iOS update: New Apple software stops iPhones breaking if they see just one letter

Apple has finally fixed a bug that meant iPhones could crash if they saw just one character. Last week it emerged that when iPhones were sent a character in Telugu, a popular Indian language, the phone could stop working entirely and crash. It would have to restart itself before it started working again. Now the company has rolled out an update – iOS 11.2.6 – that will fix that issue. It doesn't bring any major new features apart from that change, but big alterations are coming soon.
