From the article above:
> If you look at the first 32 characters in the IBM PC character set you’ll see lots of whimsical characters — smiley face, musical notes, playing card suits and others. These were intended for character based games — see “Snipes” if you can still find a copy.

> Now, what to do about the first 32 characters (x00-x1F)? ASCII defines them as control codes, carriage return, line feed, tab… These characters originated with teletype transmission. But we could display them on the character based screens. So we added a set of “not serious” characters. They were intended as display only characters, not for transmission or storage. Their most probable use would be in character based games.
