Kobo-newbie (more or less) and some font issues

After years using other eReaders (my last Kobo device was Kobo Glo) I received yesterday a Kobo Libra 2. The display is amazing – the best I've seen so far. But I quickly remembered one or two of the Kobo's shortcomings.

All my ebooks are epubs, but IIRC, the kepub-engine is a little bit more advanced and better maintained as the epub-engine (epub3?). And I like the per-chapter-infos which come with kepubs. So I prefer to kepubify the ebooks with calibre.

But, and now we come to my font problems: I have the impression that ligatures and kerning (still?) are a problem with kepubs, or is it just me? And fonts in gerneral seem to be problematic. I like the fonts Literata and Bookerly very much. But, with Literata I get very big line spaces and no kerning and no ligatures at all. With Bookery, I'm not sure about kerning/ligatures, but italic text is always displayed as bold-italic.

So, maybe you can bring me up to date:
- Are kerning and ligatures still not supported within the kepub-engine?

- Why is the line spacing (only) with Litarata so huge? I took the static fonts (Literata-Regular.ttf, Literata-Italic.ttf, Literata-BoldItalic.ttf, Literata-Bold.ttf) out from the font package. But there are other variants (Literata_18pt, Literata_24pt, Literata_36pt, …).

- Using Bookerly: Why is italic displayed as bold-italic? Am I doing something wrong with fonts import? I put the files Bookerly-Regular.ttf, Bookerly-Bold.ttf, Bookerly-BoldItalic.ttf and Bookerly-Italic.ttf in the fonts-directory. Is the naming wrong?

- I applied some patches ("My 10 line spacing values", "Set KePub hyphenation", "Unify font sizes"). Maybe I missed a useful patch that would help here?

I have attached two photos: One showing Bookery with (wrong) bold-italic text and one showing Literata with the big line space and no ligatures etc.
