The current version of iOS 11.2.5 showed an interesting bug. One of the symbols of the Telugu language used in some states of India leads to a reset of the iPhone. Foreign resources paid attention to this .
If you insert a symbol into the text or open a message with it, the smartphone will go into reboot. Found that the bug is triggered with Facebook Messenger, iMessage, WhatsApp, Gmail, Outlook, but not Telegram and Skype. Apparently, the problem affects only one character and does not apply to others.
The same symbol:

It is noted that in the smartphone with the beta version of iOS 11.3 this bug is not. Presumably, Apple knew about the problem and already fixed it in the future version of the operating system.
