Review comment:
Maybe we should do `error="replace"` or something so a log written in
another encoding can still be partially read. I’m suspecting this input-output
encoding mismatch only happens on Python 3.7+, when Python starts automatically
coerce the default legacy C to UTC-8 ([PEP
538](https://www.python.org/dev/peps/pep-0538/)). If this is the cause, setting
`utf-8` here is a correct move, but we should still provide a fallback for
weird platforms that need/want to use a platform-specific encoding. Perhaps a
new config to explicitly set what encoding to use here?
