To my mind it might be a plus for Emacs to pass it's LANG along in this
particular situation as UNIX style sub-processes aren't going to pick up
the correct locale themselves and so will, presumably, default to "C",
no matter what the locale should be.

eg. running the locale command from within Emacs:

LANG=
LC_COLLATE="C"
LC_CTYPE="C"
LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_ALL=

vs running it from terminal.app:

LANG="en_GB.UTF-8"
LC_COLLATE="en_GB.UTF-8"
LC_CTYPE="en_GB.UTF-8"
LC_MESSAGES="en_GB.UTF-8"
LC_MONETARY="en_GB.UTF-8"
LC_NUMERIC="en_GB.UTF-8"
LC_TIME="en_GB.UTF-8"
LC_ALL=
