Do you have installed twice glibc-locales?

 1. in your user default profile; what you already did, I guess.
 2. in your root profile (roughly speaking the locale used by the
daemon) -- maybe adjust systemd or other.

Well, this should fix the issue when you invoke "guix <command>".
For the other issue (peek), I do not know.

Hope that helps,
