Why do you think what they do is "correct"?  AFAIK, we use the Unicode
Standard's definition of Emoji sequences to decide when U+FE0F
warrants an Emoji representation.  maybe those other applications
default to Emoji representation of every character that can possibly
have such a representation, but in Emacs such a default cannot make
sense.
