AfaIk, domain names may include special characters since a while.

ツ.gay

e: it’s real i promise

They do now! Blåhaj.world (might not work in old browsers)

Generally it’s called punycode and is encoded as xn–SOMETHING. Browsers mostly mitigate those scammer paradise tricks by rendering the punycode domain as intended only if it contains characters from a single script. Like if it contains an å, then only other characters from languages that also have å are allowed.

domain names can be basically whatever the fuck you want and it kills me how no one in sweden seems to understand this, like come on we’re supposed to be good at computers up here, we can do better than just redirecting göteborg.se to goteborg.se…
