Ok, after all Paweł Fus was right on the first comment he made

Make sure your HTML file is also encoded in UTF-8. And try to use file directly from Highcharts CDN, not local files - maybe when saving file it was converted to CP1250 or something similar.


The problem was solved by saving the highcharts libs as UTF-8.

To do that I had to change the encoding of eclipse like it's said here How to change default text file encoding in Eclipse? and then I saved the .js files.

try this: overflow:"justify" for labels that are over flowing in your case.

Here is the reference: http://api.highcharts.com/highcharts#xAxis.labels

See jsFiddle
