Description

When sending a XMLRPC request thru a XmlRpcClient object, calls to :

XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
config.setEncoding("ISO-8859-1");
XmlRpcClient client = new XmlRpcClient();
client.setConfig(config);

will only set the request's encoding but not the response.
Therefore, response's parser will use the default UTF-8 encoding which only compatible with the US-ASCII character set (first 128 chars).

If the response is encoded using ISO-8859-1 (or other US-ASCII extensions) and contains special characters like the euro symbol (€), the following exception is thrown by the SAX parser (complete stack trace) and the response cannot be processed :
