Together with Juergen Seel from
http://dorgon.proc-community.de/index.php
we did take a look at the font-problem with their dorgon-epub-ebooks.
And for the problem, that on some .epubs the reader doesnt change the font its related to a "standard-bug" of FBReader
The problem is when you got a tag of "font-family" in your styles.css
(inside your .epub - which is a .zip-file with .epub extension) then FBReader will not change the font in the view :-(
I did test this and removed the font-family -tags from the styles.css, repacked the book with Winzip and renamed it back to .epub
Now I can view the book with cover art and I can change the font, which is also viewed correctly
Juergen Seel did show me the link to the info he found at:

And the FBreader-page stated, that they didnt fully implement the CSS-Features...so FBReader could have problem with some CSS-Styles:

There are two non-implemented features that many formats required:
- support of style sheets included in the book (e.g. for HTML that would be CSS declarations)
- table support
