Re: [clreq] 标点符号的SVS (#637)

发现我提交的问题 #701 重复了，在这里粘贴一遍。

[StandardizedVariants-16.0.0.txt](https://www.unicode.org/Public/16.0.0/ucd/StandardizedVariants.txt)定义了数十种东亚标点位置与宽度的变体，文档对此尚未提及。

```

需要添加的内容包括但不限于：
- [ ] 在“5. Punctuation & inline features 标点符号与其他行内特性”中找个位置介绍标点变体序列，可以是总体介绍，也可以在每种标点符号下介绍。另外：

  - [ ] 更新5.1中的该提示：

    > CJKV punctuation marks use different glyphs which are visually distinct between languages. Unicode currently does not distinguish each of them with unique codepoints. Usually, we use typefaces corresponding to the locale of the written text or have the layout engines adjust the punctuation marks according to the languages automatically.
    >
    > 中日韩越意音文字标点符号有地区上的字形与形态差异，但Unicode并未对其区分码位，标点多有共用。通常，排版时使用相应的字体进行配置，或由排版引擎自动调适。
  - [ ] 介绍网络内容作者对标点变体使用的现状，并指导作者何时可使用变体、何时应使用变体、是否应当总是使用明确的变体（尤其是对于蝌蚪引号）。
- [ ] 在“6.3.2 Punctuation Width Adjustment 标点符号的宽度调整”中介绍，被变体选择符标记为全宽/半宽的标点，或被标记为位于角落/中央的标点，是否应当同非变体标点一样调整宽度。
- [ ] 在“A. Punctuation marks in Chinese 中文标点符号表”汇总这些变体。
- [ ] 在“B. Glossary 词汇表”中解释“变体序列”与“变体选择符”。
