Original:

Constructs a copy of other except for the facet of type Facet (typically deduced from the type of the argument) which is installed from the argument facet. If facet is NULL, the constructed locale is a full copy of other. The locale constructed in this manner has no name.

Esempio

#include <iostream>
#include <locale>
#include <codecvt>

int main()
{
    std::locale l1;  // l1 is a copy of the classic "C" locale
    std::locale l2("en_US.UTF-8"); // l2 is a unicode locale
    std::locale l3(l1, l2, std::locale::ctype); // l3 is "C" except for ctype, which is unicode
    std::locale l4(l1, new std::codecvt_utf8<wchar_t>); // l4 is "C" except for codecvt
    std::cout << "Locale names:\nl1: " << l1.name() << "\nl2: " << l2.name()
               << "\nl3: " << l3.name() << "\nl4: " << l4.name() << '\n';
