superscript is leaving a big space between the line height.
code is
<span style="position:relative; bottom:0.2em; font-size: 0.8em">®</span>

Is there a work around. I am aware that the position:relative does not render well in outlook. What’s the other alternative to this?
I’ve made few experiments in jsFiddle and I think you will be able to use:
in firefox it does not increases the gap between the lines
