Output angle symbol in C

Question

I want to create a console application for phasor* addition in C.

I want C to display the ∠ symbol. I don't know how to make C to display UNICODE. I simply tried printf("∠"); but it printed a question mark in a box. I'm using MinGW.

Thanks in advance.

*phasor is an AC electric topic.

That � question mark in a box could be [glyph 0](https://learn.microsoft.com/en-us/typography/opentype/spec/recom#glyph-0-the-notdef-glyph). The ∠ symbol (angle) is e.g. in the `DejaVu Sans Mono` or `Unifont` font… — JosefZ, Mar 28 '21 at 13:45

to print the phasor symbol use "\u2220" if you are using c99

#include<stdio.h>
int main()
{
    puts("\u2220");
}

as r3mainer pointed out Printing a Unicode Symbol in C below code works with c89

#include <stdio.h>
#include <wchar.h>
#include <locale.h>
int main() {
    setlocale(LC_CTYPE, "");
    wchar_t phasor = 0x2220;
    wprintf(L"%lc\n", phasor);
}

check this for encoding is it UTF-16 or UTF-32

It gives an error message: "universal character names are only valid in C++ and C99" and outputs `â^` – CingirakliDumbelek Mar 28 '21 at 12:00
@CingirakliDumbelek are you using c89 ? – MONUDDIN TAMBOLI Mar 28 '21 at 12:04
How can I learn which version I'm using? I just installed MinGW and started coding. – CingirakliDumbelek Mar 28 '21 at 13:32
BTW This wchar_t solution isn't working. It prints a blank space. – CingirakliDumbelek Mar 28 '21 at 13:34
@CingirakliDumbelek are you executing code on cmd , terminal or in ide – MONUDDIN TAMBOLI Mar 28 '21 at 13:42
@CingirakliDumbelek edit your question and put your code – MONUDDIN TAMBOLI Mar 28 '21 at 13:43
Use `-std=c99` switch on gcc command line. – Frankie_C Mar 28 '21 at 14:33
I'm using notepad++ and nppexec plugin to run C code. I don't need to post the entire code I guess, I just want to achieve `printf("∠");` to work. Sorry for the late response. – CingirakliDumbelek Mar 28 '21 at 17:38
@CingirakliDumbelek created a new file type the code that is above check if it runs then we can find what problem is okay – MONUDDIN TAMBOLI Mar 28 '21 at 17:45
