Please tell:
. does this happen in "emacs -Q", if you evaluate the above
immediately upon entering Emacs?
. what is the language environment before the evaluation of
set-language-environment above?
. what is the output of "M-x describe-fontset RET fontset-default RET"
after evaluating set-language-environment, in particular in the
Emoji block starting from #x1F600?
. what did you mean by "emoji doesn't show up correctly"? how was it
displayed "incorrectly"?
And I have 2 comments, which may or may not be relevant to this issue:
1) It is a very bad idea to do the likes of
(set-fontset-font "fontset-default" 'unicode "Apple Color Emoji" nil
'prepend)
That's because the character set 'unicode spans the entire range
of Unicode characters, and there's no single font that can
possibly support all of those characters.
2) You should set the language environment _before_ any other
customizations related to character sets and fonts, because the
language environment affects those customizations.
Thanks.
