The ``some lines are skipped'' part is indeed solved.  But the other
problems mentioned in my bug report are still there.  For example,
compare the "South Asia" and "Bengali" lines with a graphics display:
the number and screen position of the `?' question marks displayed
on a tty instead of non-ASCII characters do not match those displayed
on a graphics terminal.
