Subject: emacs INFO pages have "?"s instead of "'"s
Date: Sun, 31 Jan 2016 22:21:48 -0500

In emacs INFO pages, single quotes "'" appear as question marks "?" and
'echo $LANG' returns a blank line.

I am running guixSD on a headless server & logging in via the iTerm2
terminal emulator running on Max OS X... e.g. 'ssh' & 'emacs -nw'

When I log into an identical server running Debian 8, emacs INFO "'"
quotes are normal and 'echo $LANG' returns "en_US.UTF-8".

ITerm is set to UTF-8 and xterm-256color.

I am running the configuration shown below built earlier today as shown
further below.

Note: I also tried the alternate form, '(locale "en_US.utf8")', which is
commented out in the config, and observed the same behavior.

Many Thanks - George

Note/clarification: the problem is only with user accounts. root emacs
INFO "'" quotes are normal and 'echo $LANG' returns "en_US.UTF-8".

This bug is due to <http://bugs.gnu.org/22175>, which appears to be
fixed by the patch below (I tested it in a VM.)

Could you confirm that it works for you?  You would need to apply the
patch with ‘patch -p1 bugfix.patch’ in a fresh checkout of Guix, and to
run ‘./configure && make && ./pre-inst-env guix system reconfigure’ from
there.

TIA,
Ludo’.
