One of my tox-using projects broke because of this, and I took it as a
useful piece of knowledge, exactly like you suggest here.

BTW everyone: let's not focus solely on LANG for locale information.
LC_CTYPE and LC_ALL are also important (and override LANG, if they're
set).

Ideally any examples that pass through LANG ought to pass through LC_*
as well.  I'd submit a pull request for the tox docs linked in the quote
above if I weren't feeling tired after a long day (don't ask).

This is, or so I'm told, a classic book. I can see why. It is long and it
requires a great effort to finish it. If you go through a great effort to
suffer for a long time, you are allowed to sneer at people who can't be
bothered. That's the surest sign of classic art.
