Hello! SmPL doesn't support the character constants of the form: u'c', U'c', L'c' nor the string literals of the form: u8"", u"", U"", L"" A test case is attached as a patch for the coccinelle tests. minus: parse error: File "tests/wchar.cocci", line 8, column 22, charpos = 106 around = ''', whole content = - char16_t zero = u'\0'; thanks bye michael
