That is not going to work. And I have absolutely no idea what you thought was happening.

The KoboTouchExtended driver adds function to the built-in KoboTouch driver. It acts on books as they are sent to the device modifying the HTML code inside the books as needed and putting them on the device with the appropriate filename. If you are converting to kepub inside calibre, the extended driver is not involved. When you use calibre to send the books to the device, either driver will do the same. It will put the files on the device with the correct filenames.

And now the massive gap between S and the rest of the word has returned, but at least S renders like it does in Calibre (super big, crosses into the line below it). In koreader, the S disappears entirely.

I give up. I'm never going to be able to convert my books so the embedded fonts show properly.

What you are describing is a problem with the way the different renderers handle the code in the books. Unfortunately, they interpret the specs in different ways. And have different bugs. The epub renderer is based on Adobe RMSDK and renders the epubs very similar to ADE if you want to compare. The kepub renderer is different. The calibre viewer is different again. It works well, but is very forgiving of errors. Neither of the Kobo renderers are.

From the screenshots, what you want is doable. Attached is a screenshot from the book I have just finished (Please Don't Tell my Parents I'm a Supervillain by Richard Roberts. A fun read and I recommend it.) That's more complicated than what you have. That is a screenshot of the epub, but the kepub version is the same.

To fix this, I think we need to see the code in the book. Posting just the code from the page might be enough with the CSS. But, it would be better to see the complete book. If this is a book that is freely downloadable, post a link. Or if has no copyright it can be posted here. You can also use the ScambleEbook plugin, but that might mess up what we want to see. If you can't post it, then PM me to work out how to do it.

Also, some of the authors show up as [Last name, first name] while others show up as [First name last name]. It's driving me crazy.

Where are they showing up like this? And what do they show up in calibre as?
