Adobe Digital Editions and Calibre might allow connection to android readers: then I'd digitize it by screenshots on my phone and, finally, OCR it with Abby Finereader.

Shoud I report the issue here asap? https://bugs.launchpad.net/calibre.

Well even easier than screenshots (should have mentioned this first), is to export the images using calibre's Edit Book: find Images folder in listing on left, right click and Select all Images files, then right click on the selection and Export all nnn files.

In my experience, usually the text is rendered in the images while XHTML gives position and actual text values for readers that let you select it (like Thorium reader). It is similar to PDFs in that respect, where text can be rendered with vector graphics and text objects are there to provide locations for highlights and dictionary lookup, etc.

So similar that I want to investigate writing a script to convert between FXL ePub and PDF. At least PDF is more popular and better supported, and there might be other cases where FXL ePub might be preferred.
