This wouldn't work correctly on machines without that locale. Here's what this produces on a Xenial box in Vagrant:

$ LC_ALL=ja_JP.cp932 ./hg version
Mercurial - ?????????(????? 3.8.1+13-9d38a2061fd8+20160519)
(??? https://mercurial-scm.org ???)

?????????????????? ??????????

The box has these locales: C C.UTF-8 en_US.utf8 POSIX

FWIW, I've tried it on the Xenial box, but unfortunately:

Looks like some container system: https://help.launchpad.net/Packaging/PPA

So I suspect that Xenial builder is probably just a regular Ubuntu Xenial image with extra packages installed, running in OpenStack.
