Ok, this is my workflow:
- I open an epub
- I place a font-family entry in the stylesheet
- I add via "Import files into booK" the font file
- As the font file is not placed in the fonts/ dir, and no fonts.css is created, I manually add the @font-face entry in the stylesheet.
Using the "Embed referenced fonts" does not find anything, but I can understand that as the font I want to use is not located in the windows fonts dir.
@DiapDealer: Hmm, Did not used "New file (images/fonts/HTML/etc." before, but yes, that could also be an option.
