Some suggestions of symbols in TC

The 4 suggestions are also applicable in SHSans.

## (1) Brackets are good to be positioned at center

In Traditional Chinese typesetting, all symbols are usually considered as a full-width character.
Not only ，。：！？, but also brackets.
(Note: In Japanese or Simplified Chinese, brackets are considered as a half-width character with a half-width space.)
Most of Traditional Chinese text is Betagumi, Japanese style brackets looks have too large space. And it's not beautiful.


## (2) Proportional width of symbols looks strange

Since the symbols are positioned at center, they looks too crowded when proportional width is ON.
50% width is not ideal.
I suggest that remove palt information of the symbols. (But keep hwid information for advanced users.)


## (3) Quotation or Apostrophe

Character U+2019 is used as a quotation mark and a apostrophe.
The width of this character is a difficult historical problem.

However, in Traditional Chinese text, quotation marks are usually be 「」.
In most cases, U+2019 is used as a apostrophe. And very few as a quotation mark.
(In Simplified Chinese, the story is different.)
So I suggest that U+2018 and U+2019 is better to be designed in a proportional width. (like Japanese or Korean ones.)



## (4) Tone marks of Bopomofo

The second, third, fourth tone mark is too small.
They should be the same size of Bopomofos.

And, the direction of second tone mark is wrong. (Correct: Left-down to right-up.)
