Still basically the same story with 1.3.0rc1, in some cases this test
fails, but I haven't consistently figured out what triggers it.

The culprit is right here: it should read “Malnovaĵoj”, but there’s a
question mark instead of ‘ĵ’.

Could it be that you’re not running tests in a UTF-8 locale?

Thanks,
Ludo’.

Thanks for taking a deeper look!

Yes, on tests.reproducible-builds.org, one build is run in the C locale,
the other in various UTF-8 locales (somewhat arbitrarily tied to
architecture exactly which UTF-8 locale is used). I'm guessing
buildd.debian.org use C.UTF-8, since it builds fine there.

So now the question is what to do; should tests be able to assume a
UTF-8 locale?

Should I try to adapt the test to work in C?

Should I workaround it in the Debian packaging by forcing to use a UTF-8
locale (on Debian, the only one definitely available is C.UTF-8, which
isn't in upstream glibc, and thus not in guix itself).

Since it’s the only test that makes this assumption, you can choose
whichever option sounds best to you.  In Guix proper, I’d rather assume
we’re running in a UTF-8 locale.  If that’s not a good option for you,
you could patch this one non-ASCII character.

HTH!

Ludo’.
