This thread is news to me. Unicode is Unicode, no? Why restrict to Latin letters?
There is also the risk of homograph attacks. The link below is for domain name encoding via IDN, but the same applies to usernames. You could easily impersonate another user by having chars that look similar.

Because URLs are usually in ASCII. That was a standard. Check RFC 1738 and 3986. Now, you can use percent encoding, but why use that. It just complicates things.
There is a standard way to encode Unicode into URLs, it definitely doesn't have to be ascii. Percent encoding is used all over the place.
EDIT: I don't mind a down vote but double down voting me from your alt @Asudox@lemmy.world is not cool. That's sockpuppetry/vote manipulation.
