Re: Representation of neutral tone in pinyin and bopomofo

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.

For a quick reference, I've upload my slide about Bopomobo for eBook&i18n
workshop in Tokyo this June.[1]

And a guide by Taiwan Ministry of Education about how to print Bopomofo.[2]

I'll ask light tone in Simplified Chinese this afternoon.

Here's some example in Chinese Pinyin, but I didn't see the U+02D9 usage
here

Is it correct that:

- in bopomofo, the neutral (or light) tone is represented by U+02D9 ˙
DOT ABOVE, and in the text representation, that character follows the
bopomofo characters of the syllable (just like all the other characters
for tones)

- in pinyin, the neutral tone is typically not marked, but it may be
marked. 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.
