Ens domain name invalid bug need some help

I really need some have with a bugged out domain name and I don’t know what I can do because I’m not very good at this type of stuff, I just bought a domain name called ßullish.eth, and is invalid and I know it the ß that messing everything up and now I cant list it on opensea or anything. Is there anything I can do to change it or somehow verify it and or change it somehow, I know it’s a big ask but it’s really affecting me and it sucks.

Note that you didn’t buy an actual domain name; you bought a decentralized name for your wallet. It can’t be used like a regular domain name on the internet.

As far as your question goes, no, I don’t think you can actually revert a purchase made this way. I’m however very unfamiliar with this system, and therefore also don’t know how expensive these names are? With regular domain names, its’ usually the easiest to just buy the correct domain name as well.

how do i buy the actual domain name
