Package: python3.4
Version: 3.4.2-1+deb8u3
Followup-For: Bug #931044

The following fix could be applied to the faulty Python standard library file
ultimately used by the /var/lib/dpkg/info/python3.4.postinst script:

         # Non-ASCII characters should have been eliminated earlier

Sorry to provide this patch inline, but I am using the textual bug reporting
interface! I imagine that this regression has occurred because someone has
applied the noted vulnerability countermeasure without backporting it to the
syntax understood by Python 3.5 or earlier.

I hope this helps others experiencing the same problem.
