At least part of the solution was to switch in the CSV Editor the encodings a couple of times and then at the end back to UTF8. And then it worked.

However, the special characters in the title of the axis appear only ok when using ISO Latin 1. Otherwise, still awkward characters.


I was having difficulties to print special characters in the Highcharts. This is how i resolve the issue. Set 'useHTML' to true to print the special characters in the title. I thought it may be helpful to someone who come to this page. title: { useHTML: true, text: 'Monthly – Temperature' },


You should have utf-8 encoding in all files.

var chart = new Highcharts.Chart({
    chart: {
        renderTo: 'container'
    xAxis: {
        categories: ['ä', 'ä']
    series: [{
        data: [29, 71]        

Works well.
