Here's a sample with some dummy data from the web service:
http://webcomm.webfactional.com/htdocs/data.zip

That's the zip created in this line of my code...
f = open('data.zip', 'wb')

If I open the file it contains as unicode in my text editor (EditPlus)
on Windows XP, there is ostensibly nothing wrong with it.  It looks
like valid XML.  But if I return it to my browser with python+django,
there are bad characters every other character

If I unzip it like this...
popen("unzip data.zip")
...then the bad characters are 'FFFD' characters as described and
pictured here...

If I unzip it like this...
getzip('data.zip', ignoreable=30000)
...using Scott's function at...

...then the bad characters are \x00 characters.
