Have you ever received a message and wondered why you are seeing a couple of awkward boxes or out-of-context question mark symbols? You probably have, and possibly more often that you can even recall. However, life is too busy for us to worry about such trivialities, and we would simply just ignore them. But what if I tell you that maybe we need to worry about them a little more!
Before I get to explaining why we sometimes receive messages with inexplicable characters, you would likely want to know why should you care anyway. Fair enough!
