      [edit]Example

      Demonstrates the use ofstd::isspace() with different locales (OS-specific).

      Run this code
      #include <iostream>#include <locale> void try_with(wchar_t c,constchar* loc){std::wcout<<"isspace('"<< c<<"', locale(\""<< loc<<"\")) returned "<<std::boolalpha<<std::isspace(c,std::locale(loc))<<'\n';} int main(){constwchar_t EM_SPACE= L'\u2003';// Unicode character 'EM SPACE'    try_with(EM_SPACE,"C");    try_with(EM_SPACE,"en_US.UTF8");}

      Possible output:

      isspace(' ', locale("C")) returned falseisspace(' ', locale("en_US.UTF8")) returned true
