icons/ */

Anyone have any clue about what I'm doing wrong?

The LoginInfo is an example, none of the "default" icons have the same problem.
