Terminal Support for Emoji

  Cross-platform, fast, feature-rich, GPU based terminal

I don't know of a single terminal that actually gets these ZWJ emoji sequences right. There are several terminals who will render them, but I haven't seen any actually get the width calculations correct. (E.g., https://github.com/kovidgoyal/kitty/issues/3810.) Part of the problem is that it really messes up the idea of a rectangular grid of base characters in memory, so you'll need some sort of indirection. Obviously I haven't tested all terminal emulators in existence, though :-)

I patched a similar bug in screen earlier this year (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1039503), which indicates the kind of stuff you have to go through.

  wcwidth for golang

Is it windows or is it golang making the difference there? Golang's implementation of wcwidth is different, and a commonly used lib has an 'emoji' table which covers that bomb (1F4A3)

The family emoji looks to have the wrong width, but it does resemble the behaviour supposed to be fixed by https://github.com/mattn/go-runewidth/pull/63 (see https://github.com/mattn/go-runewidth/issues/59 - like the flag example, that's multiple emojis with zwnj right?)

  A terminal for the web

  

I'm on the VS Code team and maintain xterm.js which is what Hyper's frontend is based on. There are actually multiple developments happening in this area.

First, there's a contribution from the author of DomTerm which adds grapheme cluster support to xterm.js, which will correctly merge and size things like emoji that are called out in the post. This is currently based on Unicode 15. See https://github.com/xtermjs/xterm.js/pull/4519

Second, while Windows Terminal does seem to work with emoji sometimes, it doesn't all the time. I'm not 100% sure, but I think it may only work on Windows ptys, not in WSL for example. Last time I spoke with the team they said they're working on a rewrite which could lead to proper emoji support.
