I have made a slight change so that it saves css vars to your stylesheet.
You can use these in scss or css for :after / :before pseudo classes to dynamically set the content.
I did this because i myself had the problem that my webfont would expand all the time and i couldn't use the codepoints provided, because they would change when i added icons.
i know this probably isn't the most perfect solution for the problem. it would probably be better if it would have an option and generate a scss variable file or just straight up use the same codepoints that have already been processed (i thought that was how the .fontcache.json file worked in the first place)
