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

You are using CRT functions, those use the system locale to print characters. Check if you are using the en_US locale instead of ja_JP.

Refer to your Operating System documentation for how to change your locale.

@den2k88 I'm using en_US not ja_JP. Even when I changed my locale it still not work

There is no C locale information compatible with printf, so your characters don't "know" what to print like, and the default font is no use.
Have a look here: Unicode in C and C++ -[^] - I haven't tried it, but it looks like it may help solve your problem.
