1. Control Panel

3. In the Virtual Host field, type in 来锐.com

Error: Please enter a valid virtual host.

Even though 来锐.com is a perfectly valid domain. As a matter of fact, we own this domain.

After doing some research, here's some things to note

• Unicode DN are canonized to an ASCII/punycode DN.
• Although users can't enter their host as 来锐.com, they can enter the canonized name, xn--vrvo03h.com, as their host.
• When validating DN, there may be some places where we should be validating for Unicode DN and in some places we need to be validating for ASCII DN
• Most browsers will convert Unicode DN to a punycode DN because of phishing issues. Firefox, Safari and Opera will display the Unicode if it's in your browser's whitelist. For Firefox, .cn domains are in the whitelist, so you many want to test with 来锐.cn instead of 来锐.com
