XSLT conversion with MSXML does not use proper encoding

I use IXMLDOMDocument::transformNodefrom MSXML 3.0 to apply XSLT transformations. Each of the transformations has a directive xsl:outputthat defines it UTF-8as an encoding. For instance,

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
                ...
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:str="http://exslt.org/strings"
                xmlns:math="http://exslt.org/math"
                extension-element-prefixes="str math">
  <xsl:output encoding="UTF-8" indent="yes" method="xml" />
  ...
</xsl:stylesheet>

However, the converted result is always UTF-16(and the encoding attribute says UTF-16).

<?xml version="1.0" encoding="UTF-16"?>

Is this a bug in MSXML?

For various reasons, I would really like to have UTF-8. Is there a workaround? Or do I need to convert the converted result to my UTF-8own and fix the encoding attribute?

In addition to what Michael Kay (who, of course, is in place) said, here is a JScript example of how to convert to a stream using XSLT serialization in the process:

// command line args
var args = WScript.Arguments;
if (args.length != 3) {
    WScript.Echo("usage: cscript msxsl.js in.xml ss.xsl out.xml");
    WScript.Quit();
}
xmlFile = args(0);
xslFile = args(1);
resFile = args(2);

// DOM objects
var xsl = new ActiveXObject("MSXML2.DOMDOCUMENT.6.0");
var xml = xsl.cloneNode(false);

// source document
xml.validateOnParse = false;
xml.async = false;
xml.load(xmlFile);
if (xml.parseError.errorCode != 0)
    WScript.Echo ("XML Parse Error : " + xml.parseError.reason);

// stylesheet document
xsl.validateOnParse = false;
xsl.async = false;
xsl.resolveExternals = true;
//xsl.setProperty("AllowDocumentFunction", true);
//xsl.setProperty("ProhibitDTD", false);
//xsl.setProperty("AllowXsltScript", true);
xsl.load(xslFile);
if (xsl.parseError.errorCode != 0)
    WScript.Echo ("XSL Parse Error : " + xsl.parseError.reason);

// output object, a stream
var stream = WScript.createObject("ADODB.Stream");
stream.open();
stream.type = 1;
xml.transformNodeToObject( xsl, stream );
stream.saveToFile( resFile );
stream.close();

You can test using this input:

<Urmel>
    <eins>Käse</eins>
    <deux>café</deux>
    <tre>supplì</tre>
</Urmel>

And this stylesheet:

<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output encoding="UTF-8"/>
    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

I think it will be easy for you to adapt the JScript example to C ++.
