Datapacks that use section signs (§) in their folder name to add colour cannot be disabled using '/datapack disable X'

Steps to Reproduce:

1. Take any datapack and rename the folder, including a §

2. Apply this datapack to a world and join the world

3. Type the command ‘/datapack disable ’ and press tab until the renamed datapack is filled

4. Press enter

Observed Results:  

Player is kicked for “Illegal characters in chat” and the datapack remains enabled upon reloading the world

Expected Results:  

Datapack is disabled successfully, not kicking the player as the “Illegal character” wasn’t used in any chatting context
