Bash get unicode character from encoded char
Use hexdump to lookup the 6-digit unicode sequence. Examples for bash and python are given.
$ echo -n ✓ | hexdump
0000000 e2 9c 93
0000003To print the character, escape the 6-digit / 3 byte unicode sequence. Use -e with echo to interpret the escaped characters.
$ echo -e "\xE2\x9c\x93"
✓Example with color and subscripts on the command line:
$ echo -e 'O\xe2\x82\x82 Sensor: \x1b[1;32m\xE2\x9c\x93\x1b[0m'
O₂ Sensor: ✓To print the unicode character in python, do the following:
>>> print "\xE2\x9c\x93"

These color codes are incomplete for some reason beyond my knowledge and fail sometimes when a line is too long, overwriting the prompt's first line content and producing weird behaviours because prompt won't start a new line or even go one line up.
In order for these color codes to work (at least in ubuntu), you need to replace
\e with [\033 and add at the end of every code \].
So instead of
Red='\e[0;31m' # Red
You should type
Red='\[\033[0;31m\]' # Red
It's also possible to get the unicode sequence on the command line using python:
$ echo -n "✓" | python -c 'import sys; print [sys.stdin.read()]'
['\xe2\x9c\x93']
$ echo -n "â€" | python -c 'import sys; print [sys.stdin.read()]'
['\xe2\x80\x9d']
