(1) When for ex. you like to change the text on a birch_sing to ,,I like Minecraft,, in the second line with a command, you´ll get a error in the chat (Photo). The sign has the same text after this.

(2) The same happen when you´ll do a setblock-command or a give-command, but the sign will create. 

 

Command: (1) /data merge block ~ ~ ~ {Text1:"",Text2:"

{\"text\":\"I like Minecraft\"}

"} 

Command: (2) /give @p minecraft:birch_sign{BlockEntityTag:{Text1:"",Text2:"

{\"text\":\"I like Minecraft\"}

"},display:{Name:"

{\"text\":\"sign\"}

"}}

Command: (2) /setblock ~ ~ ~ minecraft:birch_sign{BlockEntityTag:{Text1:"",Text2:"

{\"text\":\"I like Minecraft\"}

"}}
