When the null Unicode character appears in chat, the game output shows the error
<log4j:Event logger="net.minecraft.server.MinecraftServer" timestamp="1654584991672" level="INFO" thread="Server thread"> <log4j:Message><![CDATA[<> hi]]></log4j:Message> </log4j:Event> XML_ERROR_PARSING_CDATA <log4j:Event logger="egt" timestamp="1654584991679" level="INFO" thread="Render thread"> <log4j:Message><![CDATA[[CHAT] [] hi]]></log4j:Message> </log4j:Event> XML_ERROR_PARSING_CDATA
An example of how you can reproduce this:
- Summon an entity, such as an Armor Stand, with it's name being the Unicode value for null. (Running the following command in chat also gives the error, but in a command block it does not. I was testing using a command block.)
/summon minecraft:armor_stand ~ ~ ~2 {CustomName:'{"text":"\\u0000"}', CustomNameVisible:1b}
2. Run a command that will cause the null character to show up in chat, such as
/execute as @e[type=minecraft:armor_stand, limit=1] run say hi
The game output now shows the error shown above.
