std::cout << "Length: " << str.size() << '\n';
std::cout << "Character at index 11: " << str[11] << '\n';
std::cout << str << '\n';
size_t pos = str.find("😎");
if (pos != std::string::npos) {

}
std::cout << "Is symbol? `" << str.at(11) << "` " << (str.is_symbol(11)? "YES\n" : "NO\n");
std::cout << "Is uppercase? `" << "Ц " << (utf8::is_uppercase("И")? "YES\n" : "NO\n");
