Originally created by @hsiktas on GitHub (Aug 6, 2019).

Environment

Windows build number: Microsoft Windows [Version 10.0.18362.267]
Windows Terminal version (if applicable): 0.3.2142.0

Any other software?
Ubuntu 18.04 running in WSL1 with zsh as the default shell.

Steps to reproduce

apt install sl lolcat in case they are not installed yet.
Then run sl | lolcat

Expected behavior

A colorful steam locomotive runs over the screen and my productivity increases by 0.2 %.

Actual behavior

🤷‍♂️
sl works on its own but when piped through lolcat, I only see hundreds of lines of colorful gibberish scrolling by.
