Comment (by lisota):

 A fix for this is needed. icon fonts routinely use empty elements with a
 class defined. Font Awesome uses the <i> tag. Icomoon likes to use <span>.

 I don't buy that this is plugin material. This is TinyMCE being too
 opinionated and aggressive on what it decides to remove from HTML. These
 are common use cases with the rise in use of icon fonts.
