What is the code the you are using ?

Here is the right way to do that:
http://delphi.about.com/od/adptips2005/qt/webbrowserhtml.htm

uses mshtml;

var
    iall : IHTMLElement;
begin
   if Assigned(WebBrowser1.Document) then
   begin
     iall := (WebBrowser1.Document AS IHTMLDocument2).body;

     while iall.parentElement <> nil do
     begin
       iall := iall.parentElement;
     end;
     memo1.Text := iall.outerHTML;
   end;
end;

Open in new window

I have made simple test on new project.
WebBrowser navigates prepared html file, and show it in tmemo.
Code is like jimyX: described.
And unfortunately i still have ????? in memo.

There is nothing  i could do wrong.

html file that i have loaded have charset=utf-8 and characters iam wrote  was cyrillic.

Set your memo font to "Arial Unicode MS".

That works if you write directly on the memo from the keyboard (I tried Chinese on my PC which is not configured to Chinese language and it worked).

Anyway let's get the string decoded using UTF8Decode:
memo1.Text := UTF8Decode(iall.outerHTML);
or,
memo1.Text := Utf8ToAnsi(iall.outerHTML);

If also not working (and that's because Delphi 7 default components do not support Unicode/UTF-8) you have to use another components that support Unicode, such as:
