[httpd]AddDefaultCharset이 바뀌니까 사이트가 안뜨네요

현재까지 구동 시키던 사이트가
httpd.conf 환경파일에
AddDefaultCharset = EUC-KR 이였습니다.
그런데 FCKeditor이라는것이
UTF-8로만 돌아가더라구요 그래서 UTF-8로 변경을 했더니 기존 사이트가 안돌아 갑니다.

이럴떄 둘다 돌아가게 하려면 어떻게 해야 하나요?

현재 문자관련 세팅은 아래와 같습니다.

#
# Specify a default charset for all pages sent out. This is
# always a good idea and opens the door for future internationalisation
# of your web site, should you ever want it. Specifying it as
# a default does little harm; as the standard dictates that a page
# is in iso-8859-1 (latin1) unless specified otherwise i.e. you
# are merely stating the obvious. There are also some security
# reasons in browsers, related to javascript and URL parsing
# which encourage you to always set a default char set.

AddDefaultCharset euc-kr
#
# Commonly used filename extensions to character sets. You probably
# want to avoid clashes with the language extensions, unless you
# are good at carefully testing your setup after each change.
# See http://www.iana.org/assignments/character-sets for the
# official list of charset names and their respective RFCs.
