in reply to CGI::Application - Which is the proper way of handling and outputting utf8

CGI works with STDIN and STDOUT, so that is easy:

binmode STDIN, ":encoding(utf8)"; binmode STDOUT, ":encoding(utf8)";
However, $ENV{QUERY_STRING} might also need this treatment, but environment variables can't. This means you have to hack around it a little:
my $cgi = $ENV{REQUEST_METHOD} eq 'GET' ? CGI->new(decode_utf8 $ENV{QUERY_STRING}) : CGI->new;

(all code untested)

Juerd # { site => 'juerd.nl', do_not_use => 'spamtrap', perl6_server => 'feather' }

    I don't think this will work because QUERY_STRING is %-encoded. If C::A does not perform character decoding itself, you'll have to post-process each parameter that C::A creates with the appropirate decode (e.g. decode_utf8).

      Good catch. Indeed passing a utf8_decoded query string to CGI->new makes no sense, and you need to decode each thing individually. Time for an encoding aware CGI.pm!

    Maybe better :raw:encoding(utf8)

      Why?
