convert unicode codepoint to character

[gstercken]

How do I convert a unicode code point into a UTF-16 encoded string in Visual C++ 6?

You can simply insert the 16-bit hexadecimal codes into a UNICODE string literal by escaping them with "\x" (provided that your project is built for UNICODE):

LPCTSTR str = _T("Some text: \x00C4\x00D6\x00DC");
