Hi,
luatex doesn't deal with negative protrusion values correctly -- for
opentype fonts, the margin kern is too small, while for type1 fonts it's
way off, and even in the wrong direction:
\tracingoutput1
\showboxbreadth\maxdimen
\showboxdepth\maxdimen
% Opentype:
\input{luaotfload.sty}
\font\x="Latin Modern Roman" at 12pt
% Type1:
% \font\x=cmr12
\x
\pdfprotrudechars2
\parindent=0pt
\lpcode\x`N=-500 \rpcode\x`N=-500
\lpcode\x`Z= 500 \rpcode\x`Z= 500
H\hfill H\penalty-10000 N\hfill N\par
H\hfill H\penalty-10000 Z\hfill Z\par
\bye
Regards,
