Some remarks:
* LANG should be set, because it is in #:leaked-env-vars (see
guix/git-download.scm). I don't know whose LANG it is though
-- the user's, or the daemon's?
* To install an UTF-8 locale, you need glibc-locales (or possibly
glibc-utf8-locales) (At least, for now. Upstream has some plans
for including a C.UTF-8 locale so maybe eventually we can fallback
to C.UTF-8.)
* This locale data needs to be in $GUIX_LOCPATH.
* GUIX_LOCPATH is not leaked.
* Even if it was, I don't think that /gnu/store/...glibc-locales
would be accessible from the build container (though you could give
it a try?).
* So perhaps GUIX_LOCPATH needs to be set in the gexp in
guix/git-download.scm, + some setlocale as done by
gnu-build-system.
* Long-term, it could be interesting to remove the
‘file name = string encoded in current locale's encoding’
assumption from Guile.
* svn-download, hg-download, bzr-download and cvs-download
probably have the same issue.
Greetings,
Maxime.
