PowerQuery should recognise international (Unicode) web addresses
This website uses an accented character:
I can use the old Get Data from Web Legacy Wizard providing I add the Magyar language pack to Windows . Powerquery returns "Bad request" unless I translate the address to Punycode
Allow the end-user to enter their web site address as they know it without having to translate it into American. Sure, doing it in code is no problem, and I'd use VBA, but this is for users who don't know code.

Just checked it, in my Excel (I'm on Insider Fast currently, English UK locale) Power Query automatically translates international domain names with Punycode. In particular your URL is transformed as https://www.xn--kalriaguru-ibb.hu/ and connected successfully.
