Solution 1

The version and encoding parameters must be quoted:

C++

char *xmldata = "<?xml version=\"1.0\" encoding=\"utf-8\"?>...";

The XML page cannot be displayed

The first thing to do is opening the created file with a text editor like Notepad to check if the content is as expected.

Is your application an Unicode build? Then you should use CStringA to create a single byte string or convert the string to UTF-8 (e.g. with WideCharToMultiByte()) when the string contains non-ASCII characters. If the string contains non-ASCII characters, you must convert it to UTF-8 because you specified the encoding.

Can you please tell how to convert BSTR to char *.

Jochen Arndt 17-Oct-12 9:09am

I already mentioned how to do it: Use WideCharToMultiByte().
int nSize = ::WideCharToMultiByte(CP_UTF8, 0, bstr, -1, NULL, 0, NULL, NULL);
char *lpszUtf8 = new char[nSize];
::WideCharToMultiByte(CP_UTF8, 0, bstr, -1, lpszUtf8, nSize, NULL, NULL);
// lpszUtf8 contains now the UTF-8 encoded string
// outfile << lpszUtf8;
delete [] lpszUtf8;
