Equal Sign in URL causes problems when using ShellExecute

I typically use the following statement to launch a new instance of an Internet Explorer browser pointed to a specific URL address (strURL):

ShellExecute(Application.MainForm.Handle, 'open', 'explorer.exe', PChar(strURL), nil, SW_SHOW);

In most cases this works fine, however I have come across a case that does not work.
If the URL contains an equal sign in the URL string, the browser will not load and I get the following error message:
"The path 'test' does not exist or is not a directory. "

In the above case the particular strURL contains the following string:
strURL := 'http://www.google.com/groups?as_q=test';

It appears that the equal sign is causing the string to be divided perhaps.
I've tried substituting %3D in place of the equal sign with no success.
I would appreciate any help anyone could offer.

Thanks,

some character are not allowed. make use of this routine to solve your url problem

function URLEncode(const ASrc: string): string;
var
  i: Integer;
begin
  Result := '';
  for i := 1 to Length(ASrc) do
  begin
    if ASrc[i] = ' ' then
    begin
      Result := Result + '+';
    end else if NOT (ASrc[i] in ['A'..'Z', 'a'..'z', '0'..'9']) then
    begin
      Result := Result + '%' + IntToHex(Ord(ASrc[i]), 2);
    end else
    begin
      Result := Result + ASrc[i];
    end;
  end;
end;
