为什么在与UNIX / Linux环境交互时使用UTF-8编码？ [英] Why is it that UTF-8 encoding is used when interacting with a UNIX/Linux environment?

问题描述

我知道这是惯例，但为什么？有什么真正的技术原因，为什么任何其他方式将是一个非常糟糕的主意，还是只是根据编码和向后兼容性的历史？另外，不使用 UTF-8 的其他编码（最引人注目的是 UTF-16 ）？

编辑：通过交互，我主要是指 shell 和 libc 。

解决方案

部分原因是文件系统期望NUL（'\0'）字节终止文件名，因此UTF-16会工作不好您必须修改很多代码才能进行更改。

I know it is customary, but why? Are there real technical reasons why any other way would be a really bad idea or is it just based on the history of encoding and backwards compatibility? In addition, what are the dangers of not using UTF-8, but some other encoding (most notably, UTF-16)?

Edit : By interacting, I mostly mean the shell and libc.

解决方案

Partly because the file systems expect NUL ('\0') bytes to terminate file names, so UTF-16 would not work well. You'd have to modify a lot of code to make that change.
