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.

And apparently Twitter puts the content of a tweet in the tag if you are on the page for a single tweet. Surprised that doesn't cause more problems.

Nope, Twitter uses a shortened, ellipsized version of the tweet as ... . Still, if there's Unicode in the shortened version, it might have the same outcome.

This is the tweet in html character entity form: ه҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈ͫͬͩͮͨͪͯͥͥͫͪͧͣͯͪͨͣͥͬͪ҈҈҈҈҈҈҈҈҈҈&#1160…

Would you mind indenting that two spaces so it shows up

  like this

rather than breaking the page layout?

Does anyone else see something funky at the top most comments?

I do. Some justaposition of random chars. I'm on an iPad, what's your machine?

I see it on my Macbook in Chrome running on Mountain Lion.

This is crashing nightly webkit as well, so it is likely an issue there.

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.

Windows 7 - Google Chrome 24.0.1312.57m

It's a little laggy, but it's rendering okay. Might be an OSX-localised issue.

Maybe depends upon language settings?
