There is a new bug that sends an Indian language (Telugu) character to your iphone, and Apple’s iOS Springboard will crash once the message has been received. So, if you see an Indian character, do not OPEN IT!
A new bug has been discovered in iOS 11 that lets people send a specific character that will crash an iPhone and block access to the Messages app in iOS and popular apps like WhatsApp, Facebook Messenger, Outlook for iOS, and Gmail. Italian Blog Mobile World spotted the bug, and we’ve tested it successfully on multiple iPhones running iOS 11.2.5, and found it also works on the macOS versions of Safari and Messages. Apple plans to fix the problem in an iOS update before the release of iOS 11.3 this spring.
Apple gadgets running iOS 11.2.5 or macOS, are susceptible to the bug, which disables access to iMessages.
Other popular messaging apps like WhatsApp, Facebook Messenger, Outlook for iOS, and Gmail, are also cut off.

The bug also affected macOS versions of Safari and Messages, but Apple’s public beta version of iOS 11.3 is unaffected, the Verge reported.
The only way to escape this cycle is to get someone else to message you and delete the thread containing the malicious message.
