Let's do a case-insensitive comparison and add a test for LocalHost.

I guess punycode encoding should not happen here.  This seems correct.

Is this the UTF-8 encoding if an uppercase non-ASCII character?  Careful when committing, because sometimes our tools like webkit-patch UTF-8 encode non-ASCII characters.  svn  commit doesn't change the characters.
We should probably include a test with an uppercase non-ASCII character and a test with a lowercase non-ASCII character just for fun.

And let's add a test with a.b.subdomain.Example.com
