add more html tag support
We're trying to add some superscripted text to chart subtitles, but the <sup> tag is not supported. Can you add support for some more html tag support for tags like <sup> and <sub>

Actually Unicode has a separate character for squared: http://jsfiddle.net/h37VJ/

You are aware that you can use true HTML? http://jsfiddle.net/highcharts/nHfcb/2/

This would be helpful as our our charts frequently display data for which we want to indicate the "R-squared" which we typically write as "R<sup>2</sup>". Workarounds like using a <span> with CSS to try to re-create the <sup> tags doesn't work because nothing we do can raise the 2 off of the bottom vertical (as can be seen here: http://jsfiddle.net/nHfcb/1/ ).
