Troubles with listings and polish characters (lualatex)

Question

How I can display properly polish characters in code of programming language using listings package and lualatex compiler?

main.cpp:

//Zażółć gęślą jaźń
#include <iostream>
int main() {
  std::cout << "Hello World!\n";
  return 0;
}

main.tex:

\documentclass[12pt, a4paper]{article}
\usepackage[polish]{babel}
\babelprovide[transforms = oneletter.nobreak]{polish}
\usepackage{listings}
\usepackage{xcolor}
\definecolor{codegreen}{rgb}{0,0.6,0}
\definecolor{codegray}{rgb}{0.5,0.5,0.5}
\definecolor{codepurple}{rgb}{0.58,0,0.82}
\definecolor{backcolour}{rgb}{0.95,0.95,0.92}
\lstdefinestyle{mystyle}{
    backgroundcolor=\color{backcolour},

    commentstyle=\color{codegreen},
    keywordstyle=\color{magenta},
    numberstyle=\tiny\color{codegray},
    stringstyle=\color{codepurple},
    basicstyle=\ttfamily\footnotesize,
    breakatwhitespace=false,

    breaklines=true,

    captionpos=b,

    keepspaces=true,

    numbers=left,

    numbersep=5pt,

    showspaces=false,

    showstringspaces=false,
    showtabs=false,

    extendedchars=true, 
    tabsize=2
}
\lstset{style=mystyle}
\hbadness=99999
\begin{document}
\lstinputlisting[language=C++]{main.cpp}
\end{document}

First result (lualatex):

My goal is to have the result, as the picture below (in lualatex compile):

Many thanks in advance!

@UlrikeFischer Fact! Now, after that suggestion, I have something like this: link to current result — constantin_d, Jul 30 '22 at 21:49
Actually the oneletter.nobreak feature requires lualatex typography - one-letter word at the end of line - TeX - LaTeX Stack Exchange -- removing that features it works with pdflatex. — user202729, Jul 31 '22 at 05:13
Suggestion: Edit your question to adjust for omitting fontenc with LuaLatex AND your screenshot (i.e. resolve the link, as it may vanish over time). — MS-SPO, Jul 31 '22 at 09:08
@MS-SPO Sorry, but I don't understand You... I must remove a fontenc ? — constantin_d, Jul 31 '22 at 11:27
@MS-SPO Hmm... I removed in my code, but I understand, that I must do also in a question version? — constantin_d, Jul 31 '22 at 11:59
It's a suggestion. If you follow our approach, that 1 question = 1 problem, and each answer = 1 solution, and take into account that relevant information might get lost in a chain of comments ... it's natural to add what's relevant. Makes problems/questions more efficient to re-use by other people: all relevant infos in one place (only). — MS-SPO, Jul 31 '22 at 12:04
@MS-SPO Aaa... okeeey... I got it... I will try do this in a future. Thanks, and sorry for a trouble... — constantin_d, Jul 31 '22 at 12:07

A few bugs here.

In pdflatex the transforms = oneletter.nobreak babel option is not supported. So you must use lualatex (or remove that feature)
In lualatex do not use fontenc or inputenc. (by the way you don't have to use inputenc in newer versions Is there any reason to use inputenc?) In this particular case you must remove fontenc for it to work. (alternatively add both fontenc and literate works, but why bother?)
listings has some bugs that doesn't allow it to handle characters with codepoint > 255. This half of the question is duplicate of https://tex.stackexchange.com/a/25396/250119. Use the fix there

Seems to work for me.

(as you can probably infer, include every character with codepoint > 255 once in addition to the existing. You can also use the ^^^^<4 digits> or ^^^^^^<6 digits> notation to specify by hex code.)

Ouch... I understand... thanks a lot! By the way, I added big letters to Your code, and it works perfectly! — constantin_d, Jul 31 '22 at 06:31

Just for comparison. What we can do with OpTeX:

\fontfam[lm]
\hsize=10cm
\noindent
Przetestujmy możliwości języka C++, oraz wiszące litery na końcu zdania i coś tam jeszcze:
\verbinput \hisyntax{C} (-) main.cpp
\bye

The result:

Wow, that's so cool! – constantin_d Jul 31 '22 at 06:47

Suggestion: Please Edit this solution and explain it a little bit more, at least what you mean by OpTex. Not everybody is familiar with it, and some more context won't hurt. – MS-SPO Jul 31 '22 at 09:10
@MS-SPO Fact, I didn't use it earlier... (I mean OpTeX) – constantin_d Jul 31 '22 at 11:44
