I'm editing an HTML file (in emacs, of course) and want to preserve the
utf-8 encoding when the file is opened in subsequent sessions. I know I
can put a line at the top of the file which will set a variable in emacs
whenever the file is opened. So what should this line say to specify
that the file is encoded in utf-8?
Thanks.

What version of emacs are you running? Emacs 22 has much better utf-8
support than earlier versions.
The coding used/preferred by emacs is influenced by your locale
setting. If your not running a utf-8 locale, you probably will need to
set some variables (easiest via customize). What variables depends on
the version of emacs your running.
In emacs 22, if you have a utf-8 locale set, emacs will use that as its
preferred coding and you shouldn't need to do anything unless the file
has already been created in another coding system. Emacs works quite
hard to try and not change the coding used on any file it
edits. Creating a new file will use the default/preferred coding and if
you have'nt set that manually, will default to what your locale setting
is.
I do have the following in my .emacs
'(current-language-environment "UTF-8")
and a locale setting of en_AU.utf-8
Note that in emacs22 you can tell if emacs is using a utf-8 encoding by
the existance of a 'u' in the mode line (left hand side, second
character).

At the beginning of the file it would look like:
;;; -*- mode: Text; coding: utf-8; -*-
You would need to substitute the three ``;´´ with a comment
character in HTML, and you would need to leave away the ``mode: Text;
´´ part or substitute it with the proper mode.

If you're using HTML mode, just specifying
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
in the head element of the file should do it.
Otherwise, a generic method for specifying the coding to emacs is
having -*- coding: utf-8 -*- in the first line of the file. You should
typically protect that by putting in a comment, as follows:
<!-- -*- coding: utf-8 -*- -->

Thanks, Harald and Peter,
The above is perfect. On to the subsequent issue....
Prior to doing the above I somehow managed to figure out how to insert a
word in Greek into my HTML file and have it display properly both in
emacs and in the web browser. (This required (1) setting the keyboard
for inputting Greek and (2) setting some emacs display variable, which I
no longer recall, also to Greek.) Though both the Greek and the English
displayed correctly in emacs when first typed in, after reloading the
file specifying utf-8, the Greek characters now display in emacs as a
series of little rectangles. (They still display fine in the web browser.)
Is there another variable:value pair I can include in the first line
(specified above) to make the Greek characters display correctly in emacs?
Much appreciated.

No, not that easily (there were rich or augmented text modes
mentioned on this list, but I don't remember). The problem you have
in GNU Emacs is that you either need a (mono-spaced) font that has
Latin and Greek glyphs (xfd can display a font's contents, you could
also set for xfontsel a sampleTextUCS resource that combines Greek
and some Latin to instantly show whether the chosen font is able to
display it, you also can use fc-list to display only fonts that have
Greek support: 'fc-list :lang=el', the "word" ``el´´ is from RFC-3066/
ISO 639, which you should know as HTML programmer) or you need to
setup a fontset in which you combine font A to serve for Latin and
font B to serve for Greek (and font C for Indic ...). Something like
this might work (for one font size):
(create-fontset-from-fontset-spec "-adobe-courier-medium-r-*-*-9-
*-*-*-*-*-fontset-09pt_adobe_courier" t 'noerror)
(set-fontset-font "fontset-09pt_adobe_courier" 'latin-

Peter,
Thanks, but that didn't work.
I cut-n-pasted the code you provided into its own file. Then I ran
emacs -q -l emacs.d/.emacs-with-multi-langs &
(emacs.d/.emacs-with-multi-langs is the file your code went into.)
Then I opened up (visited) my file with the Greek chars in it and they
showed up as what I can only describe as "garbage" characters, not even
the blocks I had before and certainly nothing like Greek.
On an optimistic note, running "fc-list :lang=el" returned 86 lines of
fonts, many with multiple styles. And
$ fc-list :lang=el|grep -i "courier new"
Courier
New:style=Regular,Normal,obyčejné,Standard,Κανονικά,Normaali,Normál,Normale,Standaard,Normalny,Обычный,Normálne,Navadno,thường,Arrunta
Courier New:style=Bold Italic,Negreta cursiva,tučné kurzíva,fed
kursiv,Fett Kursiv,Έντονα Πλάγια,Negrita Cursiva,Lihavoitu Kursivoi,Gras
Italique,Félkövér dőlt,Grassetto Corsivo,Vet Cursief,Halvfet
Kursiv,Pogrubiona kursywa,Negrito Itálico,Полужирный Курсив,Tučná
kurzíva,Fet Kursiv,Kalın İtalik,Krepko poševno,Lodi etzana
Courier
New:style=Italic,Cursiva,kurzíva,kursiv,Πλάγια,Kursivoitu,Italique,Dőlt,Corsivo,Cursief,Kursywa,Itálico,Курсив,İtalik,Poševno,nghiêng,Etzana
Courier
New:style=Bold,Negreta,tučné,fed,Fett,Έντονα,Negrita,Lihavoitu,Gras,Félkövér,Grassetto,Vet,Halvfet,Pogrubiony,Negrito,Полужирный,Fet,Kalın,Krepko,đậm,Lodia
(Line wrap broke the lines above between "Courier" and "New".)
So would it fix things to change somehow this line in your code:
(set-fontset-font "fontset-09pt_adobe_courier" (cons (decode-char 'ucs
#x0370) (decode-char 'ucs #x03cf)) '("courier new" . "iso10646-1")) ;
Greek
??
Thanks again.

It might. Check with xfd (or fontforge or ...) that the font contains
what it claims! The important thing is that you need to make the
frame with its buffers use that fontset. If it exists just an option,
then nothing changes for you. And you can also use a different font
size. Some possible settings:
(setq initial-frame-alist '(
(border-color . "#4e3832")
(foreground-color . "grey10")
(background-color . "AliceBlue")
(active-alpha . 0.875)
(inactive-alpha . 0.75)
(font . "fontset-10pt_lucidatypewriter")
(top . 5) (left . 500) (width . 106) (height . 50)
)
)
There is also default-frame-alist.
