OK, I've found and confirmed what it is with a quick C program. The
default Locale for lib C is 'C'. It is up the program to set its locale
to match the environment using;
The Python locale module documents this, and recommends putting;
At the top of programs to make them use your locale as specified in your
Note that locale.resetlocale() is documented as "resets the locale to
the default settings", where the default is determined by
locale.getdefaultlocale(), which uses the environment.
So the "default" is determined from your environment, but "C" is used by
default... nice and confusing :-)
Should Python do setlocale(LC_ALL,"") on startup so that the "default"
locale is used by default?
