I don't understand. You should use quote_plus() before setting
the cookie, and unquote_plus() after retrieving the cookie.

Steps:
(1) You have a pickled object.
(2) You use quote_plus() to transform the pickled object's
    string to another string.
(3) You set the cookie with RESPONSE.setCookie()
(4) You can now retrieve the cookie by using
    REQUEST.cookies['myCookieName']
(5) You unpickle the object.

If your steps are different from the above, then I don't know
what you are doing. :)

A '\012' in the pickled object's string will be mapped
to '%0a', which is perfectly fine to be stored as a cookie.

Perhaps your problem is that you are not reading/writing your
pickled file by using the binary tag as in 'rb' or 'wb'.

    myFile = open('myFileName', 'rb')
    myPickledString = myFile.read()
    myFile.close()

    ....

    myFile = open('myFileName', 'wb')
    myPickledString = urllib.unquote_plus(
                      REQUEST.cookies['myCookieName'])
    myFile.write(myPickledString)
    myFile.close()

Anyway, please outline your steps so I can take a look
at why it isn't working for you.
