Demonstrates the use of isblank() with different locales (OS-specific).

#include #include   void try_with(wchar_t c, const char* loc) { std::wcout << "isblank('" << c << "', locale("" << loc << "")) returned " << std::boolalpha << std::isblank(c, std::locale(loc)) << '\n'; }   int main() { const wchar_t IDEO_SPACE = L'\u3000'; // Unicode character 'IDEOGRAPHIC SPACE' try_with(IDEO_SPACE, "C"); try_with(IDEO_SPACE, "en_US.UTF-8"); }

Possible output:

isblank(' ', locale("C")) returned false isblank(' ', locale("en_US.UTF-8")) returned true
