Sorry, if you don't mind, can you try another program?

#include <windows.h>
#include <stdio.h>
#include <stdlib.h>

void count(LPCWSTR w, int size)
{
    char *buf;

    int i, ret;

    ret = WideCharToMultiByte(
        CP_ACP,
        0,
        w,
        size,
        NULL,
        0,
        NULL,
        NULL
    );

    if (ret == 0)
    {
        printf("error\n");

        return;
    }

    printf("required = %d, ", ret);

    buf = (char*)malloc(ret);

    ret = WideCharToMultiByte(
        CP_ACP,
        0,
        w,
        size,
        buf,
        ret,
        NULL,
        NULL
    );

    printf("written = %d\n", ret);

    for (i = 0; i < ret; ++i)
    {
        printf("%d ", (int)buf[i]);
    }

    printf("\n");

    free(buf);
}

int main()
{
    count(L"encode me", 9);
    count(L"encode me", 10);
}

required = 9, written = 9
101 110 99 111 100 101 32 109 101
required = 10, written = 10

On Windows, "required buffer size" equals to "written size"
and I thought this is always true. But I noticed that there
is not such statements in MSDN document.

Maybe on xbox, "required buffer size" is more than really
required size like this...
