I don't know how internally this is done. Maybe Ian can comment on this.

The language was set through  + system preferences + International.
After the setting, run 'env' in Terminal.app and there's a line:

  LANG=en_GB.UTF-8

When starting Emacs from Terminal.app by running:

  /Applications/Emacs.app/Contents/MacOS/Emacs -q

It picks up that setting automatically i.e. if you check variables such
as default-file-name-coding-system, it says UTF-8.

But if you start Emacs from dock, it is something else.

It will be nice to have that. The current behaviour gave me a big shock
when I first used Emacs.app.
