While looking at this, I noticed that Mozilla 1.3 on Windows XP displays the control characters using the old graphics characters that IBM stuffed into the control character slots of ASCII. I am not able to reproduce this either with MSIE or with Mozilla 1.2.1 on Win2K, so I suspect a lot of people are missing out on it. This is literally what it looked like to me on my WinXP machine last night:

write(1,"values of ♫B☼ will give rise to dom!\n",37);

I got the Unicode values for these characters from here. All these happy little music notes and shining suns really give an ironic edge to that whole "will give rise to doom" thing.
