Hi All,
POSTing UTF-8 data returns "Internal Server Error: Wide Character in syswrite". Example:
use WWW::Mechanize;
use encoding 'utf-8';
binmode STDOUT, ':utf8';
....
$mech->submit_form(form_name => 'form');

I get the "Wide Character" error if $mech->content contains UTF-8 data ... It works if the data is ASCII. What am I missing?
Thanks!


Update:
I tried installing libwww-perl-5.8.26 - got a new error "HTTP::Message content must be bytes"
Solution was to edit HTTP/Request/Common.pm, adding utf8 lines 
        $k =~ s/([\\\"])/\\$1/g;  # escape quotes and backslashes
        if (utf8::is_utf8($v)){
            utf8::encode($v);
        }
        push(@parts,
         qq(Content-Disposition: form-data; name="$k"$CRLF$CRLF$v));<<

And removing the "use encoding 'utf-8';" line from the sample script.
Working code: 
use WWW::Mechanize;
binmode STDOUT, ':utf8';  # Removes 'wide character' warnings
$url = "http://localhost/test.cgi";
$mech = WWW::Mechanize->new();
$mech->get($url);
if ($mech->success) {
  if ($mech->form_name( 'frmLookup' )) {
        $mech->submit_form(form_name => 'frmLookup');
      print "Success";
    }
}

Example form: 
print qq{Status: 200
Content-Type: text/html

<html>
<head>
  <meta http-equiv="content-type" content="text/html; charset=UTF-8">
</head>
<body>
  <FORM NAME="frmLookup" ACTION="test.cgi" METHOD="Post" ENCTYPE="mult
+ipart/form-data">
    <INPUT TYPE="text" NAME="test" VALUE="刘">
  </FORM>
</body>
</html>};

Note: this works for multipart/form-data encoding. A similar edit is required for x-www-form-urlencoded encoding.
