Example
Demonstrates the use of isprint() with different locales (OS-specific).
Run this code
#include <iostream>
#include <locale>
int main()
{
const wchar_t c = L'\u2122'; // trademark sign
std::locale loc1("C");
std::cout << "isprint('™', C locale) returned "
<< std::boolalpha << std::isprint(c, loc1) << '\n';
std::locale loc2("en_US.UTF-8");
std::cout << "isprint('™', Unicode locale) returned "
<< std::boolalpha << std::isprint(c, loc2) << '\n';
}
Possible output:
isprint('™', C locale) returned false
isprint('™', Unicode locale) returned true
