Custom Icons

Hi I found a thread here about adding custom icons:

http://blueowlcreative.com/support_wp/forums/topic/svg-icon-upload/

I added my own icons to the path fortuna/stylesheets/fonts and I added the css to the icons.css in the same location. I see that you mention setting up a class like this one: \fortuna\includes\shortcodes\vc\boc_iconpicker.php
How do I know what name to use for the icon? would this work with the type of set up that I am doing?
We are launching this site very soon so your prompt response is highly appreciated!!
Thanks
