Same problem myself, but try the below (( if it makes any sense )).
Taken from the advice I got from a previous post that got cut off.
but you should be able to post into Notepad, which will remove the additional character formatting, or you can even use notepad++ and switch the encoding back and forth (utf-8 > ansi iso > utf-8 etc) That way you can edit in word, paste to notepad, and then paste here.
One Character thread deleted also.
