[Message part 3 (text/plain, inline)]

This bug shows up with the code following:

;; 😄

(set-fontset-font "fontset-default" 'unicode "Apple Color Emoji" nil
'prepend)

(set-language-environment "UTF-8")

Steps to reproduce:
1. eval-buffer and the emoji doesn't show up correctly.
2. Comment out (set-language-environment "UTF-8") and run eval-buffer
the emoji shows up correctly.


I encountered this bug from Emacs mac port
bitbucket.org/mituharu/emacs-mac/src/work/ 28.0.92 to make sure it's
not only on that port, I download Emacs from emacsformacosx.com and
reproduced the bug. I found that emacs -Q is not available in Terminal so I
tested
it with no init files.

This is the first time I reported a bug to Emacs, please forgive me for any
inappropriate thing.

Great, thanks.  Then I think there's no Emacs bug here, and I'm
therefore closing this bug report.
