命令行程序通过 Unicode 名称输出字母？

  • 772

Unicode 标准定义了世界书写系统的代码点和字母名称。Ubuntu (Linux) 上是否有命令行程序可以根据字母的（模糊）名称打印字母？

以下是我对此类程序的期望（名为pucc：打印 Unicode 字符——根据其名称或正则表达式打印 Unicode 字符）：

$> pucc sigma 
ͻ = 037B (greek small reversed lunate *sigma* symbol)
ͼ = 037C (greek small dotted lunate *sigma* symbol)
ͽ = 037D (greek small reversed dotted lunate *sigma* symbol)
Σ = 03A3 (greek capital letter *sigma*)
ς = 03C2 (greek small letter final *sigma*)
σ = 03C3 (greek small letter *sigma*)
...
$> pucc root
؆ = 0606 (arabic-indic cube *root*)
؇ = 0607 (arabic-indic fourth *root*)
√ = 221A (square root)
∛ = 221B (cube *root*)
∜ = 221C (fourth *root*)

...

我理解这只是对 Unicode 联盟维护的Unicode 文本文件curl/grep的 ping ，并且输出取决于系统上 Unicode 字体的可用性，但我只是想知道这是否已经可以作为命令使用或者可以使用过滤魔法来实现。

    我认为您正在寻找uninames，它是 Perl 模块的一部分Unicode::Tussle。您可以使用以下命令在 Ubuntu 上安装它：

    sudo apt install cpanminus

    这将安装 CPAN 管理器工具，然后您可以使用以下命令安装 Unicode::Tussle 模块：

    cpanm Unicode::Tussle

    现在您应该可以使用uniprops和uninames工具（其中包括，请参阅man uniprops和另请参阅部分），它们可以让您执行以下操作：

    （| cat这里只是为了显示输出，因为如果没有它，uninames会自动传输到寻呼机，使复制/粘贴变得更加困难）

    或者，查看有关特定角色的信息：
