string - Decoding double encoded utf8 in Python

I've got a problem with strings that I get from one of my clients over xmlrpc. He sends me utf8 strings that are encoded twice :( so when I get them in python I have an unicode object that has to be decoded one more time, but obviously python doesn't allow that. I've noticed my client however I need to do quick workaround for now before he fixes it.

Raw string from tcp dump:

<string>Rafaxc3x85xc2x82</string>

this is converted into:

u'Rafaxc5x82'

The best we get is:

eval(repr(u'Rafaxc5x82')[1:]).decode("utf8") 

This results in correct string which is:

u'Rafau0142' 

this works however is ugly as hell and cannot be used in production code. If anyone knows how to fix this problem in more suitable way please write. Thanks, Chris

>>> s = u'Rafaxc5x82'
>>> s.encode('raw_unicode_escape').decode('utf-8')
u'Rafau0142'
>>>
