How to output € symbol in C?

Question

I don't know how to output the Euro symbol in a C99 Project, I am using CLion to develop the project and I'm using MinGW as Toolchain (I don't know if that matters).

I already searched a lot and I can't find any answer to my problem, hope someone can help me.

I already tried to do this

printf("€");
printf("\u20AC");

The output is Ôé¼, but I'm expecting €.

@bool3max like I said I am using CLion, the output and input is on CLion "Terminal" — João Neves, Dec 25 '19 at 20:59

On the bottom of your screen there should be the current file encoding. Is it set to UTF-8 or something like ISO-8859-1? — Martin Fink, Dec 25 '19 at 21:04
Try `printf("\xE2\x82\xAC");` Those 3 bytes represent the euro symbol in the UTF-8 encoding. Though the code in your question should produce the desired result. — bool3max, Dec 25 '19 at 21:06
@Saucy Goat I already read that post and I didn't understand... — João Neves, Dec 25 '19 at 21:06
That's what I have on my machine too, but I am able to print the symbol there. The problem then is probably that the CLion terminal is set to the wrong encoding. If you execute your program on a terminal that is configured to use UTF-8, your code *should* work right. — Martin Fink, Dec 25 '19 at 21:07
Well then your encoding is wrong. Try to set the encoding of the *terminal*, not the file. — bool3max, Dec 25 '19 at 21:09

@bool3max just did that and tried again with "\xE2\x82\xAC" and "\u20AC" the output is the same as before... — João Neves, Dec 25 '19 at 21:19
Out of ideas then. Try to run your executable and pipe its output to a utility such as `hexdump` or `xxd` to make sure that the correct bytes are coming out. e.g. `./yourapp | hexdump`. — bool3max, Dec 25 '19 at 21:50
Normally C outputs strings with the "C" `locale`. A first step on how to set up another `locale` for multibyte characters can be found here in https://stackoverflow.com/questions/58039815/print-utf-8-multibyte-character-in-c, but depending on your setting there might be more to it. — Jens Gustedt, Dec 25 '19 at 21:57

A simple way to do it is using the UTF-8 as native encoding. Just print like this:

#include <stdio.h>

int main()
{
    printf("\xE2\x82\xAC");

    return 0;
}
