所有Unicode的打开/关闭括号列表？

Question 1

每个unicode类括号字符（包括例如{}[]()<>）的列表是什么？搜索Unicode字符的好方法是什么？

Question 2

有一个纯文本数据库，其中包含Unicode联盟提供的有关每个Unicode字符的信息。该格式在Unicode附件＃44中进行了描述。主要信息包含在UnicodeData.txt中。在General_Category字段（第三个字段，以分隔）中，打开和关闭标点符号用Ps（标点开始）和Pe（标点结束）表示;。寻找那些角色，您会找到想要的东西。

请注意，可能不会列出您认为方括号的所有字符；例如，引号（包括“«»”）。以Pi和表示Pf（初始和最终标点符号），因此您可能还希望包括它们。某些字符（例如<和）>在某些上下文中（例如HTML / XML）用作括号，而Sm在UnicodeData.txt中它们被视为数学符号（）。您将需要手工找到的那些；没有预先确定的清单。

这是一个快速的Bash脚本，用于获取此信息及其输出。我已经包括了方括号和引号。（注意：在某些Bash实现中，UTF-8打印存在一个错误，导致该错误将U + 00AB“«”和U + 00BB“»”打印为“？”，并且某些终端无法渲染所有字符正确地。）

while IFS=';' read number name category rest
do 
    if [[ "$category" =~ Ps|Pe|Pi|Pf ]]
    then 
        printf "%s (U+%s, %s): \u"$number"\n" "$name" "$number" "$category"

Question 3

Unicode中没有规范的列表，您必须定义自己的列表。您可以首先使用Python的unicodedata模块浏览Unicode数据库。请注意，<>即使它们具有其他正式含义（即小于和大于符号），也不会找到像这样用作括号的内容。

#!/usr/bin/env python2.7

import re
import unicodedata

for i in range(0x10000):
    char = unichr(i)
    category = unicodedata.category(char)
    name = unicodedata.name(char, '')
    if ('bracket' in name.lower() or 'paren' in name.lower()
            or category in ['Ps', 'Pe']):
        print 'U+%04x %s %s %c' % (i, category, name, char)

Question 4

最近的Unicode版本添加了一个属性Bidi_Paired_Bracket，该属性提供Unicode认为是该问题的答案。这与被镜像的镜像不同。截至Unicode 8.0，共有60个括号对。下表将每个映射到其配合。第一列给出一个代码点。第二个给出了引入的Unicode版本。第三个显示映射，最后一列按字符名称给出映射。另外，为了查看Unicode字符数据库，Perl5与Unicode :: UCD模块打包在一起，具有许多检查功能，包括Perl v5.22中的新功能，这些功能将输出给定代码点的所有属性的值。CPAN上的Unicode :: Tussle提供类似的功能和其他功能

Question 6

“类括号”字符的想法或多或少可以通过Ps（标点符号，打开）和Pe（标点符号，关闭）的常规类别（gc）属性值来识别。该类别包含几十个成对的标点符号，大部分不包括引号（类别Pi和Pf）。

在编程中，许多语言都有用于测试字符的通用类别的工具，例如\p{Ps}在Perl中。

如果只需要一些列表，则可以使用fileformat.info上的Unicode字符类别信息。

通常，搜索Unicode字符的方式取决于您要查找的内容和条件。在许多情况下，一般类别是一个很好的起点。

Question 7

搜索Unicode字符的好方法是什么？

显然，这取决于您打算做什么。我建立了网站http://write-math.com。在我的单身汉论文期间，我创建了一个符号分类器（现在在本网站的“分类”下），使用户可以绘制符号并获得LaTeX / unicode结果（目前仅支持369个符号）。如果您想排版文档并搜索单个特定字符，这非常好，您可以知道它们的外观/如何调用，但不知道如何使用LaTeX（或用于排版的任何东西）编写它们：
