How to encode HTTP response body as UTF-8 in node.js

This is currently all the node.js server code:

require('http').createServer(function (req, resp) {
    var html = [
        '<!DOCTYPE html>',
        '<html>',
            '<head>',
                '<meta charset="utf-8" />',
                '<title>Sample Response</title>',
            '</head>',
            '<body>',
                '<p>Hello world</p>',
            '</body>',
        '</html>'
    ].join('');

    resp.writeHead(200, {
        'Content-Length': Buffer.byteLength(html, 'utf8'),
        'Content-Type': 'application/xhtml+xml;'
    });
    resp.write(html, 'utf8');
    resp.end();
}).listen(80);

Based on my understanding of the node.js documentation, the second argument to 'utf8' for resp.write () should force node to encode the html string as UTF-8, and not UTF-16, which JavaScript strings are originally represented as. However, when I point my browser to localhost: 80, look at the source code and save it in a local html file, Notepad ++ tells me that the file is encoded in UTF-16. In addition, when I run it through the W3C HTML code checker, he also complains about "The declaration of the internal encoding utf-8 is not consistent with the actual encoding of the document (utf-16)."

I did not believe them when they said that IE is a terrible browser. I think we all need to learn some time :(
