So, when clipper is run directly from a terminal, it uses whatever `LANG` is set in the environment; it's only when run from `launchd` in a `LANG`-less environment that it defaults to something not useful. I'd rather put the fix closer to the specific context where it is needed (ie. the plist).

For a little more context, see https://wincent.com/issues/2119 where the issue was originally reported.
