Hello Didier, I find this hard to understand as I am not very familiar
with LuaTeX. I do not understand why there is an error message

! Undefined control sequence.
l.1 @

and the @ sign is not followed by anything, even though the Lua code
is outputting "char" afterwards. I found that by adding an argument to
tex.sprint in the Lua code in PDFescstr in texinfo.tex, the errors
would go away. This change stopped the output from Lua being
interpreted as a control sequence. I committed this change in commit
4ec03a518. Please let me know if it works for you.
