Re: [clreq] 直立的标点符号 (#519)

这段行文比较随意,需要修改:

1. 讨论的对象,并不是`U+FE41` 这一个字符,而至少要包括「竖排字形」区块里 `U+FE10`—`U+FE1F`「CJK兼容字形」区块里 `U+FE30`—`U+FE4F`这十几个名称带有 PRESENTATION FORM FOR VERTICAL... 的标点

2. 这属于 Unicode 即编码范围的问题,但本文档的确有必要提一下。Unicode 的《[核心规范](https://www.unicode.org/versions/Unicode15.0.0/ch06.pdf)》对此已经由清晰、准确的描述,可以考虑引用或者适当改写即可。

>CJK vertical forms are compatibility characters encoded for compatibility with legacy implementations that encode these characters explicitly when Chinese text is being set in vertical rather than horizontal lines. The preferred Unicode approach to representation of such text is to simply use the nominal characters that correspond to these vertical variants. Then, at display time, the appropriate glyph is selected according to the line orientation.
