I do have a tendency to check where the link leads before clicking on it, so the difference between those two is quite obvious to me: http://example.com/ vs http://xn--exmple-4nf.com/, but a lot of people probably do not do that.

I would definitely not click on the second one.

On my Fedora system (KDE) I have unified all unused and pointless folders (Documents, Pictures, Public, Templates) into a single folder called Unspecified with a trash icon. You could probably do that as well.
