Windows记事本如何解释字符 [英] How windows notepad interpret characters

问题描述

我想知道Windows如何解释字符，例如：

I was wondering how windows interpret characters, for instance:

我用3位字节的code> E3 81 81 。
这些字节是编码为UTF-8的ぁ字符。

I maked a file with an Hexeditor with the 3 bytes E3 81 81. Those bytes are the "ぁ" character encoded as UTF-8.

我打开记事本并显示ぁ

我没有指定文件的编码，我刚刚创建了字节。
和记事本正确解释。

i dont specified the encoding of the file, i just created the bytes. and the notepad interpret it correctly.

记事本是否猜测可能是什么编码？
或是十六进制编辑器，用特定编码保存这些字节。

Is the notepad guessing what encoding probably is? or is the Hex editor saving those bytes with a specific encoding.

推荐答案

如果文件只包含这三个字节，那么根本就没有关于使用哪种编码的信息。

If the file only contains these three bytes, then there is no information at all about which encoding to use.

一个字节只是一个字节，没有办法在其中包含任何编码信息。此外，十六进制编辑器甚至不知道您打算将数据解码为文本。

A byte is just a byte, and there is no way to include any encoding information in it. Besides, the hex editor doesn't even know that you intended to decode the data as text.

记事本通常使用ANSI编码，因此如果将文件读取为UTF- 8然后它必须根据文件中的数据猜测编码。

Notepad normally uses ANSI encoding, so if it reads the file as UTF-8 then it has to guess the encoding based on the data in the file.

如果将文件保存为UTF-8，记事本将放置BOM（字节顺序标记） EF BB BF 在文件的开头。

If you save a file as UTF-8, Notepad will put the BOM (byte order mark) EF BB BF at the beginning of the file.
