[Message part 2 (message/rfc822, inline)]
If a multi-column character is crossing the start column of a intended
rectangle, no characters are deleted in the same line.
For example, type 'C-x r d'(delete-rectangle) from column 1 to column 4
of the text below, the second line characters are not deleted.
01234
一二4
01234
result:
04
一二4
04
This does not apply to #'kill-rectangle.
kill-rectangle result:
04
一4
04
To keep the table layout, multi-column characters crossing the start(or
end) column of the rectangle should be replaced with space characters
of the same width before deletion.

Thanks. Since it sounds like everyone agreed with the solution I
proposed, I have now installed that on the master branch, and I'm
therefore closing this bug.
