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

[beaumartinez]

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

I use font Menlo.

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

vim --version

Only happens in CoreText renderer. Will look into it.

Not sure if it's related, but the ⚠️ emoji appears as what I think is a Č, using the Hack font. It looks fine in my terminal (which also uses the Hack font).

@theunraveler this is font-specific. with Fira Code Light it doesn't happen. Not all fonts process it well and I have a test in my .vimrc to test everything.

[theunraveler]

If it were font-specific, wouldn't it also look different in my terminal (which uses the Hack font)?

[eirnym]

I know, that Terminal.app overrides the emoji range to substitute with another font. And as far as I remember, MacVim only uses this technique only if font doesn't define support for specific code-points.

I just installed to test the newest Hack font with the latest MacVim release on 10.15 and it renders correctly various emoji. They're 2-char wide, so they're clipped as was discussed in this issue (even Terminal.app clips them)

Also there was a closed issue to the Hack font to support Emoji
