Display image with css content

Question

I have to work on a symphony project written by others. I've investigated why some icons, like facebook icon or shopping cart icon won't display on IExplorer, when I found something I dont understand: The html and css below outputs a facebook icon and I don't know how?

HTML:

<i class="facebook-icon"></i>`

CSS:

.facebook-icon::before{
  content:"\e905";
}

What does this mean, how does this work?

Maybe its just doesn't really support IE. did you try it in other browsers? — Vincent Dapiton

Questions seeking code help must include the shortest code necessary to reproduce it in the question itself preferably in a Stack Snippet. See How to create a Minimal, Complete, and Verifiable example — Paulie_D

Its because of the font file that is attached to it.. the content by itself is useless. — Jones Joseph

That is probably a unicode character. Look at this post: stackoverflow.com/questions/3027448/…. You might have to specify a unicode font for IE like font-family: Lucida Sans Unicode, Arial Unicode MS, Arial; — Cave Johnson

They are using a custom font in which the character \e905 is just a facebook icon
