The related problems of Emacs Chinese recognition and Chinese input method

You've just started using Emacs, but when you see a previous document, there are two issues: 1. Unable to recognize the previous document's Chinese 2. Unable to switch to Chinese into the French Open to see a lot of tutorials, found that many have a little trouble, after a while groping, found that the problem can be easily solved.
Solve the Chinese identification problem: First, use the command locale to view locale settings (the following figure is the one I have corrected):


Change the environment variable directly; see what environment you use, if it is used in the current environment (the current user in this article is Tian), then execute the following command: Export lc_ctype= "ZH_CN. UTF-8 "
If this is the root user, perform the same operation. However, it should be noted that the modification is only valid for the current user environment. In other words, for example, you have modified the Lc_ctppe under the Tian user, then the root user or unmodified, you need to repair the changes.
Solve the problem of input method: about Emacs Environment, can't switch to Chinese input method because the CTRL + Space in Emacs defines the function, we just need to remove this shortcut binding. Locate the initialization configuration file for Emacs under Unbuntu. Note that it's not. emacs files like this ... There is no need to create a file like this. Some of the methods I found before were copied to copy, so we all wrote the same thing, and most of them were looking for. emacs file. The configuration file for Emacs in my Ubuntu system is:/etc/emacs/site-start.d/00debian-vars.el add a command at the end of the configuration file: (Global-unset-key (kbd "C-SPC")
Complete... It's so simple ...
