scanf and strlen rely on '\0' to indicate string termination, but I don't think
this goes well with unicode strings.

I believe the right way to do something similar (without buffer length) is
this:

#include <stdio.h>
#include <fcntl.h>
#include <io.h>

int main( void )
{
    wchar_t buf[1024];

    _setmode( _fileno( stdin ), _O_U16TEXT );
    _setmode( _fileno( stdout ), _O_U16TEXT );

    wscanf( L"%ls", buf );
    wprintf( L"%s", buf );

}

HTH,
Thanks.
