aall characters you use on a page,
This article was written in 2015. It might or it might not be outdated. And it could be that the layout breaks. If that’s the case please let me know.
Yesterday Peter van Grieken asked on Twitter if anybody knew a tool that displays all the different characters that are used on a page. This would be a handy tool for font subsetting: if your page only uses a few characters you don’t need to add all those other characters in your fancy font-files. Quite a few people answered to Peter’s tweet, but as far as I can tell nobody linked to a tool that does this. So I decided to create this tool.
I created a gist of the code for you to play with. Please let me know if you improved it!
