template<> class ctype_byname : public std::ctype<char>;

std::ctype_bynameのこの専門分野は、型charの文字分類機能をカプセル化します。その基本クラスstd::ctype<char>のような、汎用std::ctype_bynameとは異なり、テーブルルックアップは、文字を分類するために使用されます

Original:

This specialization of std::ctype_byname encapsulates character classification features for type char. Like its base class std::ctype<char> and unlike general-purpose std::ctype_byname, table lookup is used to classify characters

#include <iostream>
#include <locale>
 
int main()
{
    char c = '\xde'; // capital letter thorn
 
    std::locale loc("C");
 
    std::cout << "isupper('Þ', C locale) returned "
               << std::boolalpha << std::isupper(c, loc) << '\n';
 
    loc = std::locale(loc, new std::ctype_byname<char>("en_US.utf8"));
 
    std::cout << "isupper('Þ', C locale with Unicode ctype<char>) returned "
              << std::boolalpha << std::isupper(c, loc) << '\n';
