I’ve been thinking about embedded fonts in eBook files. I heard it can be done with CSS, so I found this good article on embedding fonts that includes the legal issues that must be considered.
And yes, I started to use Sigil. So far I think it’s nice, but it is a tiny bit buggy. It doesn’t import files–at least not that I could see. I’m going to code my next eBook with it. More in depth review later.
