Question

每个类似于unicode括号的字符的列表是什么（包括，例如：{}[]()<>）？搜索unicode字符的好方法是什么？

Answer 1

有关Unicode Consortium提供的每个Unicode字符的plain-text database信息;格式在Unicode Annex #44中描述。主要信息包含在UnicodeData.txt中。打开和关闭标点符号在General_Category字段（由Ps分隔的第三个字段中）用Pe（标点符号开头）和;（标点符号结束）表示。寻找那些角色，你会找到你想要的东西。

请注意，并非列出您认为括号的所有字符;例如，引号（包括“«»”）。用Pi和Pf（初始和最终标点符号）表示，因此您可能也希望包含这些标点符号。并且某些字符（如<和>）在某些上下文（例如HTML / XML）中用作括号，而在UnicodeData.txt中它们被视为数学符号（Sm）。那些你必须手工找到的;没有预先列出的那些。

这是一个快速的Bash脚本来获取此信息及其输出。我已经包括了括号和引号。（注意：看起来Bash的UTF-8打印有一个错误导致它不能正确打印U + 00AB“«”和U + 00BB“»”，这就是为什么那些显示为？）。

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"
    fi
done <UnicodeData.txt

Answer 2

在Unicode中没有这样的规范列表 - 你必须定义自己的列表。您可以先使用Python的unicodedata模块来探索Unicode数据库。请注意，即使它们具有其他官方含义，也不会发现用作括号的<>之类的内容，即低于和大于符号。

#!/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)

输出：

最近的Unicode版本添加了一个属性Bidi_Paired_Bracket，它提供了Unicode认为是这个问题的答案。这与镜像的不同。 Unicode 8.0中有60个括号对。下表将每个映射到其配对。第一列给出了一个代码点;第二个给出了它引入的Unicode版本;第三个显示映射，最后一列显示字符名称的映射。此外，为了查看Unicode字符数据库，Perl5与模块Unicode :: UCD一起打包，其中包含许多用于检查事物的函数，包括Perl v5.22中的新函数，它们将输出给定代码点的所有属性的值。 CPAN上的Unicode :: Tussle提供类似和其他功能

Answer 5

“支架式”字符的概念可能或多或少地用Ps（标点符号，打开）和Pe（标点符号，关闭）的常规类别（gc）属性值标识。此类别包含几十个成对的标点符号，大多数不包括引号（Pi和Pf类别）。

在编程中，许多语言都有用于测试角色的一般类别的工具，例如Perl中的\p{Ps}。

如果您只需要一些列表，可以使用fileformat.info上的Unicode Character Categories信息。

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

Answer 6

搜索unicode字符的好方法是什么？

这显然取决于你打算做什么。我建立了网站http://write-math.com。在我的单身汉论文中，我创建了一个符号分类器（现在在这个网站上＆＃34;分类＆＃34;），这使用户可以绘制符号并获得LaTeX / unicode结果（目前只支持369个符号））。如果你想要排版文档并搜索单个特定字符，你知道它们是什么样子/如何调用它们而不是如何用LaTeX（或者你用于排版的任何东西）来编写它们，这是非常好的：

enter image description here

它还具有符号搜索功能。它仍处于繁重的发展阶段，但该数据库中有1166个符号。

对于括号：

unicode.xml（来自http://www.w3.org/2003/entities/2007doc/#source）也值得一试。

Answer 7

http://xahlee.info/comp/unicode_matching_brackets.html

这是一个优秀且非常全面的网站（对于括号和其他所有内容），看起来他们都使用Arial，sans-serif显示它们，所以如果你能看到这个字符，那么它应该适用于良好的浏览器支持。

所有unicode的开/关括号列表？
