Why does YaST now show lines as lqqqqqqqqqqqqqqq?

Change "Terminal-type string" from "xterm" to "linux" in Connection>Data.

in bash, type: export NCURSES_NO_UTF8_ACS=1

Permanent solution for your problem is :

For one users

cd ~

echo "export NCURSES_NO_UTF8_ACS=1" >> .bashrc

For all users

echo "export NCURSES_NO_UTF8_ACS=1" >> /etc/bash.bashrc.local
