Funny this.. and I found the above website when looking at a concern I had regarding UTF-8 DNS, and phishing attacks.
It occurred to me that UTF-8 control codes, or other non-ASCII letters could be embedded in a domain, giving a domain which is representable in emails (such as a "paypal.com" link), which look 100% legitimate - but infact use different UTF-8 characters to direct to a fake website.
