here’s also a perl-script that does it
------------------------------------------
use Encode qw(decode encode);
use LWP::UserAgent;
my $str = '深入 so what';
my $oct = encode("gb2312", $str);
my $url = 'http://wbc-inco.net/object/event/past';
my $ua = LWP::UserAgent->new();
my $response = $ua->post( $url, { $oct => $oct } );
my $content = $response->decoded_content();
