From the above it looks like ioctl cannot find ldterm.dat where it looks for it
(/usr/lib/locale/C/LC_CTYPE/ldterm.dat). On my system I found it in
/usr/lib/locale/en_US.UTF-8/LC_CTYPE/ldterm.dat
I created symlink to it in /usr/lib/locale/C/LC_CTYPE/, and here's the result of the
same series of commands on fresh terminal:
