That's not a format, it's a user interface ("the user is presented...")  
Unicode doesn't standardize user interfaces. Restricting the permissible 
alphabet to emoji is just about as bad/annoying (for many users) as 
restricting it to ASCII or Cyrillic or whatever, except that it's more 
evenly hard on everyone.
