std::ispunct(std::locale)(3)

NAME
std::ispunct(std::locale) - std::ispunct(std::locale)

Synopsis
   Defined in header <locale>
   template< class CharT >
   bool ispunct( CharT ch, const locale& loc );
   Checks if the given character is classified as a punctuation character by the given
   locale's std::ctype facet.

Parameters
   ch - character
   loc - locale

Return value
   Returns true if the character is classified as punctuation, false otherwise.

Possible implementation
   template<class CharT>
   bool ispunct(CharT ch, const std::locale& loc)
   {
       return std::use_facet<std::ctype<CharT>>(loc).is(std::ctype_base::punct, ch);
   }

Example
   Demonstrates the use of std::ispunct() with different locales (OS-specific). // Run this code
 #include <iostream>
 #include <locale>
 int main()
 {
     const wchar_t c = L'\u214b'; // upside-down ampersand
     std::locale loc1("C");
     std::cout << "ispunct('⅋', C locale) returned "
               << std::boolalpha << std::ispunct(c, loc1) << '\n';
     std::locale loc2("en_US.UTF-8");
     std::cout << "ispunct('⅋', Unicode locale) returned "
               << std::boolalpha << std::ispunct(c, loc2) << '\n';
 }

Possible output:
 isalpha('⅋', C locale) returned false
 isalpha('⅋', Unicode locale) returned true
