same error with python-3.6.5-r1
happens with locale POSIX, with UTF it works
OK, even more strange. When I run the code myself, ie. /usr/lib/systemd-cron/mail_on_failure cron-lubos-lubos-6 It runs OK. When activated from cron, it gives the python error.

Is this fixed in 1.5.14? The changelog mentions "Handle sending mail_on_error when the locale is not correctly set" See-Also: https://bugs.gentoo.org/show_bug.cgi?id=685592
