Minecraft crashes when trying to render supplementary character (UTF-16) in right to left language

The bug

All my players use Minecraft in Hebrew interface.
If we copy emoji (for example form this site: http://getemoji.com/) and paste it in the Minecraft chat the game will crash for several players in the server.
If you named something (a minecraft:book for example) with the emoji you copied, anyone that look at that something it will crash his game.

How to reproduce

  1. Set the language to one which is read and written right to left, for example Hebrew
  2. Paste any supplementary character (UTF-16) like 𐀀 (U+10000) in any text field for example the chat
