Strange.  What happens if you put (set-language-environment "utf-8")
into ~/.emacs?  Is there an error message?

That's how it is supposed to be.

What does M-x describe-coding-system RET RET say when in the shell
buffer?  The codings for process i/o should be utf-8.  As a
workaround, you could try M-: (set-process-coding-system nil 'utf-8
'utf-8) RET from the *shell* buffer.

That's also strange -- my Emacs defaulted to Latin-9 when I did this.
Maybe it was a font problem?  I had set "Emacs.font:
yadda-yadda-iso8859-15" originally, but had to revert to "Emacs.font:
yadda-yadda-iso8859-1" to get the right behavior.
