LANG is used in set-locale-environment in mule-cmds.el, but I don’t
know what is set using it.

I know almost nothing about locales in emacs. The main motivation for
setting LANG on macOS was so that external commands would be given the
correct locale, eg. spell checkers.

Would it be worth creating a function available from lisp that returns
system locale information?
