I have tons of stuff in my setup.  Let me know what I might search
for that might affect encoding/decoding.

Such as?  Again, could it be affected by the default font choice?

Please read again what I said about the crash.  I think it
at least explains why I saw octal escapes when I visited
the last-saved file - it was saved with raw text.  Only the
auto-save file was saved with utf-8.  When I visited the file
in a new session, it showed the octal escapes because it was
saved as raw text.

Why that happened I'm not sure.  Perhaps when I did `C-x C-w'
the *Help* buffer was first saved as raw text (?), then
autosaved as utf-8, then the crash interrupted finally
resaving the file itself as utf-8 (?).

You will need to give me an idea what to look for, if I am to
try hunting for something in my init file and all that it loads.

One thing I do is this, to get Unix-style line endings:
(setq-default buffer-file-coding-system 'undecided-unix)

And I do this:
(setq process-coding-system-alist
      (cons '("bash" . (raw-text-dos . raw-text-unix))
            process-coding-system-alist))

But I don't imagine that either of those is related to this.
