fbreader compatibility

[wandhydrant]

First, thank you a lot!

The TRPL version available today (Commit: e5ed97128302d5fa45dbac0e64426bc7649a558c (2020-08-31 17:53)) does not display on fbreader 0.12.10 (Debian 10) or Book Reader 1.12.17 (Android 10). Both can show the table of contents but the content itself is blank.

I can open it with ebook-viewer / Calibre 3.39.1 (Debian 10), though, so it must be a question of compatibility or EPUB features.

Calibre can convert the EPUB and "flatten" the file structure in the process. This helps with fbreader (though it still looks funny, with all paragraphs justified) and it looks good on Book Reader.
