Re: Representation of neutral tone in pinyin and bopomofo

Pinyin orthography changed last year. Rule 7.3 of GB/T 16159-2012
<http://www.lshk.org/sites/default/files/zhengcifa_0.pdf> stipulates
that a preceding dot (probably U+00B7 or U+2022) be used to indicate
neutral tone in dictionaries, as had been common practice among many
dictionary makers anyway. When there is alternation between neutral and
another tone two tone marks may be used simultaneously, as in /zhī·dào/
(知道).
