Replying to my own post.
I got around this problem, which *looks* like a bug to me, (although I'm 
sure I don't understand the internals of xml.marshal) with this:

self.data = wddx.loads(''.join(codecs.open(self.filename,
   errors='ignore',encoding='ascii').readlines()))
where self.filename contains the numbered entity.

just in case anyone else out there is using wddx to communicate between 
python and php.
