Manish Goregaonkar has published this absolutely fascinating analysis of the iOS crashing bug that occurs when it comes across a particular text string.
So there’s yet another iOS text crash, where just looking at a particular string crashes iOS. Basically, if you put this string in any system text box (and other places), it crashes that process. I’ve been testing it by copy-pasting characters into Spotlight so I don’t end up crashing my browser.
I was pretty interested in what made this sequence “special”, and started investigating.
Even if you are not interested in the technical details, I urge you to go read it. The explanation about Indic scripts is incredibly interesting read.
