Fair warning: the first time you generate the page it can take several seconds and tends to bog down and occasionally crash the page. I usually get a "Page Unresponsive" warning, but clicking "Wait" does let it finish.
There will likely be a fair number of characters that don't show up. That' all based on the fonts available on your machine.
Clicking on a character copies the hex value for it to your copy/pasteboard and adds it to the list in the textarea below
When you're ready, click the button and the page will load the full set.
What renderers is dependent on the fonts on your machine
I've got large swatches where nothing renders. Not sure if that's font related or if stuff haven't been defined there yet
These are all characters from 0x21 to 0x1eeff
Characters 0x00 to 0x20 are invisible spaces and control characters. I didn't include them
I stopped at 0x1eeff since that's the last one referenced in the W3C Redommendation
