IDN Display Test
This page is used as part of the SANS SEC522 "Defending Web Application Security Essentialls" class to demonstrate how different browsers display international domain names.
Safari will render the URLs with international characters. Chrome will show punycode in the URL bar instead. Firefox will show the international domain name but briefly display the punycode form as the page is being built. More about this: https://isc.sans.edu/forums/diary/This+Article+is+Brought+to+You+By+the+Letter+12494/20319/.
Also note that the page uses a valid TLS certificate.
