In general though, Python 3 works very badly with LANG=C. Upstream
Python recommends just not using LANG=C at all, and instead using a
UTF8 locale, like C.UTF-8 instead.

In fact, starting with 3.7, Python will emit a big warning when it is
run on a non-UTF8 locale, and try to fallback to C.UTF-8 if it can.

There might be something to fix in this case (I haven't had time to
look at it yet), but I'd still advise you try and use a UTF8 locale
when running Python scripts in the future, if at all possible.
