Get rid of automatic hyphenation?

RH8 inserts a magic hyphen into some words, and this hyphen is not visible in the RH8 editing window nor on the final output UNLESS I happen to scale the window to such a size that the words needs to split itself. I can see the hypen in HTML Editing mode. I do NOT want RH8 to put the special hypen into my words EVER. I want the words to NEVER have the magic character. How can I turn this off?
