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
