unicode - 所有 Unicode 左括号/右括号的列表

Question

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

Answer 1

有一个plain-text database有关 Unicode 联盟提供的每个 Unicode 字符的信息；格式在Unicode Annex #44中描述。 。主要信息包含在UnicodeData.txt中。 。开始和结束标点字符用 Ps 表示。 (标点符号开始)和 Pe (标点符号结束)位于 General_Category 字段(第三个字段，由 ; 分隔)。寻找这些角色，您就会找到您要找的东西。

请注意，并非所有您认为括号中的字符都会列出；例如，引号(包括“«»”)。用 Pi 表示和Pf (开头和结尾的标点符号)，因此您可能也想包含这些内容。还有一些字符，例如 <和> 、 在某些上下文(例如 HTML/XML)中用作括号，而它们在 UnicodeData.txt 中被视为数学符号 ( Sm )。那些你必须手动找到的；没有预先确定的列表。

这是一个用于获取此信息及其输出的快速 Bash 脚本。我已经包含了括号和引号。 (注意:在某些 Bash 实现上，UTF-8 打印有一个错误，导致它将 U+00AB“«”和 U+00BB“»”打印为“？”，并且某些终端无法呈现所有字符正确。)

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
