Long answer to my mostly-rhetorical question, but I'll follow up:
To restate my answer, then: The original problem stems from using the
character 147 (hex 0x93) in a file that's *not* encoded in CP1252 (which
is the default on American Windows machines, and might be what you'd get
from 'ASCII' on such a machine with a naïve editor/browser) *or* in a
Vim that's not expecting CP1252 data. By default [even on Windows?], I
think Vim expects UTF-8 (one way to encode Unicode) data.
For the setting that controls the former, see :help 'fileencoding'. For
the latter, :help 'encoding'.
The 'ÿ', it turns out, is actually character 255 (the maximum allowed
decimal entry):
See :help i_CTRL-V_digit (as someone else pointed out).
As I stated before, 8220 is the decimal equivalent of the Unicode point
U201C, which apparently can't be entered *in decimal* in vanilla Vim.
You can use the hexadecimal version, though.
e.g., to search for an opening 'curly double quote':
/ <C-v> u 2 0 1 c <Enter>
For more on encodings in general:
For a non-Vim explanation: http://en.wikipedia.org/wiki/Windows-1252
For a somewhat tongue-in-cheek, programming oriented take:
http://www.joelonsoftware.com/articles/Unicode.html
For more, I think my answer and others give you some keywords for
searching: character encodings, Latin 1, Unicode, CP 1252, multibyte,
ASCII.
