I don't understand why your choice of LANG should depend on the
interactive-ness of an invocation.

Changing from a hard-coded version that matches your preferences to a
configurable version that respects LANG may require a bit more care on
the user side (they have to ensure LANG is set in their crontab,
etc.).  However, setting your locale to match your preferences is not
that much work.  For example:

  export LANG=en_US.UTF-8

and you're done.  The upside of a configurable language is that the
user gets output in their preferred encoding (UTF-8 or not) and—with a
bit of additional gettext work—in their preferred language.  That
sounds like a fair trade to me.
