That doesn't render 100% for me, lots of square boxes.

What are you using? On Firefox on Linux I get this: http://i.imgur.com/Xspttp3.png

That's really fascinating that it results in different output depending on your browser.

Strange, mine was from Safari on OS X.

Switch the page encoding to Thai.

Once had this dude sign up for our page management... we had a lot of assumptions about plain or at least sane text that had to get updated. https://www.facebook.com/glitchr

That is hilarious. Can't scroll down without it crashing the tab.

Works fine on Chrome 25.0.1364.97 on Ubuntu 12.10. Is this a browser issue or something with the underlying platform font rendering libs ?

The problem seems to be restricted to Windows - apparently it looks normal on Ubuntu and Mac. (Here: Mac 10.6, works fine on Chrome, Firefox and Safari.) So I guess it's a platform issue.

Crashes both Safari 6.0.1 and Chrome 25.0.1364.155 on OSX 10.8.2 over here.

Chrome on Win7 64-bit here; it does not crash as I scroll down.

Same here. Crashes in Chrome. I wonder if that could be exploited...

There's a twitter account, glitchr which posts lots of these things: https://twitter.com/glitchr_

glitchr's tweets may cause other twitter clients to crash too, eg this one (you have been warned!) https://twitter.com/joshlogan42/status/303975029698342912

In cases like this it is useful to post a short description of the link. Like this: http://stackoverflow.com/a/1732454 (the famous "don't parse HTML with regex" cry for sanity, semi-relevant because of zalgo text.) FTFY
