emacs -Q
M-x load-library isearch.el
C-h f isearch-forward
In buffer *Help*: C-x C-w foo.txt

You get a coding-system warning.  I tried saving it as utf-8 and as raw
text.

In both cases, when I open that file in a new Emacs session, I see octal
escapes where there were curly quotes.

Why were there curly quotes?  Because `C-h f' produces curly quotes.

This is a regression - no such problem exists with Emacs 24.5 (or prior).

In order to produce a reasonable, readable file from the *Help* buffer
that I attached to the following mail message to emacs-devel <at> gnu.org,
I had to resort to using Emacs 24.5:

 "RE: Exposing Isearch toggleable options", 2015-10-28, ~21:20


(BTW, it is apparently *not* the case, in spite of what is stated at
http://lists.gnu.org/archive/html/emacs-devel/2015-10/index.html, that
the mailing list archive is updated every 30 minutes.  Far from it,
it seems.  That's why I didn't provide a URL to the emacs-devel post.
Got tired after 1/2 hour of waiting for it to show up.)

Thanks, I fixed the first part of this: Emacs should no longer ask
annoying questions when you save help buffers with curved quotes.

The second part, which happens when visiting the saved file, is not a
bug: you need to specify the encoding of files when visiting them in
locales whose default encoding is different.  (Actually, I expect this
to work automatically for you, at least in "emacs -Q", but that
doesn't happen in every locale.)
