Copy and paste from Discord:
Hello, a couple of my players are experiencing an issue where the kit I made that gives them their head is giving them a steve head, and in the name, it's including characters that aren't in the players username. Any idea on how to fix this?

 myhead:
delay: 86400
items:
- playerhead 1 player:{USERNAME}

2.22.0-dev+21-e9da116 | Paper version 1.21.8-51-main@b6168b7

I had this specific player try on a vanilla client as well
I realize, it's only happening to players with _ in their name, it's auto adding \ before it.
I quoted - playerhead 1 player:{USERNAME} with " and ', but still occurs.

`- playerhead 1 player:Siedler32_ ` will give me the players head in this screenshot correctly, but this does not help me as I need one kit for everyone

Steps to reproduce

Create a Kit to give a head of the kit command executor

Expected behaviour

For the head to be given with the skin of the player in the placeholder - and not forcing \ inside the name of the head.

Actual behaviour

Explained above...?

Additional Information

Was told to do a report on this from Jason in Discord.

Hello, a couple of my players are experiencing an issue where the kit I made that gives them their head is giving them a steve head, and in the name, it's including characters that aren't in the players username. Any idea on how to fix this?
                       myhead:
delay: 86400
items:
- playerhead 1 player:{USERNAME}

                      2.22.0-dev+21-e9da116 | Paper version 1.21.8-51-main@b6168b7
                      I had this specific player try on a vanilla client as well
                      
I realize, it's only happening to players with _ in their name, it's auto adding \ before it.
                      
I quoted - playerhead 1 player:{USERNAME} with " and ', but still occurs.
                      `- playerhead 1 player:Siedler32_ ` will give me the players head in this screenshot correctly, but this does not help me as I need one kit for everyone 
                      Steps to reproduce
                      Create a Kit to give a head of the kit command executor
                      Expected behaviour
                      For the head to be given with the skin of the player in the placeholder - and not forcing \ inside the name of the head.
                      Actual behaviour
                      Explained above...?
                      Additional Information
                      Was told to do a report on this from Jason in Discord.
