Variant BSTR are not pointers to char. But pointers to specially
allocated Unicode Strings.
VARIANT v;
v.vt 	  = VT_BSTR;
v.bstrVal = SysAllocString(L"toto");

Easier is to use the MFC supplied Variant wrapper, even including
automatic conversions from CString to and from Variant, and double,
int, DATE...
