It gets complicated once you try to consider what happens to vertical
scripts in such a layout mode. They can't very well be written
upside-down. See Unicode Technical Note #22 for some discussion on
the topic.

Note that there's a difference between vertical text and rotated text.
In some cases they look the same (pure Latin). In others, they don't
