'utf-8' codec can't decode byte / invalid start byte

[slspencer]

We're encountering a compiler Warning message just after downloading libapprun_hooks-Release-x86_64.so.
The message says there's an invalid start byte in pygettext3.

This problem may be related to how Python 3 handles these types of errors, whereas previously Python 2 just sort of accepted them:
