Re: [clreq] Style for counter in ordered list using Chinese character.

Is this helpful as a base to work with for a new section?


# Chinese lists & counters

Chinese lists use a number of different counter styles. Patterns for these counter styles are described in the W3C Note Custom Counter Styles.  The various types of counter style are named and grouped here per their description in that specification.


## Bulleted lists

_What is the preferred shape of bullets?_



## Fixed counter styles

Common counter styles include the use of a fixed set of characters within circles or parentheses. These include:

- circled-decimal (eg. ⓪ ① ② ③ ④ ⑤ ⑥ ⑦ ⑧ ⑨ ⑩ .. ㊿ )
- circled-ideographic (10 symbols only: ㊀ ㊁ ㊂ ㊃ ㊄ ㊅ ㊆ ㊇ ㊈ ㊉ )
- parenthesized-ideograph (10 symbols only: ㈠ ㈡ ㈢ ㈣ ㈤ ㈥ ㈦ ㈧ ㈨ ㈩ ) 

These counters are separated from list items by a space only.

## Numeric counter styles

The numeric counter system interprets the list of counter symbols as digits to a "place-value" numbering system, similar to the common  decimal counter style. The first counter symbol in the list is interpreted as the digit 0, the second as the digit 1, and so on. Counter styles used in Chinese include:

- decimal (eg. 1 2 3 4 5 6 7 8 9 10 … 23 … 234 )
- cjk-decimal (eg. 一 二 三 四 五 六 七 八 九 一〇 … 二三 … 二三四 )

The counter style suffix for lists containing Han character counters is 、 [U+3001 IDEOGRAPHIC COMMA]. _What about decimal european digits? And are fullwidth digits used?_



## Alphabetic counter styles

The alphabetic counter system interprets the list of counter symbols as digits to an alphabetic numbering system, similar to the default lower-alpha counter style, which wraps from "a", "b", "c", to "aa", "ab", "ac". Alphabetic numbering systems do not contain a digit representing 0; so the first value when a new digit is added is composed solely of the first digit. Chinese alphabetic counter styles include: 

- cjk-earthly-branch (eg. 子 丑 寅 卯 辰 巳 午 未 申 酉 … 子戌 … 子午巳 )
- cjk-heavenly-stem (eg. 甲 乙 丙 丁 戊 己 庚 辛 壬 癸 … 乙丙 … 乙丙丁 )

The counter style suffix for lists is 、 [U+3001 IDEOGRAPHIC COMMA].



## Other counter styles

These are counter styles that don’t quite fit into the aforementioned categories. The algorithm for computing counters is given in the Counter Styles specification.  They include:

- simp-chinese-informal (eg. 一千一百一十一) 
- simp-chinese-formal (eg. 壹仟壹佰壹拾壹)
- trad-chinese-informal (eg. 一千一百一十一) 
- trad-chinese-formal(eg. 壹仟壹佰壹拾壹)

The counter style suffix for lists is 、 [U+3001 IDEOGRAPHIC COMMA].



## Orientation of counters in vertical lists

Fixed and decimal numeric counters (including their suffixes) generally run horizontally at the start of a vertical line of text.
