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.
I can unzip it in Windows XP. The file within it (called "data") is XML
encoded as UTF-16LE (2 bytes per character, low byte first), but without
the initial byte order mark. Python's zipfile module says "BadZipfile:
File is not a zip file".
If I strip off all but the last 4 zero-bytes then the zipfile module can
open it:
decoded = base64.b64decode(datum)
five_zeros = chr(0) * 5
while decoded.endswith(five_zeros):
decoded = decoded[ : -1]
f = open('data.zip', 'wb')
f.write(decoded)
f.close()
x = zipfile.ZipFile('data.zip', 'r')
