_wfopen and extra spaces

Im trying to write to a file with unicode but when i use _wfopen i get extra spaces between the letters like
H e l l o
instead of
Hello.
I cant figure out why.

Code:

#include <stdio.h>
#include <stddef.h>
#include <stdlib.h>
#include <wchar.h>

#define BUFFER_SIZE 50

int main(int argc, char** argv)
{
    wchar_t str[BUFFER_SIZE];
    size_t  strSize;
    FILE*   fileHandle;

    if ((fileHandle = _wfopen( L"_wfopen_test.txt",L"wt+,ccs=UNICODE")) == NULL)
    {
        wprintf(L"_wfopen failed!\n");
        return(0);
    }
    wcscpy_s(str, sizeof(str)/sizeof(wchar_t), L"Hello\n");
    strSize = wcslen(str);
    if (fwrite(str, sizeof(wchar_t), strSize, fileHandle) != strSize)
    {
        wprintf(L"fwrite failed!\n");
    }
    if (fclose(fileHandle))
    {
        wprintf(L"fclose failed!\n");
    }
    return 0;
}

What are you using to VIEW the file? If the viewer doesn't understand Unicode, it will display like this.

When you use "css=UNICODE", and the existing file has no BOM or the file is new, you get ANSI encoding when you use formatted output.

The next problem is that you are not using formatted output. fwrite() is unformatted output. It writes exactly what you tell it to (with the exception of text mode translations of \n to \r\n).

fputws(L"Hello\n", fileHandle);

I was using notepad and wordpad.
Thanks.

@Codeplug
Thank you for the explanation, its working with fputws.
