Manually typing the URL does not result in 'on the fly' conversion. Copying/Pasting from the manually typed URL does not result in a conversion. Copying from the link in your comment above does result in a converted URL. So, you are correct. Notepad is not the culprit. This suggests that the browser is converting the URL before it can be copied, indicating that it converts the punycode rather than rendering it, but refreshing the page does not lead to the real site, so this only happens when copying from the address bar. I am using Cyberfox 52.0.4.
