The SilverStripe custom icon font set is a collection of hand crafted and sourced icons through fontastic.me. Fontastic allows us to package together icons from multiple sources for use as a single set.
This font was created with Fontastic
You can find all icons for your SilverStripe version in this file /vendor/silverstripe/admin/client/src/font/icons-reference.html, all visible icons are installed by default.
You set the icon using private static variable $menu_icon_class and using "font-icon-iconname" ... example for icon "block-content"
private static $menu_icon_class = 'font-icon-print';
Another list of interesting SilverStripe resources are available at Storybook ... You can see this reference under Icons section.
