how to change the coding of the cppdbg?

[zyt19803293899]

This is my code:

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
int main() {
    char c[] = "提供本地化界面";
    printf("hello world\n");
    printf("%s\n", c);
    printf("%d\n", sizeof(c));
    system("pause");
    return 0;
}

When I set externalConsole to true in launch.json, it is normol to display, like this:

But when I set externalConsole to false in launch.json, it is wrong to display, like this:

So I decide to change the coding of the integrated terminal, but when I enter chcp 936 and press F5, it still show 65001 on the integrated terminal after I enter chcp. The second pic has already displayed.
