Emacs:有没有办法确定文件的编码系统？

Question

假设我打开一个文件并在那里找到

Ïåñíÿ àëüïèíèñòîâ

等等。我可以让 emacs 找到正确的编码吗？例如，AkelPad 具有这样的功能——在大多数情况下，它会打开一个具有正确编码的文件。

本页 http://www.gnu.org/s/libtool/manual/emacs/Recognize-Coding.html解释了 emacs 检测编码系统的系统。你可以在一定程度上控制它:

The variables auto-coding-alist, auto-coding-regexp-alist and auto-coding-functions are the strongest way to specify the coding system for certain patterns of file names, or for files containing certain patterns

您可能无意中禁用了此功能:

However, there may be cases that you want to read escape sequences in a file as is. In such a case, you can set the variable inhibit-iso-escape-detection to non-nil. Then the code detection ignores any escape sequences, and never uses an ISO-2022 encoding. The result is that all escape sequences become visible in the buffer.
