Hyphenation CSS

[SofieD]

Hello,

I am sort of new to Freda but I've been working with e-books for a while. My native language is Dutch and often, hyphenation isn't the best as not every reader/software supports Dutch. Now, I usually turn off hyphenation alltogether so the readers won't have to deal with wrong hyphenation. 

I include the following code in the CSS:

 -epub-hyphens: none;
  -webkit-hyphens: none;
  -ms-hyphens: none;
  hyphens: none;
  adobe-hyphenate: none;

This turns off hyphenation in about everything except Freda. 

What code do I need to turn it off in the Freda reader?

Thank you in advance!
