Discussed this with Vit today: we weren't able to reproduce it on his computer but it seems the conditions under which it happened was: - terminal output, UTF8 terminal encoding - all locales set to "cs_CZ.UTF-8"
OK I managed to reproduce this: 1) as root rename /var/lib/dnf to something else 2) as normal user do 'dnf history'
