How to fix myessaging app on iPhone?

I received one of those Unicode text that messed up the messaging app on my iPhone. Whenever I try to open the app, it immediately crashes. I have tried fixes that other people use, and none of them work. I have rebooted my iPhone. Sent message to myself through Siri, sent picture to myself. But I don't know who sent me the message. When I double click the home button to open multi tasking pages the messaging app only shows my messages before I got the Unicode message. How can i fix this? Or when will apple release an update to fix this?

Apple already said they are releasing a patch for that, for now if you just turn off banner notifications then it doesn't cause the reboot.
