Fixed in CVS HEAD.

By default ext/soap espect all string data in utf-8 encoding.

Now it is possible to change internal encoding with "encoding" option. It is acceptable both by SoapClient and SoapServer.

$SOAP = new SoapServer("test.wsdl", 
  array('encoding'=>'ISO-8859-1');

I will check it out.. sounds great!

Hi, I tested the "encoding" option, but it doesn't work yet. In my case, I need to send/receive chinese characters in the data. So firstly I hope the SOAP data can encode with "gb2312":
$SOAP = new SoapServer("test.wsdl",array('encoding'=>'gb2312'));

Unfortunately, the return data is like below and "encoding" option is still 'UTF-8':

What's the problem?

I've checked with the current version (5.0.1) and it's working fine both in SoapClient and SoapServer.

The problem that remains is with SoapFault. It seems it's not recognizing the enconding given before to the Server or Client Class. Here is an example:

function AlteraEstado($dados) {
	if ($dados == 'GARBAGE') return new SoapFault("Server", "?edilha");
	else return array("Answer"=>"OK");
}
$server = new SoapServer("GPR.wsdl", array('encoding'=>'ISO-8859-1'));
$server->addFunction(array("AlteraEstado"));
$server->handle();

This code returns no valid XML Soap Envelope back to client (I suppose it breaks...).

server:
<?php
        function FindZipInfo($zipCode)
        {
                /*if($zipCode == 100021)
                        $str = "Beijing";
                else
                        $str = "????";
                return $str;*/
                return $zipCode;
        }

        header("charset='GB2312'");
        $server = new SoapServer("http://192.168.128.22/soap/test.wsdl", array('encoding'=>'GB2312'));
        $server->addFunction("FindZipInfo");
        $server->handle();
?>
client:<?php
        try
        {
                header("charset='GB2312'");
                $client = new SoapClient("http://192.168.128.22/soap/test.wsdl", array('encoding'=>'GB2312', 'trace' => 1));
                $result = $client->FindZipInfo("&Ouml;&ETH;&Icirc;&Auml;&frac14;??&Ntilde;??&frac14;??&Ntilde;??&frac14;??&Ntilde;??test&frac14;??&Ntilde;??&raquo;??&cedil;&iuml;&acute;&icirc;&Aacute;??");
                //echo $client->__getLastRequest();
                echo $client->__getLastResponse();
                //echo $result;
        }
        catch(SoapFault $fault)
        {
                echo "SOAP Fault: (faultcode: {$fault->faultcode}, faultstring: {$fault->faultstring})";
        }
?>

~my question: why:
