Vscode: [Linux] Emojis not displayed correctly

[teohhanhui]

Issue Type: Bug

Some emojis are displayed as the text variant (not coloured). Other emojis are displayed as square boxes. This happens in both the editor and built-in terminal.

I've tried with the following settings:

{
    "editor.fontFamily": "'Fira Code', 'Noto Sans Mono', 'Noto Sans CJK TC', 'Noto Color Emoji', 'monospace', monospace, 'Droid Sans Fallback'",
    "terminal.integrated.fontFamily": "'Hack', 'Noto Sans Mono', 'Noto Sans CJK TC', 'Noto Color Emoji', 'monospace', monospace, 'Droid Sans Fallback'",
}

The emojis are displayed correctly in other apps, including in Firefox, Google Chrome, and Gnome Terminal.

Looks like doing chsh -s /usr/bin/bash has fixed the problem. Manjaro Gnome recently switched to zsh as the default shell.

Closing because it seems to do more with the shell than VS Code.

[teohhanhui]

I don't see how it makes sense that using a different shell would break this for vscode. I think this warrants more investigation.

Hmm, if bash fixes it and zsh doesn't then chances are they're sending different data for the various emoji. Some more info that would be useful:

• Which emoji you're using
• Show a screenshot of bash vs zsh

I don't have a Manjaro setup, but the next steps would be figuring out what the shell is sending over and checking if this is reproducible also in xterm.js and fixing it there as that's the terminal frontend project.
