HTTPService POST with XML does not declare charset encoding

Question

Hi all.
I'm trying to do a HTTP POST of some XML using HTTPService
and I've got it working apart form the fact that the HTTP message
sent does no declare what charcater set it is using for encoding.
As a test I send a 'ñ' character and it seems from the
resultant bytes that the charset being used is UTF-8.
My ActionScript is...
var xml:XML=new XML(<root/>);
xml.@testCharacter="ñ";
xml.appendChild(<login/>);
xml.login.@username="bob";
xml.login.@password="secret";
var httpService:HTTPService=new HTTPService();
httpService.url='
http://app.localhost/null';
httpService.method="POST";
httpService.contentType=HTTPService.CONTENT_TYPE_XML;
httpService.request=xml;
httpService.send();
And what seems to get sent over the wire is (shown in
8bit-ASCII)...
POST /null HTTP/1.1
Host: app.localhost
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US;
rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7
Accept:
text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png ,*/*;q=0.5
Accept-Language: en,en-us;q=0.7,en-gb;q=0.3
Accept-Encoding: gzip,deflate
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7
Keep-Alive: 300
Connection: keep-alive
Content-type: application/xml
Content-length: 77
<root testCharacter="A±">
<login username="bob" password="secret"/>
</root>
Anyone know (1) how I can control what character set gets
used for encoding and (2) how I can get either XML or HTTPService
to declare what the encoding is?
Thanks in advance, Neil.

Jarod,
XML parser product managers who might be able to help you on a parser-specific issue like this "hang out" here on OTN in the XML forum. Have you tried posting there to catch their attention? Thanks.
