javascript input don't get rendered correctly in asp.net view.

I use a pie chart using google charts. In my page I load the chart as described in the docs. It's a view in asp.net that renders the output. The view checks if a class called Avstemning is populated then puts strings from that class into the chart as data. But if I use Norwegian letters like ø,æ, å. The chart data can't read it even as I specify the language option to use. What is going on here? If I change the data variable to take hard coded options with norwegian letters it works. But that's not exactly ideal. Any ideas on how to solve this?

<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>

@if (Model.Avstemning != null)
{

 <script type="text/javascript">
  google.charts
  .load('current', { 'packages': ['corechart'], 'language':'no' });
  google.charts.setOnLoadCallback(drawChart);

  function drawChart() {

    var data = google.visualization.arrayToDataTable([
        ['Avstemning', '@Model.Avstemning.Tittel'],
        ['@Model.Avstemning.Option1', @Model.Avstemning.One],
        ['@Model.Avstemning.Option2', @Model.Avstemning.Two],
        ['@Model.Avstemning.Option3', @Model.Avstemning.Three]

    ]);

    var options = {
        title: '@Model.Avstemning.Tittel'};
    var chart = new
    google.visualization.PieChart(document.getElementById('piechart'));

    chart.draw(data, options);
  }
 </script>
}

My guess is that the strings that populates the javascript code is in another format(?) so the javascript can't translate it to norwegian?
