[Question] Use HTML for labels. Fontello is supported?

Hi!
I comented in the closed issue and don’t know if its visible now. #401. (This issue was created for the version 1.0.2)

It’s possible use HTML for labels in the new version 2.1.4??
I need use “fontello”.
I have to do something like this:
return "<i class='icon-ok-circled2'></i>" + chart.data.labels[tooltipItem[0].index];

Thank you so much for everything
