多字节MFC工程下char*转CString乱码的研究

int lengthOfWcs1 = MultiByteToWideChar( CP_UTF8, 0, szBuff, -1, NULL, 0 );
wchar_t* wcs1 = new wchar_t[lengthOfWcs1 + 1];
MultiByteToWideChar( CP_UTF8, 0, szBuff, -1, wcs1, lengthOfWcs1 );

int lengthOfWcs2 = WideCharToMultiByte(CP_ACP,NULL,wcs1,-1,NULL,0,NULL,FALSE);
char * wcs2 = new char [lengthOfWcs2 + 1];
WideCharToMultiByte( CP_OEMCP,NULL,wcs1,-1,wcs2,lengthOfWcs2,NULL,FALSE);

outputStr.Format("%s",wcs2);

delete wcs1;
wcs1 = NULL;

delete wcs2;
wcs2 = NULL;
