My bad, I wasn't precise enough. The *layout* engine doesn't do complex layout
, even though it theoretically could in the case of the one used for KF8 files (FT+FC+Pango+Cairo).
EDIT: That's not entirely accurate, see Doitsu's original post, and my adventures below.
TL;DR: On a vanilla Kindle, Code2000 does complex layouts, but not Publisher Fonts.
On a hacked Kindle, it gets complicated, but you might be able to get away with complex layouts with a custom font.
So, yeah, it should mostly behave like a K3 on FW 3.4, with a wider unicode coverage, and possibly slightly less/different issues
.
Fontconfig settings aren't usually terribly readable to begin with, but it's especially messy on the Kindle, so don't necessarily expect that what you see is what you'll actually get
.
