So far I have only made epub's for myself (from books I bought as pdf, or scanned a few), and then I only cared that it looked ok for me.
But this is a little project where I'm digitalizing a very, very rare book from 1887 and I plan to share (for free) with my peers within a profession. So it has to work for other e-readers (and iPad/Android) besides my own.
This is a massive learning moment for me. I test things much more now, and I must say I'm very surprised how much of the epub-specification most software doesn't support.

The first character in the first word in most chapters are a very special font. I have been playing around with making my own font, or buy a very similar one, but now I'm not sure if it's worth it due to all these embedded font-challenges.
For special characters, the ballot box is the only one I noticed so far. There may be more.
Thanks for the tip on svg for the characters, that seems to be the easiest and probably most supported way to do it. (I'll probably play around with fonts just for fun though...
).

This place is fantastic! I learn much, much more here compared to from the epub-books I have bought. Thanks again!
