CT2A这个宏的正确用法：

其实主要用的是：CW2A ==== 宽字符转单字节

BOOL SetItemStringAttribute(UINT uItemID, LPCSTR lpszAttrib, LPCTSTR lpszValue)
    {
        return SetItemAttribute(uItemID, lpszAttrib, CT2A(lpszValue, CP_UTF8));
    }

tinyxml.h中常有字符串转换 atlconv.h // =========================================================
