Description

Description

Emojis are displayed incorrectly.

Reproduction Steps

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

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.

Contributor guide

Research direction
Investigate how Theia's terminal renders emojis and compare with GNOME Terminal's behavior. Focus on the terminal frontend code that handles character width and Unicode rendering.
