"UnicodeDecodeError: 'ascii' codec can't decode byte " when handle unicode with WSDL call

[GoogleCodeExporter]

What steps will reproduce the problem?
1. set up a wsdl that require unicode parameters
2. the code as bleow, call the wsdl func. There are Chinese or other unicode in 
the parameters.
        client = SoapClient(wsdl=wsdl_uri, trace=True)
        response = client.XmlSubmit(identity, request, filter)

What is the expected output? What do you see instead?
I want the output of the service, but got the below information:
  File "ysta.py", line 22, in get_xml
    response = client.XmlSubmit(identity, request, filter)
  File "/usr/local/lib/python2.7/site-packages/pysimplesoap/client.py", line 140, in <lambda>

    response = self.call(method, *params)

    msg += message_body
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe9 in position 2388:

What version of the product are you using? On what operating system?
python 2.7.3 / pysimplesoap 1.0.5a/ httplib2 / CentOS 6 

Please provide any additional information below.
Trace into the lib, and got the solution.
Pysimplesoap lib get the wsdl location and action from the wsdl returned xml.  
And in unicode. So the location and headers parameters  is unicode str. When 
"msg += messgae_body" called in httplib, the message_body was attempted to 
decoded by 'ascii' codec. Then fail. 

Solution:
convert the location and action into str in clienty.py. Please advice or fix in 
the trunk.

method)

>             soap_action = str(self.action)

<             soap_action = self.action+method

Great!

Could you provide a patch and test case?

• Changed state: Accepted

The patch file is attached using hg diff with current master. Sorry about the 
test case. I cannot easily build a test case without leaking out some 
authentication information.
