    U+3031 and its voiced variant U+3032 are only appropriate to use in
    vertical layout. These two characters are AFAIK only used in Japanese,
    and the current recommendation is not to use them at all.

    Unicode contains doubles of some CJK punctuation marks, one form for
    vertical layout and one for horizontal layout. It is inappropriate to
    use a vertical punctuation mark in horizontal writing, and vice versa.
    I wonder why this was not solved in the same way as with LTR/RTL, where
    some characters, e.g. parantheses, are mirrored when changing the
    reading direction. In CJK this is a matter of turning the characters 90
