Can't print cyrillics cahracters in terminal

Question

I have an labaratoly work from my university - I have to print ASCII table with ukrainian symbols, then make transliteration from ukrainian to english but I have met problems.

So, I am to print ASCII extended table in C++, it must include Ukrainian letters (cyrilics). I am on KDE neon 5.26 linux distribution, it is based on Ubuntu. Terminal is KDE's Console obiviously.

I made that code:

#include<iostream>

int main(void) {

        for (unsigned char i = 32; int(i) < 255; i++) {
                std::cout <<" [" << i << "] " << int(i) << " \t";
                if ((i-1)%5 == 0)
                        std::cout << "\n";
        }

        char ua_str[] = "Привіт";  // hello in ukrainian
        std::cout << "\n\n" << ua_str << "\n" << ua_str[4] << " is " << int(ua_str[4]) << "\n";

        return std::cout.fail() ? EXIT_FAILURE : EXIT_SUCCESS;
}

Compiled it with g++ lab3.cpp. It produces such output:

I am interested, how it printed char ua_str[] but won't print ua_str[4].

Terminal encoding is set to UTF8, I cannot find ASCII in Terminal encoding settings. If I redirect output to abc.txt text file with ./a.out > abc.txt and open it, it looks like the next:

So, I ran locale -a in terminal:

Then I ried to add std::setlocale(LC_ALL, "uk_UA.utf8"); to my program in int main(void) before the for loop but It didn't changed anything, output is the same...

I am to make transliteration script later but can't print and work properly with ukrainian letters...

So, question is: How to print and work with cyrillic cahrs in C++ on KDE neon 5.26?

I think than I have tried everething I could and it wont work. Please help me.

This is a rtf for Ukrainian Character Set KOI8-U : https://www.rfc-editor.org/rfc/rfc2319.html .... You can map your std ascii table to the required cyrillic characters. Another option is to look at something like yandex. https://yandex.com/dev/translate/ it is an api for translating but I think its a service that charges but there is usage limits or just a temporary key if not paid for. It's pretty useful for translating and an easy api.
