I got unreadable code while running install_docker.sh

after running the installation command, I got log like following:

$ bash docker/scripts/install_docker.sh

where my locale is as following:

what's wrong with me?

I guess it only impacts the help msg. Is docker installed in your env? Try docker ps

Here is the output from my dev box.

It looks like that there's something wrong with my local env or my terminal. Linux cmd messages always gets to be messy.
NOTHING is wrong with Apollo. Thanks!
