How can I fix garbled characters in visual studio 2019?

VS2019

I have a test source code in VS 2019 in C language and it has Japanese character.

#include<stdio.h>
#include<math.h>
int main()
{
printf_s("私はグエンチヴィエンです.京都情報大学院大学の新入生です\n");
printf_s("ベトナムの出身です");
int a = 2;
int b = 3;
int c = pow(a, 3) + pow(b, 4);
printf_s("%d", c);

When I compiled it it didn't show the Japanese message path. Instead it show the "?" all along the message.
I know this is called " Garbled Character" errors but don't know how to fix it
Can anyone suggest a solution for me?
Thank you very much!

What I have tried:

I have checked the "support Unicode UTF-8 for world wide language" in the Administrative language setting but it didn't work out for me
