fresh leap 42.3 freshly installed from scratch

booting up, when pressing esc on the suse logo animation, it reverts back to
displaying technical loglines about services and various stuff. At the kind of
the beginning of the many log messages and service statuses displayed, there is
this log line being shown on screen:

Created slice system-systemd\x2dfsck.slice

I can not find this in journalctl -b
nor in dmesg -e

but the part "\x2d" doesnt seem right and I have found some bugreport about it
with redhat

<https://bugzilla.redhat.com/show_bug.cgi?id=1313473>
 Bug 1313473 - dashes are unicode \x2d in systemd warning message in journal 


but they (systemd? upstream?) claim it wasnt a bug?
