Subject: [PATCH] Fix Unicode character compatibility in `lxc config edit`
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently Unicode characters will become garbled when editing container
configs due to the unsupported user locale settings.  This patch fixes
the problem by resetting the locales to `C.UTF-8`.

Note that this is not a complete fix as it also disables the L10N as the
locales are hardcoded, the `locales-launch` remote part[1] is a solution
for this problem.

Fixes #29.
