mbstowcs 함수가 이상해요.

typedef std::basic_string< wchar_t >    WSTRING;
 
int main()
{
 
    char chBuffer[1024];
    char chBuffer2[1024];
    memset(chBuffer, 0x00, sizeof(chBuffer));
    memset(chBuffer2, 0x00, sizeof(chBuffer2));
 
    setlocale(LC_CTYPE, "ko_KR.eucKR");
 
    WSTRING Msg;
    WSTRING Msg2;
 
 
    sprintf(chBuffer, "%s", "메세지");
    sprintf(chBuffer2, "%s", "message");
    int a = mbstowcs((wchar_t*)Msg.c_str(), chBuffer,1000);
    printf( "%x,%x,%x,%x\n",Msg[0], Msg[1], Msg[2], Msg[3]);
    int b = mbstowcs((wchar_t*)Msg2.c_str(), chBuffer2,1000);
 
    printf( "%x,%x,%x,%x\n",Msg[0], Msg[1], Msg[2], Msg[3]);
    printf( "%x,%x,%x,%x\n",Msg2[0], Msg2[1], Msg2[2], Msg2[3]);
 
    return 1;
