如何查看emacs中文件的编码？ [英] How to see the file's encoding in emacs?

问题描述

我找不到当前文件的编码，如何显示？

I don't find the encoding of current file, how to display it?

您可以看到文件中有一些中文字符，但我不知道它的编码是什么。

You can see there are some Chinese characters in the file, but I don't know what the encoding it is.

有没有办法让它始终在emacs GUI上显示？

Is there any way to let it always show on the emacs GUI?

推荐答案

您可以在模式行中用 U 看到缓冲区是Unicode格式的，如果将鼠标放在其上，它将显示为工具提示当前缓冲区编码。

You can see with the U in the mode-line that your buffer is in Unicode, if you put the mouse over it it will show in a tooltip the current buffer encoding.

• 您可以使用 Ch 查看当前编码 v 缓冲文件编码系统 RET


• 您可以使用 Cx RET f
$ li $更改下一次保存的整个缓冲区编码b
• 您还可以更改检测到的编码以强制使用另一种编码，并使用 Cx 重新加载文件 bd> RET r


• 您只能使用 Cx RET c


• 还有其他可能，请查看 Cx RET Ch


• 如果文件混合编码混乱，您可以使用 Mx recode修复部分 -region


• 如果您想自己进行诊断：
  
  
  
  
  • 您可以使用从字面上查找Mx查找文件
  
  
  • 打开文本文件而无需任何解码或启发式操作，也可以更接近金属（十六进制编辑器）和 Mx hexl-find-file
  
  
  • you can see the current encoding with C-hv buffer-file-coding-system RET
  • you can change the whole buffer encoding for next save with C-xRETf
  • you can also change the detected encoding to force an other one and reload the file with C-xRETr
  • you can set an encoding for the next I/O command only with C-xRETc
  • there are some other possibilities, take a look on C-xRETC-h
  • if the file is a mess with mixed encodings, you can fix portions with M-x recode-region
  • if you want to make a diagnostic by yourself:
    • you can open a text file without any decoding or heuristic with M-x find-file-literally
    • or you can go closer to the metal (hex editor) with M-x hexl-find-file

    在缓冲区内，如果您对字符编码/细节感兴趣，请将其放在中文字符上，然后 Cu Cx = 会有所帮助。 （不带 C-u 的内容仅显示有关该字符的一些信息，并且编码不属于该字符。）

    Inside a buffer, if you are interested by a character encoding / details, put the point on a chinese char and C-uC-x= will help. (The same without the C-u shows only a few informations about the character, and the encoding is not part of it.)
