windows-7 - The Chinese path of the Windows command line window that pops up with the GVim :!% command is garbled. How to solve it?

Question

Open a file in a Chinese directory. As long as the current directory of GVIM is not the Chinese directory or the file name is Chinese, enter :!% in the command mode, this window will pop up and an error will be reported... English file names or English paths are no problem.

Answer 1

This seems to have nothing to do with Chinese or English, let’s take a look at the two screenshots:

According to your description, I operated a file with a Chinese file name and an English file name in sequence, and the results displayed were the same.

The key is :!% 命令到底是什么意思。:! 是在 vim shell 里执行一个 shell 命令，而 % 指代当前的文件名于是你的操作等于把文件名当作一个 command 来执行了，那么不管是中文还是英文都会报 command not found, which is the "system cannot find the specified path" you see under windows.

I don’t know if you type :!% 命令的目的是什么呢？如果是为了打开文件，那么可以 :!open %. This can open the file content in the current buffer under Mac. As for windows, I am not sure.

Answer 2

gvim will send characters to the system in utf-8 format by default. Refer to h:termencoding
In your case, the Chinese characters in utf-8 are sent to the system cmd, and then displayed through cp936 encoding. So the display is garbled.
You can test it like this to verify: set encoding=cp936 to force cp936 display; then !%, execute the file, the garbled file name popped up by cmd is consistent with the content you force to display

Answer 3

I recently discovered a good way. It was clear before that the CMD window was "cp936" and the file name sent by GVIM was "UTF-8".

So, use GVIM's iconv() function to convert the "UTF-8" inside GVIM into "cp936" and pass it to CMD. In this way, the previous problem can be solved.
I can currently use this sentence to complete it:

:execute "!".iconv('"'.@%.'"','UTF-8','cp936')

You can also have other functions with slight modifications.
