An innocent-looking message, containing characters in the Sindhi language, can cause your iPhone, iPad, Mac, or even Apple Watch to crash without warning. Problem appears to exists in how the latest shipping versions of Apples operating system handle a Unicode symbol representing specific characters written in Sindhi, an official language in part of Pakistan. The problem occurs most irritatingly when your device attempts to display a message notification which includes a preview of the message. Android users, meanwhile, are unaffected and can watch the chaos with bemusement.”]
