How can I set up emacs so it will open and save files in utf-8 coding system?

   export LANG=foo_BAR.utf-8

I.e. set your locale.

(set-language-environment "UTF-8") if you use Emacs 21.3 or CVS Emacs.
Probably you can also use `prefer-coding-system' and friends, see the
manual for details:

(info "(emacs)Recognize Coding")
(info "(emacs)Language Environments")

I.
What's the difference between (set-language-environment "UTF-8") and
putting something like form below in .emacs? :

(custom-set-variables
   '(case-fold-search t)
   '(current-language-environment "UTF-8")
   '(default-input-method "latin-4-postfix"))

....

II. Related question:

I want to add upper and lower case y with macron to the
\leim\quail\latin-post.el code. I know that the cardo.ttf font has the
glyphs and I think that micross.ttf (Microsoft Sans Serif) has them. The
code points are U+0232 and U+0233 but I don't know how to insert these
characters into the lisp code. Can I specify a hex value in some format
in this context? Do I also need a specific cp_*.nls code page file
registered in MS Windows in order to get this to work?

Thanks,

Ed

How about reading the manual node that I have posted above?  ;-) Both
methods are equivalent:

,----[ (info "(emacs)Language Environments") ]

AFAIK, the input methods are not well documented.  But it should work
like this:

--8<---------------cut here---------------start------------->8---
(when (and (load "quail/latin-post" t)
	   ;; side effect: also change the default input method:
	   (setq default-input-method "latin-4-postfix"))
  (quail-defrule "Y-" (decode-char 'ucs #x0232) "latin-4-postfix")
  (quail-defrule "y-" (decode-char 'ucs #x0233) "latin-4-postfix"))
--8<---------------cut here---------------end--------------->8---

Let's test it: `Y -' ==> Ȳ, and `y -' ==> ȳ.  Seem to work for me.

BTW: Using the TeX input method, you can get the characters
with `\ = Y' and `\ = y'.

The thread with the subject "Unicode literals" in comp.emacs might
also be of interest for you:

Which node I turned to only after posting the above. Sorry. Greenhorn
here.

I assume that this can be added to my .emacs or evaluated in a lisp
buffer. I will try both. Although I have been warned against it I would
like to make the changes directly to the latin-post.el. Could I get away
with something like:

(quail-define-rules
[...]

 ("Y-" ?#x0232)  ;;; I tried to copy paste these but they were corrupted
by Outlook Express. (Maybe it's "\x0233" or some other combination
 ("y-" ?#x0233)   ;;; of slashes, hashes, or single or double quotes)

[...]

Thanks. I did read this since I knew it was pertinent to my problem but
I understood dimly if at all.

I wouldn't recommend this neither.
