[MC-255284] Players with name containing chars higher than 127 can't join on servers

In the sourcecode of minecraft this function is used to verify username validation

Source code example

public static boolean isValidUsername(String s) {
      return s.chars().filter(paramInt -> (paramInt <= 32 || paramInt >= 127)).findAny().isEmpty();

The problem is that there are existing users that will fail this check.
