Oh god, that website though. How many CSS animations do I have to suffer through before it lets me scroll down to any actual information? Make it stop!!
Man, you weren't kidding! That is literally the most useless website I've ever seen. I spent over two minutes on it and still couldn't find a simple table of examples.
The examples on the IBM site had zeros without slashes or dots. And the character set showed a slashed zero exists, but it isn't the default zero. I believe you if you're using it, but I'm not sure where your dotted zero came from.
