Logged In: YES user_id=21627 You are right, the code should use iswprint instead. The point is that multiple subsequent bytes can make up a single printable character. Not every character above 127 is necessarily printable (e.g. in Latin-1, only characters above 160 are printable). Likewise, a single byte may not be printable, but a combination will print fine. So this code is supposed to catch only those cases where printing will actually work.
