Pardon my ignorance, but what is "utilities.urw"??

Means what? Does what?
Does the problem still happen without that?
Funny, the indentation changed there --- for the very last time, is
that the actual code of a standalone script that reproduces the
problem?

Looks like the file is stuffed. Have you tried inspecting it with a
tool that would actually show a '\x00' or a '\xff' unambiguously? If
you don't have a fancy one, use the Python interactive prompt:
open('your_file.csv', 'rb').read()

Just make sure it's runnable and it's what you actually ran thanks.
