Speaking of Unicode, I think my favorite Unicode range is U2600-U26FF, "Miscellaneous Symbols". Talk about miscellaneous! Not only does it include characters like card suits and smiley faces that are in most traditional fonts, but also:

chessmen (the whole set, in both white and black)
religious symbols
signs of the zodiac
radiation and biohazard warning symbols
skull and crossbones
hammer and sickle (I knew Unicode was a commie plot!)
way too many variations of the recycling symbol (the environmentalist wackos are in on it too!)
