Ulrike pointed out \mathitalicsmode=1 on TeX Stack Exchange, but there is still an issue with sub_mlists: %\input luaotfload.sty \font\mathfont="file:LibertinusMath-Regular.otf:mode=base;script=math" at 10pt \textfont0=\mathfont \textfont2=\mathfont \Umathcodenum`f="1D453 \protected\def\langle{\Udelimiter"4"0"27E8\relax} \protected\def\rangle{\Udelimiter"5"0"27E9\relax} \mathitalicsmode=1 $f\rangle$ \nulldelimiterspace=0pt $\left.f\right\rangle$ ${-f}\rangle$ $\left.{-f}\right\rangle$ \bye Cheers, Henri > > Cheers, Henri
