In August 2013, users of iOS 6 and OS X 10.8 suffered from a bug that caused applications to close when a certain string of Arabic characters was shown due to a bug in WebKit.
For something similar has now been discovered.
Screenshot: MacRumors.The character system Unicode iOS that sits inside the CoreText API also crashes when you receive the above message (either via SMS or iMessage), discovered by users of the Reddit. It affects the current version (8.3) and possibly several previous ones as well.
It is curious that the bug seems to affect only the Notification Center, either on the locked screen or in the system of notification of messages by banner at the top of the screen (when you are already using the device). When it occurs with the screen locked, you need to receive new “normal” messages until the problem is out of sight to be able to use the device again.
As iOS 8.4 is already in advanced testing phase, it is possible that Apple will take the opportunity to fix the bug in the package of this update.

An Apple representative told the iMore that the company is already aware of the bug and that it will fix it in a future iOS software update.
Update II, by Eduardo Marques · 06/10/2015 s 16:25
As reported by the HDblog.it (Google Translate), the iOS 8.4 beta 4 (released by Apple this week) already brings a fix to the problem. The final corrected version of the operating system will be made available to the general public on 6/30.
It is worth noting that the bug not only affects the Messages app on iOS, but also on Mac and Apple Watch, in addition to also crashing third-party apps like Snapchat, Twitter and WhatsApp since the problem is linked to the way the notification banners process Unicode .
