Japanese characters are sent as numeric character references

What steps will reproduce the problem?
1. As a parameter of a SOAP Binding object, enter Japanese characters, e.g. 
"しん￥"
2. Enable XML logging
3. Send the SOAP request
4. Verify OutputBody in console

What is the expected output?
I expected it to be UTF-8 encoded by default, so "しん￥" should have been 
displayed and sent.

What do you see instead?
"しん￥" is converted to numeric character references, e.g. 
"&#x3057;&#x3093;&#xFFE5;"

What version of the product are you using? On what operating system?
wsdl2objc 0.7, OS X 10.9.2 and 10.8.5

Please provide any additional information below.
Maybe the call to "xmlDocDumpFormatMemory" is the culprit here.
If I call "xmlDocDumpFormatMemoryEnc" instead, while passing "utf-8" as the 
encoding, the expected value is displayed and sent to the SOAP server.
