    //  The following comments apply to SharePoint Windows classic authentication.
    //  -------------------------------------------------------------------------
    //  For example, imagine our SharePoint endpoint is https://xyzoffice.mycompany.com/
    //  The SHAREPOINT_NTLM_DOMAIN would be "mycompany.com"
    //  The SHAREPOINT_HTTPS_DOMAIN would be "xyzoffice.mycompany.com"
    //  Also, the SHAREPOINT_USERNAME would be just the name, not a full email address.
    //  for example, "chilkat" instead of "chilkat@mycompany.com"

    http = CkHttpW_Create();

    //  If SharePoint Windows classic authentication is used, then set the 
    //  Login, Password, LoginDomain, and NtlmAuth properties.
    CkHttpW_putLogin(http,L"SHAREPOINT_USERNAME");
    CkHttpW_putPassword(http,L"SHAREPOINT_PASSWORD");
    CkHttpW_putLoginDomain(http,L"SHAREPOINT_NTLM_DOMAIN");
    CkHttpW_putNtlmAuth(http,TRUE);

    //  -------------------------------------------------------------------------
    //  The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
    //  If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
    //  establish the cookie as shown at SharePoint Online Authentication
    //  -------------------------------------------------------------------------

    //  This example downloads a CSV file that is utf-8 and contains Japanese characters.

    url = L"https://SHAREPOINT_HTTPS_DOMAIN/_api/web/GetFileByServerRelativeUrl('/Documents/ChilkatTest/japanese.csv')/$value";

    CkHttpW_putAcceptCharset(http,L"utf-8");

    strCsv = CkHttpW_quickGetStr(http,url);
    if (CkHttpW_getLastMethodSuccess(http) != TRUE) {
        wprintf(L"%s\n",CkHttpW_lastErrorText(http));
        CkHttpW_Dispose(http);
        return;
    }

    //  The CSV file is contained in strCsv.
    wprintf(L"CSV:\n");
    wprintf(L"%s\n",strCsv);

    //  Note: The HTTP response hopefully indicates the charset of the response,
    //  and Chilkat should receive the string correctly.  If the response sent by
    //  SharePoint does not indicate a charset, or indicates an incorrect charset,
    //  then we can instead download the text file as binary data and interpret the
    //  bytes ourselves correctly.  For example:  

    bd = CkBinDataW_Create();
    success = CkHttpW_QuickGetBd(http,url,bd);
    if (success != TRUE) {
        wprintf(L"%s\n",CkHttpW_lastErrorText(http));
        CkHttpW_Dispose(http);
        CkBinDataW_Dispose(bd);
        return;
    }

    //  Interpret the bytes correctly as utf-8
    sb = CkStringBuilderW_Create();
    CkStringBuilderW_AppendBd(sb,bd,L"utf-8",0,0);
    wprintf(L"CSV:\n");
    wprintf(L"%s\n",CkStringBuilderW_getAsString(sb));


    CkHttpW_Dispose(http);
    CkBinDataW_Dispose(bd);
    CkStringBuilderW_Dispose(sb);
