SOAP ERROR - Encoding

Hi guys, I created a simple wsdl web service. Everything works fine, but when I fill the fields with accents and send the soap request, the PHP returns me an error: Fatal error: Uncaught SoapFault exception: [Client] SOAP-ERROR: Encoding: string 'ol\xe1...' is not a valid utf-8 string in PATH\cilent.php 16 Stack trace: #0 [internal function]: SoapClient->__call('Send', Array) #1 PATH\cilent.php(16): SoapClient->Send(Array) #2 {main} thrown in PATH\cilent.php on line 16 I tested this same request using the eclipse web service explorer(It's a java client web service inside the eclipse IDE) and the response was ok. I found few topics about this issue on the google. One related solution to this problem is use the utf8_encode() function. I tried add this function before to send the soap request but didnt worked. I think that this problem is in the PHP soap client because using the eclipse web service explorer it works fine. Here is my php soap client: $client = new SoapClient('http://app/webservice.wsdl'); $return = $client->Send(array('token' => '123123', 'message' => array( 'text' => 'This is a string with special characters á é í ó ú', 'dest' => 'John', 'sender' => 'Augusto'))); As I said I tried to use the utf8_encode() here: $return = $client->Send(array('token' => '123123', 'message' => array( 'text' => utf8_encode('This is a string with special characters á é í ó ú'), 'dest' => 'John', 'sender' => 'Augusto'))); But the problem still. I tried also add the propertie defencoding in the soap server: $server->soap_defencoding = 'UTF-8'; But still not working. What I'm missing? Thanks Augusto Morais
