Emojis cause incorrect displaying of the terminal

[dsseng]

Description

Emojis are displayed incorrectly.

Reproduction Steps

1. Try to paste 😀 into GNOME Terminal and Theia's terminal:
   GNOME:
   
   Theia:
   

OS and Theia version:
OS: Ubuntu 19.10
Default shell: zsh 5.7.1
Theia: master

Diagnostics:

I use zsh shell with oh-my-zsh, maybe it's related, but it's used in GNOME Terminal too.

I quickly verified on my side and it worked correctly:

Additional Info

I'm using bash_it and I'm on macOS.

So it is shell configuration issue, not something what can be addressed in Theia?

[dsseng]

Maybe it's browser-specific.

Maybe it's browser-specific.

It's shell specific. Before switching to zsh with Catalina, it worked. I think there is not much we can do.

[dsseng]

It looks like there isn't :(. Maybe it should be reported to Xterm.js, if they can't do anything report to Zsh.

[dsseng]

@kittaakos do you use oh-my-zsh too? if so, it can be their issue.

[dsseng]

In VS Code there isn't such issue.

[kittaakos]

do you use oh-my-zsh too

No, I don't.

@sh7dm you can give it a go to double check

[dsseng]

What can I check? Xterm.js? Zsh is fine in Gnome Terminal

[akosyakov]

Yes, I meant Xterm.js.
