I have a code that generates charts dynamically based on the users inputs. I do not specifically format the tooltip, I just allow the defaults to take control. For some reason, there is consistently an a with a hat over it in the tooltip. For example, when hovering over a column chart entry, the tooltip shows:

Category a(hat)- Series name:Value

Any idea where this ahat is coming into play?

  • Looks like an "unprintable character" - could you dump the string you created as hex bytes to see what is in it? I suspect some Unicode crept on. – Floris Jun 24 '14 at 05:49
  • I don't actually create the string, it is done through some default method. – Joshua Foxworth Jun 24 '14 at 06:30
  • Can you get to the string and print it as hex bytes? – Floris Jun 24 '14 at 06:45

  • This is not a duplicate. I understand the encoding issue, what I need to know is where Highcharts is introducing this mistake as I am using all default settings and not formatting the tooltip myself. – Joshua Foxworth Jun 24 '14 at 12:55
  • Just read my answer.. it's introduced in default `pointFormat`. – Paweł Fus Jun 27 '14 at 13:08
  • Thanks Pawel Fus for the answer. Is there a way to close this question or have you answer it so that I can select that answer without causing a problem? – Joshua Foxworth Jul 01 '14 at 05:23
  • I won't because it's duplicate and answer would be the same. – Paweł Fus Jul 15 '14 at 13:33
