If the "Locale" setting in the configuration file is set to "-" then vnstat
will use the value in the LC_ALL variable as described in the configuration
file comment and the man page. Your 'locale' output shows that LC_ALL isn't
set so vnstat will use an empty value resulting in some default formatting.

The daemon doesn't care about the locale setting. It only collects the data
and saves it to the database without any locale information. That's why
modifying the locale setting in /etc/init.d/vnstat will not affect the
output of the vnstat command itself.
