We have started adding bootstrap markup to our sites

to add an icon we are using the following code

http://twitter.github.com/bootstrap/base-css.html#icons

Then after viewed in the JCE editor the tags are turned to tags. We also have to add   to keep the code from being stripped out.

Example of this in action:
http://joomlahosting.com/press-releases/siteground-extends-its-partnership-with-cloudflare/
(look at the bottom of the page)

Is there any way to stop this?
Is this a tinyMCE controlled value?
Any suggestions for a streamlined workflow when adding bootstrap icons?


Thanks! -- Steven
