If your guix-daemon is not running under a UTF-8 locale, then nss-certs
may end up being unpacked with incorrect file names (though I thought
that was supposed to be treated as an error, oh well.)

You can find the PID of guix-daemon, and then do something like:

  cat /proc/PID/environ | xargs -0 echo

and look at the value of GUIX_LOCPATH and LC_ALL there.  Both should be
valid.

Thanks,
