    I have a copy of JIS X 4051 as of today, and Martin Heijdra helped
    me find the right section. Here's what it says:

    7.11 圏点処理 圏点処理は，次による。
    a) 圏点の文字サイズは，親文字の文字サイズの 1/2 とする。
    b) 圏点は，親文字 1 文字に 1 文字だけつける。
    c) 圏点の位置は，縦書きでは親文字の外枠の右側とし，横書きでは親文字の外枠の上部
    とし，親文字の外枠に接した中心に配置する。
    d) 圏点がついた親文字列は，元の親文字の文字クラスに従う。
    e) 圏点クラスの文字種は，JIS X 4052 の附属書 2 による。

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