This is causing a lot of grief for international customers.

    So I used the code from the above link and added a function to the end of it.

    def safe_urlencode(query, **kwargs):
        safe_query = dict()
        for key, value in query.iteritems():
            safe_query[key] = unicode_to_ascii(value)
        return urlencode(safe_query, **kwargs)

    Then for the customer data I did: safe_urlencode(trans['custBillData'])

    using string.encode('latin-1') seems to fix the problem. I need to research to see if there is already a generic way to apply this to all strings sent to urlencode.

    Okay, I've changed the import in payment.modules.authorizenet.processor from urllib.urlencode() to django.utils.http.urlencode(), rebuilt Satchmo & done some testing resubmitting the problematic data to auth.net. Looks like Django's urlencode() does the trick, by adding in the step of calling Django's smart_str() func on each of the key/value pairs before passing off to urllib.urlencode() to ensure all data is Unicode before url-encoding.

    Sadly, I am still on SVN only right now & don't have a separate environment setup for the new hg based Satchmo. I'm a bit wary that a patch may somehow be off, but I'm going to attach one anyway so you guys can apply it, test it, and hopefully we can get this committed & no longer have this issue.

    Thanks, guys.
