OK, I erroneously understood that the failure mode was that mojibake was
produced.

OK, I now tried it myself and indeed it produces the following error:
UnicodeEncodeError: 'ascii' codec can't encode character '\xfe' in position
0: ordinal not in range(128)
My suggestion would be to make this error message more specific.
In particular, if we have LC_TYPE/LANG=C or unset,
we could print something like the following information
(on Linux only):
"""
You are attempting to use non-ASCII Unicode characters while your system
has been configured (possibly erroneously) to operate in the legacy "C"
locale,
which is pure ASCII.
It is strongly recommended that you configure your system to allow
arbitrary non-ASCII
Unicode characters This can be done by configuring a UTF-8 locale, for
example:
export LANG=en_US.UTF-8
Use:
locale -a | grep UTF-8
to get a list of all valid UTF-8 locales on your system.
