Reading utf-8 encoded files with fopen C

I have created a text file with following characters for testing utf-8 encoding:

%gÁüijȐʨΘЋЮѦҗԘՔהڳضणணษ༒Ⴃᎃᡧᬐ⁜₪≸☺⛜⺟むヸ㒦㢒

I also have written this program in C to open file and read it:

#pragma warning(disable:4996)#include <stdio.h>#include <stdlib.h>int main() {    FILE *ptr;    ptr = fopen("inputtest.txt", "r, ccs=UTF-8");    char input[50];    if (ptr == NULL)        perror("Error opening file");    else {        if (fgets(input, 50, ptr) != NULL) {            puts(input);        }        printf(input);        fclose(ptr);    }}

If I don't use ccs=UTF-8, I will get some unreadable characters. But with it, the program crashes with code -1073740791. Also after using wchar_t and fgetws the program's output was just %.Note: I am using windows 11 and visual studio 2022 and I need to input multi-language characters.
