I appreciate the reply and the detailed explanation. Unfortunately,
running the Carbon version of Emacs under Mac OS X does not help. The
problem is that for some reason Emacs/Carbon can not see any iso10646-1
fonts. Although I have fixed width fonts like 'andale mono' which
support WGL4 and which I have used before under Linux with encoding
iso10646-1, Emacs says that they are available only with encoding
mac-roman. Also the etl-* fonts which are the GNU intlfonts converted
for use with Macs do not have the iso10646-1 encoding (but at least
they have the iso8859-7 encoding). So basically I do not know how to
proceed from here using the Carbon Emacs. In principle I can run the
X11 version of Emacs but I prefer the Carbon version for many reasons.

Uh, sorry. I don't know anything about Mac OS. So I can't help you
here. Basically you just need to find a font encoded in ISO 10646
which contains the necessary characters from the "Greek and Coptic"
repertoire.
But I don't know how to find such a font on Mac OS.

I see. It is a font problem. You need to create a fontset in order to
solve it. Look for an appropriate ISO 10646-1 font and set Emacs up to
use it for the charset mule-unicode-0100-24ff. For example this should
work on GNU/Linux:
(create-fontset-from-fontset-spec "\
-b&h-lucidatypewriter-medium-r-*-*-14-*-*-*-*-*-fontset-konstantinos,\
latin-iso8859-15:-b&h-lucidatypewriter-medium-r-*-*-14-*-*-*-*-*-iso8859-1,\
mule-unicode-0100-24ff:-*-fixed-medium-r-*-*-14-*-*-*-*-*-iso10646-1")
(set-face-font 'default "fontset-konstantinos")
Maybe there is a ISO 10646 variant of the ETL font that you are using?
Some people prefer to do it via X-ressources, but I don't use that and
I am too lazy to look the syntax up in the manual.
What is happening? Emacs internal encoding (emacs-mule) is divided
into several so-called "charsets". Every character in a buffer belongs
to a charset and some charsets contain the same (abstract)
characters. The Greek input method you use obviously inserts chars
from `greek-iso8859-7'. (Some or all (?) of the input methods for
classical Greek, for example, use `mule-unicode-0100-24ff'.) Font
resolving and similar things depend on those charsets. When you save
the file as UTF-8, then Emacs knows how to generate the appropriate
UTF-8 octets for the charset `greek-iso8859-7'. But when you visit it
again, then Emacs does not decode those UTF-8 octets to characters
belonging to `greek-iso8859-7', but to chars from
`mule-unicode-0100-24ff'. This is actually a good thing. It's just a
font issue that you don't see the right glyphs for those characters.

Please move the cursor to one of those characters that should appear
as a Greek char, but doesn't. Then press `C-u x =' and post the
output.

As a side question, how would I find out what function is bound to
that key sequence? If I type M-x describe-key, followed by C-u, all I
get is the definition of the command universal-argument.

You should type "M-x describe-key RET C-x =", and in the doc string
look for the description of how a numeric argument changes the
behavior of that key. C-u simply supplies a numeric argument to the
command invoked immediately after it. See the node "Arguments" in the
Emacs manual for more details.

[...]
The function is bound to `C-x ='. If you hit `C-u', Emacs passes a
prefix to this function (i.e. a specific argument specified by the
function's `interactive' declaration is non-nil). The help for that
function (`C-h k C-x =' in this case) should tell you what it does for
which kind of prefixes (if any).

It seems that emacs can not display properly a text file with UTF-8
encoding. Specifically, I do the following:
(1) Create a new buffer with UTF-8 encoding: C-x C-f test.txt
(2) Change the input method to greek: C-u C-\ greek
(3) Write some characters. Everything appears perfectly.
(4) Toggle the input method: C-\
(5) Save the file: C-x C-s
(6) Open the file: C-x C-f test.txt
Now all the greek characters appear as squares.
I am using GNU Emacs 21.3.50.1 (powerpc-apple-darwin7.0.0) under Mac OS
X 10.3. When I open the file with TextEdit using the UTF-8 encoding and
everything looks fine in there.
In my .emacs I have
(set-language-environment 'greek)
(set-default-coding-systems 'utf-8)
(prefer-coding-system 'utf-8)
Note also that if I set the proper variables for using iso-8859-7
everything works great.
