Pretty Serious Unicode of Death Bug - crashes iPhones, Safari on OSX, and current tab in Chrome on OSX
If you are on OSX, use Firefox to display it, as Firefox uses it's own font rendering engine.
For anyone that can actually read Arabic, you'll know that is basically gibberish.
However, this string of text...if sent to ANY (I mean ANY) of the millions of iPhones in the world, it will crash the Text Messaging app and will be at the mercy of the sender to have the Text Messaging app restored, or you will have to restore the iPhone.
If this text is shown on Safari on OSX, it will crash Safari.
If this text is shown in Chrome on OSX, it will crash the Chrome tab.
If this text is shown in Opera on OSX, it will crash the tab in Opera.
Facebook has already blocked the text.
Firefox, however uses it's own text rendering on OSX, and will display it fine (the only way I'm able to type up this post.).
Basically any browser that uses the iOS/OSX Web Rendering Engine.
If this is sent via iMessage or Messages it will crash the Messaging app in an endless loop. I have pissed someone off doing this without prior notice.
I have not tested it, but sending it via email will also crash in an endless loop for iOS, and the results are the same for Safari on iOS (browser will crash).
The bug occurs in the current version of OSX (10.8) Mountain Lion and iOS6.
The bug is fixed on iOS7 devices and in Mavericks (10.9) for OSX.
But for right now, this bug will affect basically 90% of the world with iPhones and Macs. To me, this is an extremely dangerous bug, and I recommend if any of you in IT have a way to block this, it will make your week a lot easier to deal with, as Apple pushes users to iOS 7. Apple has not as of now, issued a patch for this.
EDIT: Because the way SD displays text, this is not a good example (it will not crash, it will for me when I go to edit the post, but not when it is displayed on SD. If you are on OSX in Safari or on iOS or Chrome, you can test this bug by going here..
