I'm revisiting an issue I encountered a long time ago. I now consistently use this method to handle UTF-8 encoding. It requires Windows, but it works reliably with C/C++. I'll provide the corrected source code that delivers the best results.

#include <stdio.h>
#include <stdbool.h>
#include <windows.h>

bool file_read(char name[]){
    FILE *files = NULL;
    files = fopen(name, "r");
    if(files == NULL){
        return false;
    }else{
        char Carack;
        while ((Carack = fgetc(files)) != EOF){
            printf("%c", Carack);
        }
    }
    printf("\n");
    fclose(files);
    return true;
}



int main(){

    SetConsoleOutputCP(CP_UTF8); // UTF 8 support

    file_read("d.txt");

}
