Question

#include <stdio.h>
#include <iostream>


int main()
{
    FILE* oFile=fopen("file","wb");

    for(int i = 255; i>=0; i--)
        fprintf(oFile,"%c",i);

    system("pause");
    return 0;
}

Now, “file” contains ONLY “weird” characters:

What’s intriguing for me, using a console stream, everything is OK.

#include <stdio.h>
#include <iostream>




int main()
{


    for(int i = 255; i>=0; i--)
        printf("%c",i);

    system("pause");
    return 0;
}

The question is: why there are no “latin” characters in the output file? Even after converting from UCS-2 little endian(why it was automagically selected?) to ascii in the notepad++:

Answer 1

I think that one problem you have is that you happen to have started your file with a well known byte order mark, “feff” which is the BOM for UTF-16. This means that many editors will think this is UTF16 where they’d normally default to ASCII/UTF8.

Take a look at your file in hex:
