The program below counts the number of characters in a file, assuming

the file is encoded as ASCII. Modify the program so that it counts the number of characters in a file encoded as UTF-8.

#include <stdbool.h> #include <stdio.h> typedef unsigned char BYTE; int main(int argc, char *argv[]) { if (argc != 2) { printf("Usage: ./count INPUTn"); return 1; } FILE *file = fopen(argv[1], "r"); if (!file) { printf("Could not open file.n"); return 1; } int count = 0; while (true) { BYTE b; fread(&b, 1, 1, file); if (feof(file)) { break; } count++; } printf("Number of characters: %in", count);
