ValidationFailure on real domains with accent characters

[serain]

I have a know legit domain that contains the German accent ä. This domain is registered, public whois record etc.

Running it through validators.domain(target) returns a ValidationError.

Apparently such domains are valid since 2003: https://www.iis.se/english/domains/se/idn/

PRs welcome!

I'll give it a try, time to play regex gold I guess. I noticed it also trips up on valid Chinese domain names. In Latin charsets these are basically domain names and TLDs that start with xn--.

Domains like аренда.орг and मुम्बई.संगठन are valid. (disclaimer, i have not looked up the translations of these words, they might be something horrible :))

Here you'll find some more nice tld's: https://namestat.org/xn--i1b6b1a6a2e
