System font used for emojis

[turt2live]

Steps to reproduce

1. Open the app
2. Send a flag emoji

Outcome

What did you expect?

Our specific font emoji.

What happened instead?

This should be a Canadian flag, but Windows doesn't have proper flag emoji so it renders like this.

This broke with today's nightly.

Operating system

Windows 11

Application version

Element Nightly version: 0.0.1-nightly.2023112401 Crypto version: Olm 3.2.15

How did you install the app?

The Internet

Homeserver

t2l.io

Will you send logs?

Yes

This was done intentionally, twemoji no longer receives updates due to twitter>x. You can enable the bundled (outdated) font under settings > Appearance or update your system fonts

I honestly cannot believe that Windows 11 doesn't have a 🇨🇦 emoji. Have you customized any font settings at the OS level?

[turt2live]

Nope, this is a stock Windows install. Windows has never had country flags in its emoji font, which makes issues like this easy to check :)

[Johennes]

Ok, we might have to reconsider twemoji alternatives then.

[Johennes]

Tested myself and while most emoji from our picker are present on Windows a few notable ones and most country flags are missing.

So the gaps aren't giant but still quite annoying and it worries me when not even Windows has good emoji coverage. @t3chguy is going to revert the change mentioned in #26643 (comment) and we'll reconsider alternatives.

A quick Google search turned up https://github.com/googlefonts/noto-emoji. It has a concerning disclaimer in its README...

NotoColorEmoji uses the CBDT/CBLC color font format, which is supported by Android and Chrome/Chromium OS. Windows supports it starting with Windows 10 Anniversary Update in Chrome and Edge. On macOS, only Chrome supports it, while on Linux it will support it with some fontconfig tweaking, see googlefonts/noto-emoji#36. Currently we do not build other color font formats.

...but appears to be working fine in my quick testing with Firefox on macOS.

I'm using Arch and the noto-fonts-emoji package comes with just the font itself and the license file. I didn't do any special configuration to make it work.

[Johennes]

What I meant above was that we could bundle Noto instead of Twemoji. So then I think you wouldn't have to have it installed on your system.

Of course but your quote mentions some tweaks needed for Linux. That's not my experience, which is a positive thing.

Ohh, I see. Sorry, had misunderstood you.

An upside to the Windows default font is I could finally see the + emoji, for once:

Not sure matrix-org/matrix-react-sdk#11935 worked:

The option is checked:

but isn't being applied:

[t3chguy]

@turt2live have you tried turning it off and on again? Sounds like #26248

[turt2live]

Turning it off and on works for the active session, but after I reload it's back to being unbundled emoji. There is a notable light->dark switch during my application load, however.
