Letter 🅱️ prints as ¥ in MacVim (but not in terminal Vim or less)

Try typing 🅱️ (or opening a text file with that in it) in MacVim. It will display it as ¥.

If you inspect the character with :ascii you see it is the correct character in the status line, albeit it displayed as the text version of the emoji. Writing the file correctly writes it as 🅱️, it just displays as ¥.

Opening it with Vim on Terminal.app displays it correctly, as does with less.

Here's my MacVim version

VIM - Vi IMproved 8.1 (2018 May 18, compiled Aug  8 2018 18:09:39)
macOS version

I use font Menlo.

Here's my Vim version (it's the same one)

vim --version
VIM - Vi IMproved 8.1 (2018 May 18, compiled Aug  8 2018 18:09:39)
macOS version

I'm running on macOS High Sierra version 10.13.6 (17G65).

Commencez par reproduire le problème d’affichage dans MacVim sur macOS High Sierra avec la police Menlo, puis comparez le même emoji dans Terminal Vim et less. Utilisez :ascii et un fichier enregistré pour vérifier que le caractère reste correct ; c’est terminé lorsque 🅱️ s’affiche comme l’emoji plutôt que comme ¥, sans modifier le caractère écrit.
