Delphi: CDO.Message encoding problems - delphi

Question

We wrote a Delphi program that send some informations with CDO.
In my Win7 machine (hungarian) the accents are working fine.
So if I sent a mail with "ÁÉÍÓÖŐÚÜŰ", I got it in this format.
I used iso-8859-2 encoding in the body, and this encode the subject, and the email addresses to (the sender address is contains name).
I thought that I finished with this.
But when I try to send a mail from a Win2k3 english machine (the mailing server is same!), the result is truncate some accents:
Ű = U
Ő = O
Next I tried to use UTF-8 encoding here.
This provided accents - but wrong accents.
The mail contains accents with ^ signs.
ê <> é
This is not valid hungarian letter... :-(
So I want to know, how to I convert or setup the input to I got good result.
I tried to log the body to see is changes...
Log(SBody);
Msg.Body := SBody;
Log(Msg.Body);
... or not.
But these logs are providing good result, the input is good.
So it is possible lost and misconverted on CDO generate the message.
May I can help the CDO if I can encode the ANSI text into real UTF.
But in Delphi converter functions don't have "CodePage" parameters.
In Python I can said:
s.encode('iso-8859-2')
or
s.decode('iso-8859-2')
But in Delphi I don't see this parameter.
Is anybody knows, how to preserve the accents, how to convert the accented hungarian strings to preserve them accented format?
And I want to know, can I check the result without sending the mail?
Thanks for your help:

a quick google search with "delphi string codepage" got me to torry's delphi pages
and maybe the following codesnippets (found here) can shed some light on your problem:
{:Converts Unicode string to Ansi string using specified code page.
#param ws Unicode string.
#param codePage Code page to be used in conversion.
#returns Converted ansi string.
}
function WideStringToString(const ws: WideString; codePage: Word): AnsiString;
var
l: integer;
begin
if ws = ' then
Result := '
else
begin
l := WideCharToMultiByte(codePage,
WC_COMPOSITECHECK or WC_DISCARDNS or WC_SEPCHARS or WC_DEFAULTCHAR,
#ws[1], - 1, nil, 0, nil, nil);
SetLength(Result, l - 1);
if l > 1 then
WideCharToMultiByte(codePage,
WC_COMPOSITECHECK or WC_DISCARDNS or WC_SEPCHARS or WC_DEFAULTCHAR,
#ws[1], - 1, #Result[1], l - 1, nil, nil);
end;
end; { WideStringToString }
{:Converts Ansi string to Unicode string using specified code page.
#param s Ansi string.
#param codePage Code page to be used in conversion.
#returns Converted wide string.
}
function StringToWideString(const s: AnsiString; codePage: Word): WideString;
var
l: integer;
begin
if s = ' then
Result := '
else
begin
l := MultiByteToWideChar(codePage, MB_PRECOMPOSED, PChar(#s[1]), - 1, nil, 0);
SetLength(Result, l - 1);
if l > 1 then
MultiByteToWideChar(CodePage, MB_PRECOMPOSED, PChar(#s[1]),
- 1, PWideChar(#Result[1]), l - 1);
end;
end; { StringToWideString }
