xml-js package converting xml string (not file) to js scrambles utf-8 charcaters

Question

Using npm package xml-js I tried to convert some xml string with utf-8 characters in it. The method xml2js(..) is used. It scrmabled utf-8 characters like german umlaut chracters. Please take a look at the bellow example and consequent result:

var convert = require('xml-js');
var xml =
'<?xml version="1.0" encoding="utf-8"?>' +
'<note importance="high" logged="true">' +
'    <title>Deutsche TODOs</title>' +
'    <todo>Ihr seid schön!</todo>' +
'    <todo>Schönen abend sagen zur meine Frau!</todo>' +
'</note>';
var result1 = convert.xml2json(xml, {compact: true, spaces: 4});
console.log(result1, '\n', result1);

Result1 It simply scrambles the text with umlauts inside the <todo> tags:

 {
    "_declaration": {
        "_attributes": {
            "version": "1.0",
            "encoding": "utf-8"
        }
    },
    "note": {
        "_attributes": {
            "importance": "high",
            "logged": "true"
        },
        "title": {
            "_text": "Deutsche TODOs"
        },
        "todo": [
            {
                "_text": "Ihr seid schön!"
            },
            {
                "_text": "Schönen abend sagen zur meine Frau!"
            }
        ]
    }
}

EDIT: The original text that I was running into trouble with has been given in the link below in the runkit link:

The problem is it's not reproduceable in the runkit app but in my app on the powershell console, the scrambledtext is showing all the time even though I have updated from version [email protected] to [email protected].

Got any solution for this?
