Copy pasting creates undesired behavior.

Pasting the following into my terminal:
echo -e "\e[1;31mSome red message\e[0m"

Will result in:
echo -e "\e[1;31mSome red message\e[0m""]]"

At first I thought it might be my terminal, but the behavior exists whether I use terminator, xterm, or the default terminal for Xubuntu 16.04.
