Serendipitously, your little OT exchange had a tangible benefit:

It led me to find out that, starting with ECMAScript 2016, there is, 
*finally*, a more convenient, Python-like way to write multi-line string 
literals than to suffix each line with “\n\”: template literals.

<http://www.ecma-international.org/ecma-262/7.0/#sec-template-literal-lexical-components>

Note that the characters produced by the /LineTerminatorSequence/ production 
are allowed to occur *unescaped* in such a literal.

Therefore, the ECMAScript 2016 program (which can be executed conveniently 
in, e.g., the Chrome DevTools console already)

  var argScott = `01010011
01000111

  console.log(window.atob(argScott.split("\n").map(
    (i) => String.fromCharCode(parseInt(i, 2))
  ).join("")));

  console.log(window.atob(argAndrew.split("\n").map(
    (i) => String.fromCharCode(parseInt(i, 2))
  ).join("")));

is syntactically valid and functionally equivalent to the Python program
I would have written instead:

#!/usr/bin/env python3

from base64 import b64decode

argScott = """01010011
01000111
…"""

argAndrew = """01010011
01000111
…"""

print(b64decode("".join(
  [chr(int(i, 2)) for i in argScott.split("\n")]
)))

print(b64decode("".join(
  [chr(int(i, 2)) for i in argAndrew.split("\n")]
)))

#---------------------------------------------------------------------------

However, that aside, Andrew, I do not follow your “argument”.  Is there a 
“$” character in Swahili?  Because that appears to be the only difference 
between your “argument” and Scott’s.

BTW: You are welcome, and Happy New Year.
