Oh, I see.

Not sure.  Guix does an extra ‘setlocale’ call and prints a
user-friendly and Guix-specific message when the locale is unavailable:

As an application developer, I feel that it’s the application’s job to
pay attention to that (when it matters) and it bothers me that libguile
prints its own warning (not i18n’d, not controllable, etc.), just like
it would bother me if libc were emitting such a warning.

Perhaps the REPL and the ‘guild’ script could emit such a warning, while
libguile itself would remain silent?

(I know that Perl and Bash emit a warning when ‘setlocale’ fails, while
Python doesn’t.  As for applications, I’ve seen all sorts of behaviors
ranging from silently ignoring the issue (Coreutils, sed, grep, Git,
etc.) to showing a popup window (Gramps) to emitting a warning (most
GTK+ programs).)
