srsly tho interesting stuff, I wonder if I should be running a library like this on my usernames? I could imagine that there's an avenue for error if someone uses a weird character but then when you try and access the subdomain it gets changed https://www.npmjs.com/package/idna-uts46

yeah I think some reddit mod just typed out some enormous regexes for their automod config

Yeah also it came to my attention that all these Unicode characters aren’t even allowed in handles cause they’re ascii 😅 So you can probs do something way simpler. Just wanna take into account letter substitutions like l/1 for i, etc

i generally prefer to run a pass over a string to fold characters into what they could look like as letters. like f00 -> foo and then your regex only has to match /foo/ rather than /f[o0][o0]/

It might just be me being a grumpy weirdo (extremely possible) but I get tired of people asking me if they can use things which I already explicitly designated as freely usable. I do like a heads-up though ("hey I'm using [thing] for [project], ty") obviously I can't speak for dholms though

(not saying this to have a go at your or anything, it's just a weird little pet peeve of mine and I went off on a bit of a tangent heh)

ah fair enough, I think the only reason I really said anything is that he liked the post like 2 seconds earlier so I was being pseudo-conversational
