Hi Georg,
thank you very much for this insight. I really like the EB Garamond.
It's a wonderful typeface for reading. I used it to typeset books with
more than 500 pages together with lualatex and the selnolig package
which produced good results with no effort.
I was disappointed to learn that there is no package like selnolig for
ConTeXt but the book I am now typesetting is only 120 pages long and
I'll switch ligatures off manually with the ZWNJ replacement. (The
ConTeXt notation is a bit uncomfortable, but as I only have to use it
once...)
I only found one issue with ZWNJ. It splits up the words so that they
are not found by the search.
If ZWNJ is the right way to do it, I'll start a tiny project on Github
with a replacement file.
First time I hear about the new keyboard layout. I think I want my T2
keyboard now! ;-)
