struct french_bool : std::numpunct<char> {
    string_type do_truename() const { return "oui"; }
    string_type do_falsename() const { return "non"; }
};
 
int main()
{
    std::cout << "default locale: "

    std::cout.imbue(std::locale(std::cout.getloc(), new french_bool()));
    std::cout << "locale with modified numpunct: "

}

Вывод:

default locale: true, false
locale with modified numpunct: oui, non
