Thank you very much.

I looked at the Linux kernel sources, and found from drivers/tty/vt/vt.c a
table of characters which will be automatically padded with space when writing
the glyph to the console. It recognizes two-column characters from Unicode
5.0. I try to get a patch into Linux itself which would extend support for
automatic padding to include current Unicode multi-column characters.

Whether this succeeds or fails, I'll report it here. This might take some time
though, I'm afraid. It probably would fix this alignment issue for good.
