        Emphasis mark size is 1/2 of the size of the main (parent) characters.
    b) $B7wE@$O!$?FJ8;z(B 1 $BJ8;z$K(B 1 $BJ8;z$@$1$D$1$k!#(B
        There is only one emphasis mark per parent character.

        The placement of emphasis marks is on the right side of the outer frame
        of the parent character for vertical text, and above the outer frame
        of the parent character for horizontal text, abutting to the outer
        frame of the parent character and centered.
    d) $B7wE@$,$D$$$??FJ8;zNs$O!$85$N?FJ8;z$NJ8;z%/%i%9$K=>$&!#(B
        Character strings with emphasis marks take the character class of
        the original parent characters.

        Characters in the emphasis character class are based on appendix
        2 of JIS X 4052.

    >Apparently the list of shapes endorsed by this spec is in appendix 2 of
    >JIS X 4052?

    Yes indeed. Tha appendix has the following characters:

    - sesame dot (also called centered comma, so it is indeed, as Asmus
                 described, a centered comma)
    - white sesame dot (white hollow centered comma)

    - black circle (U+25cf)

    - white circle (U+25cb)

    - black up-pointing triangle (U+25b2)

    - white up-pointing triangle (U+25b3)

    - bullseye (double circle) (U+25ce)

    - fisheye (U+25c9)

    The appendix also has the following remarks:
    1) The above list designates the characters used as emphasis marks.
    2) By private agreement, parties can use other characters in
        addition to those above as emphasis marks. In such a case,
        the additional characters have to be listed in documentation.
    3) The size of the emphasis marks is defined by JIS X 4051.
    4) The design of the concrete shape of the emphasis marks is outside
        the scope of this standard.
