问题描述

为什么度数符号与Unicode的UTF-8不同?

Why Degree symbol differs from UTF-8 from unicode?

根据: http://www.utf8-chartable.de/和 http://www.fileformat.info/info/unicode/char/b0/index.htm

unicode是 B0 ，但UTF-8是 C2 B0 怎么了！

unicode is B0 but UTF-8 is C2 B0 How come!??

推荐答案

UTF-8是一种使用可变字节数(字节数取决于代码点)对UTF字符进行编码的方法.

UTF-8 is a way to encode UTF characters using variable number of bytes (the number of bytes depends on the code point).

U + 0080和U + 07FF之间的代码点使用以下2个字节的编码:

Code points between U+0080 and U+07FF use the following 2-byte encoding:

110xxxxx 10xxxxxx

其中x代表要编码的代码点的位.

where x represent the bits of the code point being encoded.

让我们考虑U + 00B0.以二进制形式，0xB0为10110000.如果将这些位替换为上述模板，则得到:

Let's consider U+00B0. In binary, 0xB0 is 10110000. If one substitutes the bits into the above template, one gets:

 11000010 10110000

以十六进制表示的是0xC2 0xB0.

In hex, this is 0xC2 0xB0.
