Hi,
the following gives different results in luatex and pdftex: while the
right margin kern will not be reported by pdftex because of the fil in
parfillskip, luatex will show it nonetheless. Is this expected?
(A real-world example is this:
https://github.com/schlcht/microtype/issues/57)
\ifx\directlua\undefined
\pdfprotrudechars2
\else
\protrudechars2
\fi
\lpcode\font`(=500
\rpcode\font`)=500
\parindent0pt
%\parfillskip0pt
\showboxbreadth99
\setbox0\vbox{( )}
\setbox0\vbox{\unvbox0 \setbox0\lastbox \showbox0
\message{L: \leftmarginkern0^^JR: \rightmarginkern0^^J}}
\bye
Bye,
--
Robert
