I agree with your comment below mentioning Cyberfox -- the browser appears to be to blame, not Windows per se. The only question is why your browser is doing that. On both Firefox and Chrome, I am not getting the Unicode inserted into my clipboard, only the actual punycode. In fact, if I attempt to copy the Unicode from the address bar in either browser, it pastes as https://www.xn--e1awd7f.com/ https://www.xn--e1awd7f.com/ in the text editor, not as "epic.com." Edge seems to be completely immune to this exploit; it renders the punycode as punycode in the URL (I suppose it just doesn't "understand" punycode is all.)
