Hi Michael, After updating to newtxmath.sty version 1.60 (2019-09-27), an error
! Undefined control sequence. for \pdfglyphtounicode. occurs when we use \usepackage{newtxmath} with lualatex, platex, uplatex. These engines do not support \pdfglyphtounicode, so I think the final code of newtxmath.sty should be inside
\ifx\pdfglyphtounicode\@undefined \else ... \fi Similar issue for newpxmath.sty. Could you support those engines again? Thanks, Hironobu Yamashita
