[Sbcl-help] Encoding issue

[jcm@SDF.ORG]

I'm using this article as a jumping off point to deploy hunchentoot as a
service:

http://zaries.wordpress.com/2010/11/09/lisp-web-server-from-scratch-using-hunchentoot-and-nginx/

But I'm having an encoding issue.  When I start this app from my personal
account, or even the system user that is used by the
'/etc/init.d/hunchentoot start' script, everything works fine.

However, when I start hunchentoot as a server, and attempt to output one
particular name via db query and xml output, I get this:


4: ((FLET #:LAMBDA769)
    #<TYPE-ERROR
      expected-type: BASE-CHAR datum: #\LATIN_CAPITAL_LETTER_A_WITH_TILDE>)
.
.
.
15: (REPLACE "JIM" "JIMÉNEZ, ANGELA")
16: (XML-EMITTER::WRITE-ESCAPED
     "JIMÉNEZ, ANGELA"
     #<SB-IMPL::STRING-OUTPUT-STREAM {CD0D891}>)
17: (XML-EMITTER:SIMPLE-TAG "opt" "JIMÉNEZ, ANGELA" (("val" 783)) NIL)

Even though this form:

(format t "Encoding~%")
(format t "~A~%" (sb-impl::default-external-format))

Outputs:

Encoding
UTF-8

because I have this:

LC_CTYPE=en_US.UTF-8; export LC_CTYPE

in the 'start-hunchentoot' script called by the /etc/init.d/hunchentoot
script.

What other encoding settings should I check to figure out the discrepancy?
