Interesting on chrome Version 24.0.1312.57 the tab crashes when i try to view the tweet but not here. Can someone explain what is happening and why the tweet is affecting the tab and this post does not? In the end both just render unicode characters. And it looks like only Firefox is able to display it correctly on OSX 10.8.

Chrome uses OS X's CoreText for rendering the tab titles, but uses its own text rendering engine for the site body. CoreText is the one that crashes on that unicode.

How do you type this on a Mac?

You could turn on "Unicode Hex Input" in System Preferences > Language & Text > Input Sources and type in the unicode characters one at a time.

Earlier quoted context omitted.

Weird, not for me. No crash with Chrome 24.0.1312.57 on OSX 10.6.8.

I'm using 24.0.1312.57 on OSX 10.8.2. Perhaps it is a Lion/Mountain Lion thing.

I'm using Mountain Lion as well, and no crashes.

Crashes Chrome on Mac (only the tab, not the whole process). Of course retweeted it!

No crash on either Chrome or Firefox on Arch Linux.

Rendering any typeable character(s) should never crash any engine... ever. That said, unicode seems to be the last frontier for the non-viral spread of glitches.
