Re: [Dev-luatex] Very simple sample?

Another question: How can I read arbitrary TeX input? Or is this part still unfinished? Currently, LuaTeX only accepts UTF-8 input, right? But let's assume we have: \arabic{<iso arabic text>} ie, two input encodings in the same line. I don't still understand how encodings work. Javier PS. Here is a more complete example with LaTeX (or more exactly TeX inside LaTeX...): \documentclass{book} \def\lua#1{\directlua0\expandafter{\detokenize{#1}}} \def\sub#1{% \lua{ tex.print("\\subsection{#1}"); tex.print("\\message{Show a message}"); tex.print("Argument \\\#1 is #1") }} \begin{document} \lua{tex.print("\\section{Hola $\\sin a_0^2$}");} \sub{Sub section} \end{document}
