Python3 Django ZipFile HttpResponse UnicodeDecodeError

I created a zip file like so:

        zipped_file = zipfile.ZipFile("csvOutput{}.zip".format(timestamp), 'w')
        zipped_file.write(sms_file_path)
        zipped_file.write(mail_maga_file_path)
        zipped_file.close()

And want to send it, which I am currently using this code:

        response_file = open('csvOutput{}.zip'.format(timestamp))
        response = HttpResponse(response_file, content_type="application/force-download")
        response['Content-Disposition'] = 'attachment; filename=csvOutput{}.zip"'.format(timestamp)
        return response
        raise Http404

But maybe something I am using is out of date? Python keeps crashing with a byte it can't decode in unicode:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0x94 in position 14: invalid start byte

Says line 100 is throwing the error, which would be the line with HttpResponse()

Edit: I've changed the content_type to application/zip and am getting a new error (that seems better?):

caution:  zipfile comment truncated
error [output.zip]:  missing 3232109644 bytes in zipfile
  (attempting to process anyway)
error [output.zip]:  attempt to seek before beginning of zipfile
  (please check that you have transferred or created the zipfile in the
  appropriate BINARY mode and that you have compiled UnZip properly)

I've managed to fix the issue, by opening the file with 'rb' as in:

response_file = open('csvOutput{}.zip'.format(timestamp), 'rb')

Looks like this issue is with your time stamp string.

response_file = open('csvOutput{}.zip'.format(str(timestamp).encode('utf-8').strip()))

or

response_file = open('csvOutput{}.zip'.format(str(timestamp).encode('ISO-8859-1').strip()))
