I ran t2080 on the same machine (gcc119) to try debugging it but I could
not reproduce the test failure [1]. t0028 also passed here. Could it be
that we are building git differently? I did `gmake CC=gcc NO_CURL=YesPlease`.

The encoding inspection also seems OK here:

matheustavares@gcc119:[/home/matheustavares/git/t]perl -nle 'print unpack "H*"' trash\ directory.t2082-parallel-checkout-attributes/encoding/A.internal
74657874
matheustavares@gcc119:[/home/matheustavares/git/t]perl -nle 'print unpack "H*"' trash\ directory.t2082-parallel-checkout-attributes/encoding/utf8-text
74657874
