How to tell if text on the windows clipboard is ISO 8859 or UTF-8 in C++?

Question

I would like to know if there is an easy way to detect if the text on the clipboard is in ISO 8859 or UTF-8 ?

Here is my current code:

    COleDataObject  obj;

    if (obj.AttachClipboard())
    {
        if (obj.IsDataAvailable(CF_TEXT))
        {
            HGLOBAL hmem = obj.GetGlobalData(CF_TEXT);
            CMemFile sf((BYTE*) ::GlobalLock(hmem),(UINT) ::GlobalSize(hmem));
            CString buffer;

            LPSTR str = buffer.GetBufferSetLength((int)::GlobalSize(hmem));
            sf.Read(str,(UINT) ::GlobalSize(hmem));
            ::GlobalUnlock(hmem);

            //this is my string class
            s->SetEncoding(ENCODING_8BIT);
            s->SetString(buffer);
        }
    }
}

Check out the definition of CF_LOCALE at this Microsoft page. It tells you the locale of the text in the clipboard. Better yet, if you use CF_UNICODETEXT instead, Windows will convert to UTF-16 for you.
