>Yes, Librera will support old devices as long as possible
That’s real good news!

>Yes, just set use Document style (please see screenshot)
I knew it was somewhere—thanks for the heads-up!

>You can compare mupdf 1.11 vs mupdf 1.19 in the latest build (beta.librera.mobi)
Thanks for investigating this matter. It seems mupdf 1.19 gets the bold right, but fails not only on the OTF font rules but also on ligatures (like "tz" in "Hatz") now. 1.11 got the ligatures right (albeit not the Fraktur typesetting rules) but failed on the bold.

I’d love to see better OpenType support in Librera, since it is still my favourite reader, and I recommend it to others. So it seems, currently only MoonReader does things correctly, CoolReader and Librera don’t (yet).

The reason I opted for an OpenType rule set (and a standard Antiqua base text) for setting Fraktur and Kurrent fonts was:
  • Easy switching to Antiqua fonts while keeping text readable for readers that can’t read Kurrent/Fraktur. I believe in "the Reader’s Choice".
  • Easy searching within the document, using Antiqua letters.
  • Only way to have current Text-to-Speech engines speak the text correctly.

I used "LOV" type fonts LOV.HammerUnziale.otf, LOV.NeueDeutscheKurrent.otf and LOV.UnicodeFraktur.otf from ligafaktur.de for this test.

If you want to experiment with these fonts (they also work in programs like LibreOffice), here is a link to the downloadable fonts and a guide (in German).

Here are some screenshots of MoonReader, CoolReader, Librera (1.11 mupdf) and the mupdf 1.18 Android Viewer.

As you can see, the "pure" mupdf 1.18 Android Viewer (installed from here) does everything correctly, so maybe we’ll have a chance for Librera to do as well?

This is rather pleasant, and I'm happy to have a replacement for EBookDroid that uses mupdf, which always seemed to have the best performance for me. The app is very snappy (in particular the library seems able to repopulate itself very quickly). I like it.

Hm, I'm still working out exactly how to use it, but here are a few comments I came up with after the first day.
  • I'd really like to be able to read PDFs with horizontal scrolling and the screen locked to 'fit width', but it seems like this is currently impossible, as scroll mode only does vertical scrolling and book mode won't automatically lock to screen width.
  • I kind of wish I could increase the interace's font size; it's pretty small!
  • Is there a way to always have the Android system elements hidden when you start reading a book? I haven't found it yet.
  • I'd like to be able to search my library by publisher, but it doesn't seem to pick up on publisher data as specified by Calibre. In fact often it seems to miss Calibre's metadata altogether and pull messy stuff out of the file; not sure if that's a problem here or in Calibre.

Unfortunately, this is only for PDFs.

I'd really like to be able to select some text in a Epub, and highlight it with color and styles (lines, block, etc). And leave an optional notes.
