What Catalyst does with UTF8 in your GET and classic HTML Form POST

=head2 UTF8 in URL query and keywords

The same rules that we find in URL paths also cover URL query parts.  That is
if one types a URL like this into the browser

    http://localhost/example?♥=♥♥

When this goes 'over the wire' to your application server its going to be as
percent encoded bytes:


    http://localhost/example?%E2%99%A5=%E2%99%A5%E2%99%A5

When L<Catalyst> encounters this we decode the percent encoding and the utf8
so that we can properly display this information (such as in the debugging
logs or in a response.)
