Are these mappings correct? I always thought that pinyin and bopomofo used
the same marks for tones.
My personal list for bopomofo tones would be this:
* 1st: U+0304 (COMBINING MACRON)
* 2nd: U+0301 (COMBINING ACUTE ACCENT)
* 3rd: U+030C (COMBINING CARON)
* 4th: U+0300 (COMBINING GRAVE ACCENT)
* light: U+0307 (COMBINING DOT ABOVE)
It is the same list that I would use for pinyin, apart the light tone, that
in pinyin is a small circle:
* light: U+030A (COMBINING RING ABOVE)
(There is also another difference: the mark for the light tone is normally
dropped in pinyin, while bopomofo often drops the mark for 1st tone).
What is wrong with this list? Why did Unicode choose spacing marks for
Bopomofo tones in the Big-5 table?
