Dear All I am getting some strange behaviour with the following minimal example via LaTeX with LuaTeX \pdfoutput=1 \documentclass[12pt]{article} \begin{document} \directlua{tex.print("{\it abc}")} \end{document} I run the above and get a PDF which displays the following text protect protect protect edef OT1OT1let enc@update I have no idea what is causing this. If I run the following using plain TeX: \pdfoutput=1 \directlua{tex.print("{\it abc}")} \bye I get a PDF which says: am itfam enit abc What am I doing wrong to cause this behaviour?
