You need the the wysiwyg_filter module.

Though the FAQ is confusing or wrong in this regard... the answer was close by. There was a link highlighted in pink with strike-through, "Tiny MCE and Filter HTML not allowing font changes." The answer to your is question is thus at:

Looking at the post-times, I see that it is possible that you are @tjtj. Arggh, I wish this list were on g.d.o. Anyway, please write back to this list if you get your question answered in a different place so people don't waste their time helping someone who got help elsewhere.

In Drupal 7 using Tiny MCE and Wysiwyg, it seems impossible to get font changes if you filter the HTML. The post in the FAQ (http://drupal.org/node/417166#filter-styles) does not work. I always get a <span> entry in my text irrespective of whether the "Convert <font> tags to styles" check box is checked. So how can I specify the HTML filter so that it is smart enough to allow font changes?

Thanks, Jim Rome
