Hi Will. I decided to respond because of this observation in the latest posting: "They used to say emacs and vi are religions; these days they are starting to seem like latin."

I want to always use Unicode/UTF-8 unless otherwise specified.  I've noticed
that I've attempted to do this in my .emacs file in two separate ways on two
separate platforms:

1)  (setq-default buffer-file-coding-system 'utf-8-unix)

2)  (set-language-environment "UTF-8")

Both seem to work, but I'm wondering if there are subtle differences between
the two that I should be aware of.

I can't help with any subtlties but can only recommend that you add this cookie to the beginning of the buffer:

 ;; -*- coding: utf-8 -*-

I think it may be enough to save and reload the file into a new buffer before adding exotic characters.
I also have these lines in my .emacs:

  (set-locale-environment   "utf-8")
        (set-language-environment               'utf-8)
        (set-default-coding-systems             'utf-8)
        (setq file-name-coding-system           'utf-8)
        (setq buffer-file-coding-system 'utf-8)
        (setq coding-system-for-write           'utf-8)
        (set-keyboard-coding-system             'utf-8)
        (set-terminal-coding-system          'utf-8)
        (prefer-coding-system                   'utf-8)
        ;; (set-buffer-process-coding-system 'utf-8 'utf-8)
(modify-coding-system-alist 'process "[cC][mM][dD][pP][rR][oO][xX][yY]" 'utf-8-dos)

The line commented out caused a problem but I don't remember what it was. My os w64 vers. 7
