Need a delphi sample code.

Question

Can you make a Delphi sample code using the following?
​
httpReq:= CreateOleObject('WinHttp.WinHttpRequest.5.1');
​
I keep getting an error message.
"No mapping for the Unicode character exists in the target multi-byte code page."
My delphi  is 10.4.
​
Thanks.

[Here is my code]

httpReq:= CreateOleObject('WinHttp.WinHttpRequest.5.1');
    hr:= httpReq.Open('post','https://xf-english-dictionary1.p.rapidapi.com/v1/dictionary', false);
    httpReq.setRequestheader('content-type','application/json');
    httpReq.setRequestheader('X-RapidAPI-Host','xf-english-dictionary1.p.rapidapi.com');
    httpReq.setRequestheader('X-RapidAPI-Key','xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx');

str1 := '{"selection":"successfully"';
    str2:= ',"textAfterSelection" : "completed their project."';
    str3:= ',"textBeforeSelection" : "They"}';

str := str1+str2+str3;
    if hr= S_OK then HttpReq.Send(str);

If HttpReq.Status = 200 Then begin
       showmessage(HttpReq.responsetext);
    end;
