Bug#892989: weird chars found in dpkg output

[Harald Dunkel]

systemd is version 232-25+deb9u2.

Please remember that we are talking about running apt and dpkg
using root to setup a server. Personal user desktop preferences
don't matter here.

I do not set LANG or LC_something for system administration.
Just using the default system environment suggested by the
locales postinst script ("None").

The remote system I called "apt install" or "apt upgrade" on
was a LXC container bootstrapped for Stretch:

        # lxc-create -t debian -n tisde9i002 -- -r stretch
        # chroot /var/lib/lxc/tisde9i002/rootfs passwd
        # lxc-start -n tisde9i002 -F

        login as root

        # apt update
        # apt install ebtables
        :
        :
        Setting up libxtables12:amd64 (1.6.0+snapshot20161117-6) ...
        Processing triggers for systemd (232-25+deb9u2) ...
        Setting up ebtables (2.0.10.4-3.5+b1) ...
        Created symlink 
/etc/systemd/system/multi-user.target.wants/ebtables.service → 
/lib/systemd/system/ebtables.service.
        update-rc.d: warning: start and stop actions are no longer supported; 
falling back to defaults
        Setting up libnfnetlink0:amd64 (1.0.1-3) ...
        Setting up libip6tc0:amd64 (1.6.0+snapshot20161117-6) ...
        Setting up libnetfilter-conntrack3:amd64 (1.0.6-2) ...
        :
        # systemctl disable ebtables
        Synchronizing state of ebtables.service with SysV service script with 
/lib/systemd/systemd-sysv-install.
        Executing: /lib/systemd/systemd-sysv-install disable ebtables
        # systemctl mask ebtables
        Created symlink /etc/systemd/system/ebtables.service → /dev/null.
        #


BTW, "apt purge ebtables" doesn't remove /etc/systemd/system/ebtables.service
On the next "apt install ebtables" it was still masked.
