I ran into this problem today when writing python data structures into a
database. Only ASCII is safe in this situation. I understood the
Python docs that protocol 0 was ASCII-only.
I use pickle+base64 now, however, this makes debugging more difficult.
Anyway, I think that the docs should clearly say that protocol 8 is not
ASCII-only because this is important in the Python world. For example,
I saw this issue because Django makes an implicit unicode() conversion
with my input which fails with non-ASCII.
