I just recently discovered that in Safari (for Mac OS X Leopard), you can oscillate between text encodings, and considering the problem I and other users have had regarding Newgrounds' limited interface for Unicode characters (which I suspect Wade may have requested >:C), it may be worth my while to do this.
Now, here we go:

A heart, a spade, a club, a diamond and an umbrella
%u2665%u2660%u2663%u2666%u2602

A simple Japanese sentence
%u79C1%u306F%u732B%u304C%u597D%u304D%u 3067%u3059%u3002

Now I'll post this and toggle Unicode and see what happens...

EDIT: DAMMIT! It didn't work!
And this all started because of a handful of trolls...
AGH!
