A character from the Indian Telugu language will crash multiple applications on iOS and macOS, an Italian blogger has discovered.

The character in question is ” జ్ఞ‌ా “, which, if sent to another user, will prevent that user from opening apps such as Messages, WhatsApp, Facebook Messenger, Outlook for iOS, Gmail, and Twitter.

In an Open Radar bug report filed on Monday, Apple said it already patched the issue in the beta version of iOS 11.3. Fixes are expected when Apple releases updates for iOS and macOS later this month.

The bug is causing quite some problems for iOS and macOS users, as iOS and Mac apps will always try to resume from where the user left off the last time.

For example, if a user has received a WhatsApp message with this character, the WhatsApp application will crash in an infinite loop until the user receives a new, different message, or he uses the app’s web interface to remove the message/update containing the problematic character.

The bug doesn’t manifest all the time on macOS, only for some apps, but it’s a big issue for iOS users primarily.

Last month, iOS users had to deal with another similar bug called chaiOS that also crashed the Messages app on iOS.

Like chaiOS and most similar bugs, this recent issue will be heavily abused for pranks. If you find unable to use some apps, somebody sending you an obscure Indian character might be the reason why. Below is a video recorded by Italian blog Mobile World showing the bug in action:
