As Ricardo mentioned, it comes from the configuration of your locales
[1].

First, plain leads to the warning message.

--8<---------------cut here---------------start------------->8---
$ guix shell -C julia
[env]$ julia

Second, let add and configure the locale:

--8<---------------cut here---------------start------------->8---
$ guix shell -C julia glibc-locales
[env]$ GUIX_LOCPATH=$GUIX_ENVIRONMENT/lib/locale julia
               _

No more warning.

The manual explains how to setup globally.  Let me know if you need more
details.
