how to not have a default font

Hi,

I have installed fckeditor through a rails application. i'm using the toobar without font (the most basic toobar.. ). When i write a article and store it to the database , i see that i have stored arial font , even if i don't choose a font. I know that arial is the default font, but what i would like is to not have default font.
if i just write blabla trought the fckeditor, i just want to store blabla.

What i have found in the forum in how to replace the defaut font, but what i need is to not have a default font :shock:

thanks in advance for your help.
