It's an encoding problem. Try this:
Definitely was!
$ LANG=C tree /tmp/ $ LANG=LANG=de_AT.UTF-8 tree /tmp/
The last command gives fine ascii art on UTF-8 terminals, but "funny" result on ISO... consoles.
Same happens for other commands.
I still don't know what actually changed. As of last November, when ~/.bashrc was last written, it contained:
export LANG=en_US
Either removing it, or changing it to:
export LANG=en_US.UTF-8
removes the problem, but tells me nothing about whatever changed in recent weeks that surfaced the problem. /etc/locale.conf has the same content before and after the upgrade from 15.4 to 15.5. :p
