Pretty print if/else/elseif chains nicer, like this: 

void printutf8(unsigned int X) {
  if (X <= 127)
    printf("%c", (char)X);
  else if (X <= 2047)
    printf("%d %d ", 128 + 64 + (X >> 6), 128 + (X & ((1 << 6) - 1)));
  else if (X <= 65535)
    printf("%c%c%c", 128 + 64 + 32 + (X >> 12), 128 + ((X >> 6) & 63), 128 + (X & 63));
  else
    printf("UNKNOWN %d\n", X);

instead of:

  if (X <= 127)
    printf("%c", (char)X);
  else
    if (X <= 2047)
      printf("%d %d ", 128 + 64 + (X >> 6), 128 + (X & ((1 << 6) - 1)));
    else
      if (X <= 65535)
        printf("%c%c%c", 128 + 64 + 32 + (X >> 12), 128 + ((X >> 6) & 63), 128 + (X & 63));
      else
        printf("UNKNOWN %d\n", X);
