使用 System.Text.Encoding 时.在大多数情况下，我应该使用Encoding.Unicode还是Encoding.UTF8?

推荐答案

它来自Unicode的早期. Unicode 1.0是一种16位编码，因为假定65536个代码点就足够了. Unicode 2.0放弃了此限制，但是包括Microsoft在内的Unicode的早期采用者将其编码命名为Unicode，并且一直存在.

It comes from the early days of Unicode. Unicode 1.0 was a 16 bit encoding as it was assumed that 65536 code points would be sufficient. Unicode 2.0 abandoned this restriction, however early adopters of Unicode, including Microsoft, Named their encoding Unicode and it has stuck.

如今，除非您有特定的(例如，需要与之集成的旧版软件)理由这样做，否则您应该使用UTF-8.

Nowadays you should be using UTF-8 unless you have a specific, eg legacy software you need to integrate with, reason to do so.

这样做的原因是ASCII与UTF-8二进制兼容，并且在那里有很多 ASCII码

The reason for this is that ASCII is binary compatible with UTF-8, and there is a lot of ASCII out there
