Forwarding some info from Bobby, in the hope of this may help. I haven't looked at them by myself and thus don't know if it really helps, but coincidentally, we have Bopomofo/Pinyin and ruby discussions at W3C TPAC this week.

When that's the case, U+02D9 ˙ DOT ABOVE is used. When U+02D9 is used in pinyin, where it is in the character sequence? before the syllable to which it applies (where it is displayed) or after (like in bopomofo)? When U+02D9 is used in bopomofo, it needs to be displayed before the syllable. Is the display position simply "before the nearest preceding character from the set {U+3105 ㄅ BOPOMOFO LETTER B ... U+3119 ㄙ BOPOMOFO LETTER S, U+31A0 ㆠ BOPOMOFO LETTER BU ... U+31A3 ㆣ BOPOMOFO LETTER GU}"? Thanks, Eric.
