如何使用 *nix 中的控制台工具将 uXXXX unicode 转换为 UTF-8
问题描述：
我使用 curl 来获取一些 URL 响应，它是 JSON 响应，它包含 unicode 转义的国家字符，例如 u0144 (ń)和 u00f3 (ó).
I use curl to get some URL response, it's JSON response and it contains unicode-escaped national characters like u0144 (ń) and u00f3 (ó).
如何将它们转换为 UTF-8 或任何其他编码以保存到文件中?
How can I convert them to UTF-8 or any other encoding to save into file?
答
我不知道您使用的是哪个发行版，但应该包括 uni2ascii.
I don't know which distribution you are using, but uni2ascii should be included.
$ sudo apt-get install uni2ascii
它只依赖于 libc6，所以它是一个轻量级的解决方案(uni2ascii i386 4.18-2 在 Ubuntu 上是 55,0 kB)！
It only depend on libc6, so it's a lightweight solution (uni2ascii i386 4.18-2 is 55,0 kB on Ubuntu)!
然后使用它:
$ echo 'Character 1: u0144, Character 2: u00f3' | ascii2uni -a U -q
Character 1: ń, Character 2: ó
