I've used ™ and ™ and on the initial save of the content from CE things look fine, but if I go back and resave the page all trademark symbols are converted to a "T".  If I use the "Special Characters" button provided by the editor I get the same results.  I've also set the UseHTMLEntities to false as suggested in a prior forum question.  It appears as if CE is changing the html markup from what is entered into something else that displays as a "T".  Any ideas?
