A simple pythonscript to encode ascii text to whitespace and back

ws.py

#!/usr/bin/env python3

import sys

spaces = " \u180e\u2000\u2001\u2002\u2003\u2004\u2005\u2006\u2007\u2008\u2009\u200a\u202f\u205f\u3000"

def encode(s):
    res = ""
    for c in s:
        c = ord(c)
        res += spaces[(c & 0xf0) >> 4]
        res += spaces[c & 0x0f]
    return res

def decode(ws):
    res = ""
    for (a,b) in zip(ws[::2], ws[1::2]):
        res += chr(spaces.index(a)*16+spaces.index(b))
    return res

if len(sys.argv) == 1:
    print("Usage: {} [string_to_encode|string_to_decode]")
elif all(c in spaces for c in sys.argv[1]):
    print('Decoded to "{}"'.format(decode(sys.argv[1])))
else:
    print("Encoded between [] -> [{}]".format(encode(sys.argv[1])))

The same script, whitespace encoded:
