In my discord guild i have some people with f****** ugly speudo with inexisting letters -_-"
( like : 𝒲𝑒𝓉𝓉𝒾𝓍 or Παπουνεττου ) ....

When this personne send message in discord, i can't see the speudo in minecraft ...

Quick fix => rename people in discord ... but bot use the username from user object ...
Or if you use the guild member object, you can have the nick attribute
