Everytime I run docker-compose up on my machine (macOS 10.13.5, latest docker version) I get this error

My first instinct is that this error means what it says: you somehow have the byte 0x80 in some file in your system (maybe not the docker-compose.yml) and it’s not UTF-8-encoded text. – David Maze

Ok so apparently there is a problem with the current version of docker-compose for macOS... It's just my guess, but anyhow here is how I solved it

curl -L https://github.com/docker/compose/releases/download/1.14.0-rc2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

Then restarted the terminal

I have 2 ideas: 1. try to reinstall your python 2. use not the latest docker version, but the latest stable

What worked for me was creating an empty .env file in the directory I run docker-compose in (encoded as UTF-8).

I ran into this same issue and this may also be related to your .env files.

Ensure that your .env files are UTF-8.

sudo apt install moreutils
isutf8 yourfile.env

If isutf8 returns no output it's likely a valid UTF-8 file.

Additionally, check the contents of the .env file you're referencing in your docker-compose.yml. Any incorrectly decrypted secrets/values you may be using locally can cause this problem too.

If in doubt, clear the env file and readd lines until you hit the error.
