Can your terminal do emojis? How big?

I'd be happy if we could get terminals to agree on how wide the warning triangle emoji renders. The emoji are certainly useful for scripts, but often widths are such a crapshoot. I cannot add width detection to every bash script I write for every emoji I want to use.

If only there was a standards body that could perhaps spec how these work in terminals.

You could ship a terminal with your script. This is how apps like Slack deal with inconsistent handling of standardized content by shipping an embedded chromium.
