According to The Verge, the only way for users to recover their message app is to have someone send another message, try to access messages and delete the thread of messages with the special character.
Other popular messaging apps like WhatsApp, Facebook Messenger, Outlook for iOS, and Gmail, are also cut off.
A new iOS bug that can crash not only Messages but third-party messaging apps has been discovered, potentially leaving the app unusable by receiving a single character.
The iPad immediately crashed when the messages were received; iOS's notification bar failed to process them, forcing the whole system to stop and reload.
'If the character is displayed within an application, the app in question will crash and will continue to close each time you try to start it.
The problem also affects the software which powers Mac computers, Apple Watches and Apple TV devices.
It's already bad enough that Variety is also covering this latest mishap from the Apple iOS team.
Apple promised to address the issue with an update before it rolls out a new version of its iOS this spring.
The character being talked about here belongs to the Indian language Telugu. If the person sent you the character not as a joke but in an attempt to cause your iPhone harm, chances are, you're not going to be able to coax them into letting you regain access to your Messages. All someone with malicious intent has to do is send you a specific Telugu character to your iOS device to ruin your day.
The fix will arrive "ahead of their next scheduled major updates" which is iOS 11.3 (stable).
