Solutions to unify middle dot usage in Traditional Chinese

Hello,

There's a problem I found about the middle dot usage in Traditional Chinese.

--Usage

Middle dot for Traditional Chinese has 3 usages list below: 

1, separates translated latin name in Hanzi, e.g. 乓餌喟

2, as decimal point in Hanzi e.g. 銝颱

3, separates book, chapter, title e.g.  閰拍駁憸具餌◣曌

In Traditional Chinese, the Middle dot should be full-width and a filled round dot in the middle.

--Codepoint

There's some codepoints general used for the middle dot in Traditional Chinese.

繚 U+00B7  MIDDLE DOT
 U+2027  HYPHENATION POINT
 U+30FB  KATAKANA MIDDLE DOT
嚗 U+FF0E  FULLWIDTH FULL STOP

And in Simplified Chinese usage, the middle dot is U+00B7.

U+00B7 from A150 and U+2027 from A145 on BIG 5 code table[1]. 

But I think U+00B7's definition more suitable for the middle dot than U+2027 / U+FF0E. 

--Solutions

Considering about interoperability and codepoint definition, I have 2 proposals.

1. use U+00B7 as general middle dot, if authors want to let it full-width, use U+30FB. But most Chinese fonts do not have the glyph, certainly fallback to Japanese font. [2]

2. use U+00B7 as general middle dot, and in Traditional Chinese subset, let glyph be full-width.
