One problem

[Zdenek Wagner]

Понимаю по руццки но отбечу по английски.

As already mentioned by Boris, the luainputenc package is for luatex,
not for pdftex. It most probably reports and error. In addition,
pdftex makes use of 8bit encodings and Type 1 fonts. I cannot
understad how it can ever work in Russian without a fontenc package.
The cmap package then cannot work. On the contrary, both luatex and
XeTeX wotk directly in Unicode and expect input in utf-8. No input
reencoding is needed. And polyglossia is beter than babel because
babel has to solve a lot of character reencoding problems while
polyglossia assumes Unicode. The cmap package is not needed in these
engine because Unicode fonts are used and character extraction is
straightforward.

Try this file, it works in both xelatex and lualatex:

\documentclass{article}
\usepackage{polyglossia}
\setdefaultlanguage{russian}
\newfontfamily\russianfont{EB Garamond}[Ligatures=TeX]
\parindent 0mm

\textbf{Отчего}

Мне грустно, потому что я тебя люблю, \\
И знаю: молодость цветущую твою \\
Не пощадит молвы коварное гоненье. \\
За каждый светлый день иль сладкое мгновенье \\
Слезами и тоской заплатишь ты судьбе. \\
Мне грустно... потому что весело тебе.
\end{document}

I have created PDF by both engines, opened PDF in okular and
copy/pasted it to kate. I got a correct text in both cases.
