This is a followup to ed0cd12a82, which
adds the C.UTF-8 locale to the glibc package, and
ee4e79f871, which changed the default to
“C.UTF-8” for ‘guix’ commands.
Fixes a bug whereby starting ‘guix’ in an environment where the LC_*
variables are unset would start it in the “C” locale:
echo '(pk (setlocale LC_ALL))' | guix shell -CW coreutils -- guix repl
This would lead to breakage for commands such as ‘guix substitute’ that
need to run in a UTF-8 locale.
* gnu/packages/aux-files/guile-launcher.c (main): Try “C.UTF-8” before
“en_US.UTF-8”. Do that also when the current locale is “C”.
* guix/ui.scm (install-locale): Likewise.
