Adding UTF encoding to JS XML object

[f_atencia]

Say I have the following XML variable:

var oResult = Server.CreateObject("MSXML2.DOMDocument.4.0");
    oResult.async = false;
    oResult.setProperty("ServerHTTPRequest", true);

How do I get the encoding to display in the header section? For example:

<?xml version="1.0" encoding="UTF-8"?>

when I run it in the browser?

Any help will be greatly appreciated.
