Manifesto

I kind of love Unicode. There are so many stories hidden within all the codepoints, and so much strange complexity.

I want this tool to be somewhere at the intersection of “useful” and “fun.” You might want to just paste a string that’s giving you trouble, but not just that. Hopefully, you will also want to click around, learn, explore. I want information, but I also want stories.

This is meant to be a site for nerds, but specifically not Unicode nerds. (Many sites for Unicode nerds, filled with technical info and jargon already exist!)

Proof of concept

This site is a proof of concept. Only some aspects and some specific examples work (more information about coverage).

Do you think it could be useful for you or others? What would you want to see? Debugging horror stories? Escaping? Regional stuff? RegExps? Python? RTL? Should it be open sourced? More performant? Better designed? Please send encouragement and bug reports if you’d like it become a real thing!
