I built this proof of concept of a tool called https://text.makeup. It is meant to be a friendly Unicode explainer – meant not just for Unicode nerds, but nerds of any kind. Useful for debugging, but also learning.
You can go there now to play (much more fun on desktop!), but I also recorded a 5-minute video that explains it further.
I am curious: Does this feel like fun? Is it worth building out for real? What would you like to see in it if so?
