[luatex] Cyrillic in \directlua0

So, it works:
--------------------
\documentclass{article}
\usepackage[T2A]{fontenc}
\usepackage[utf8]{luainputenc}
\usepackage{luatextra}
\input cyracc.def
\font\tencyr=wncyr10
\def\cyr{\tencyr\cyracc}
\def\T2A{}
\begin{document}
Здравствуй, Мир

\directlua0{
tex.print([[Здравствуй, Мир]])
}
\end{document}
--------------------

But as I rightly understand, it used very old method for cyrillic language.

That works too.

So, i use pdfLaTeX with T2A  in fontenc and utf8 inputenc much for new
documents in russian and english (without any languages). But there
are some problems in this case, for example listings package works
uncorrectly with utf-8 coded source. Also, i am trying to use python
inside latex (for some automatisation), but i think, that use lua in
lualatex is better.
