Inserting § in the chat bar kicks the player

when you execute:

/tellraw @a ["",{"text":"Click","clickEvent":{"action":"suggest_command","value":"§a Color!"}}]
MCEdit is needed for this

in a command block, you will be able to get the color symbol ( § ) in the chat bar. But once you press enter to send the colored message the game freezes.
