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.
[Message part 3 (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.
