Here's an example of a url that will trigger the "Nothing Submitted" error on Submit step 1 even if something is submitted:

http://www.asahi.com/english/TKY201003170253.html

On closer inspection...

Array ( [submit_editorial] => [submit_orig_url] => http://www.asahi.com/english/TKY201003170253.html [submit_title] => asahi.com��ī��ʹ�ҡˡ�Internet posts held to libel standards - English )

The title is (if Assembla can show the Japanese characters):
asahi.com（朝日新聞社）：Internet posts held to libel standards - English

When Submit tries to save the serialized array to the database in /submit/libs/SubmitFunctions.php line 264~, it gets cut oof when the characters begin:

a:3:{s:16:"submit_editorial";b:0;s:15:"submit_orig_url";s:49:"http://www.asahi.com/english/TKY201003170253.html";s:12:"submit_title";s:73:"asahi.com

Therefore, Hotaru is unable to unserialize it properly and the url is considered "false", hence "Nothing Submitted".

            //you need iconv to encode to utf-8
            if (function_exists("iconv"))
            {
                if (strcasecmp($encoding, 'utf-8') != 0) {
                    //convert the html code into utf-8 whatever encoding it is using
                    $string=iconv($encoding, 'UTF-8//IGNORE', $string);
                }
            }

if(!function_exists("iconv"))
{
    function iconv($from, $to, $string)
    {
        $converted = htmlentities($string, ENT_NOQUOTES, $from); $converted = html_entity_decode($converted, ENT_NOQUOTES, $to); return $converted;
    }
}
