Esempio

#include <iostream>
#include <locale>
 
void try_with(const std::locale& loc)
{
    const std::messages<char>& facet = std::use_facet<std::messages<char> >(loc)
;
    std::messages<char>::catalog cat = facet.open("sed", std::cout.getloc());
    if(cat < 0 )
        std::cout << "Could not open german \"sed\" message catalog\n";
    else
        std::cout << "\"No match\" "
                  << facet.get(cat, 0, 0, "No match") << '\n'
                  << "\"Memory exhausted\" " 
                  << facet.get(cat, 0, 0, "Memory exhausted") << '\n';
    facet.close(cat);
}
int main()
{
    std::locale loc("en_US.utf8");
    std::cout.imbue(loc);
 
    try_with(std::locale(loc, new std::messages_byname<char>("de_DE.utf8")));
    try_with(std::locale(loc, new std::messages_byname<char>("fr_FR.utf8")));
    try_with(std::locale(loc, new std::messages_byname<char>("ja_JP.utf8")));
}

Possible output:
