Ah, sorry, I was wrong, and right too. And Dave, you also were wrong and
right.

Linux indeed pads some double-width characters with spaces. (According to a
comment in drivers/tty/vt/vt.c this is done for Unicode 5.0.) I wonder if
there is any chance of getting Linux to pad all double-width charactes with
spaces.
