Fancy output crashes terminal

[bdomars]

What happened:
Tried running kind create cluster and terminal just closes after a couple of lines of output.

What you expected to happen:
Get the normal output and terminal stays open.

How to reproduce it (as minimally and precisely as possible):
Run kind create cluster in the st terminal emulator.

Anything else we need to know?:
Verified that this works fine using gnome-terminal also works in st if I run it with the -q flag so it seems to me that it's the fancy output that st does not like.

Environment:

• kind version: kind v0.9.0 go1.15.2 linux/amd64

• Kubernetes version:

KIND respects https://en.wikipedia.org/wiki/Computer_terminal#Dumb_terminals (TERM=dumb) and https://no-color.org/

This sounds like a bug in your terminal emulator.

[BenTheElder]

What TERM does st set? is there any way to identify running inside of st?

These "fancy" characters are unicode (utf8) + a few VT escape sequences, which should work fine in 2020, but we already automatically disable them in a few known-broken environments (e.g. travis-ci's tty emulation), if it's possible to detect st specifically we can add that.

Yeah, this might also be a bug with st. They at least have some known issue with Xft causing it to crash with "colored emojis" whatever that means.

TERM is set to st-256color
