I'm not 100% confident, but I believe that this bug may have been fixed upstream
as part of a subsequent release.  I don't find any clearly locale-related
differences when comparing the current output of the comparative builds[1] of
grub2 in the Reproducible Builds test infrastructure for Debian.

The upstream commit that I think is the most likely candidate to have fixed
the problem is this one:

  http://git.savannah.gnu.org/gitweb/?p=grub.git;a=commit;h=f42266a8a2a4215e4ffe419b8092bdf9ced33e8e

...but I haven't tested / confirmed that.

Regards,
James
