Node.js Output Variation Between console.log() and response.write()?

I have the following Node.js Code that displays the plain text content of a file of installed NPM Modules on both the console and the resulting web page:

var flargs = process.argv.slice(1);
var flnm = flargs[1]
//  Continue With This
flsys.readFile(flnm, {encoding: "utf8"}, function read(err, data) {
    if (err) {
        throw err;
    }
fltxt = data;
console.log(fltxt);  // Print Contents of File To Shell Display
});

var server = http.createServer(function (req, res) {
    res.statusCode = 200;
    res.setHeader('Content-type', 'text/plain');
    res.write(fltxt);
    res.end();
});

server.listen(port);
console.log('Server Started on Port #: ' + port);
console.log('Argument: ' + flnm);

The console.log command displays the proper text output. The HTTP Response Objects Encodes the Line Output Differently ... Sample Output on the Browser:

How Can I resolve the encoding difference on the Browser Text Output?
