The offending tweet content:

      ه҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈ͫͬͩͮͨͪͯͥͥͫͪͧͣͯͪͨͣͥͬͪ ҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈ͪͥͨͪͫͬͭͮͯͥͤͣͥͨͪͧͣͯͬͪ ҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈҈ͪͨͪͫͬͩͮͯͥͨͣͥͫͪͧͣͯͥͬͪ

Edit: I've narrowed it down to the following byte sequence. I can't seem to remove any of the characters without it no longer crashing:

    00000000  d9 88 d2 88 cd a5 cd a8  cd aa cd af 20 d2 88 d2  |............ ...|
    00000010  88 d2 88                                          |...|
    00000013

Hixie's unicode decoder says this is:

    U+0648 ARABIC LETTER WAW character (&#x0648;)
    U+0488 COMBINING CYRILLIC HUNDRED THOUSANDS SIGN character (&#x0488;)
    U+0365 COMBINING LATIN SMALL LETTER I character (&#x0365;)
    U+0368 COMBINING LATIN SMALL LETTER C character (&#x0368;)
    U+036A COMBINING LATIN SMALL LETTER H character (&#x036A;)
    U+036F COMBINING LATIN SMALL LETTER X character (&#x036F;)
    U+0020 SPACE character
    U+0488 COMBINING CYRILLIC HUNDRED THOUSANDS SIGN character (&#x0488;)
    U+0488 COMBINING CYRILLIC HUNDRED THOUSANDS SIGN character (&#x0488;)
    U+0488 COMBINING CYRILLIC HUNDRED THOUSANDS SIGN character (&#x0488;)

Is this a mountain lion issue or does this affect lion and SL as well?

Not seeing any crashes on 10.6.x ("Snow Lion") here.

It also crashes Chrome's current tab on OSX: http://imgur.com/vRn6Qid

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

Not for me either with the same version. It doesn't even render, but it doesn't crash.

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

firefox 18.0.2 on osx seems to survive...

Though it does do unholy things to the tab/window title... :)

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.

It's "Snow Leopard". Apple isn't running low enough on cats to have to resort to mythological ones just yet ;-)
