Yes. But the "ACTUAL content" has to be UTF-8 encoded Unicode.

Yes.

It depends how you define the terms "straight text" and "binary
data" in this context. It is not ASCII data that's for sure.

Yes. It *must* be UTF-8 but it's not. Hell, let's look at it:

$ python -c "import
base64;unicode(base64.decodestring('NjE1LCBydWUgQm9vdGgsIDZl98l0YWdlLCBwaehjZSA2NTA='),'utf-8')"
Traceback (most recent call last):
  File "<string>", line 1, in ?
UnicodeError: UTF-8 decoding error: invalid data
$ python -c "import base64;print
repr(base64.decodestring('NjE1LCBydWUgQm9vdGgsIDZl98l0YWdlLCBwaehjZSA2NTA='))"
'615, rue Booth, 6e\xf7\xc9tage, pi\xe8ce 650'

No.
