Text message crashes iphone

This particular text locks iphone users out of their messaging app if sent via text message. I think its some sort of malformed unicode, but in any case this is not ok apple.

Seems to be an overflow buffer attack that predominantly effects 5s users.

I don't think it's a buffer overflow attack. Seems to be something wrong with rendering Arabic text when a message is shortened.
