Colons are special characters in URIs, so if you wanted to specify
a hostname containing a colon, you would have to use an escape like
http://foo%3A80/.

Many currently deployed browsers undo %hex encoding at the wrong level
of parsing, and would (incorrectly) treat http://foo%3A80/ just like
http://foo:80/.
