On 0.53.0 and later, including 0.54.2, if I input an emoji into a TextInput via auto-complete, the app crashes.

I've tracked down the root cause; I'll put more details in a follow-up comment.

Environment

Environment:
  OS: macOS High Sierra 10.13.3
  Node: 9.7.1
  Yarn: 1.5.1
  npm: 5.6.0
  Watchman: 4.9.0
  Xcode: Xcode 9.2 Build version 9C40b
  Android Studio: Not Found

Packages: (wanted => installed)
  react: 16.2.0 => 16.2.0
  react-native: 0.53.3 => 0.53.3

Expected Behavior

No crash!

Actual Behavior
