debian emacs 22.2.1 why do greek and hebrew fonts display normally with -nw and not in an xwindow

[shul]

Hi I have an utf8 encoded file with some greek characters and it looks
like "square boxes" when it  opens in
with
emacs 3.pl
while it looks fine with
emacs -nw 3.pl.

If you want to look at the files. I downloaded them  from

http://www.ibm.com/developerworks/linux/library/l-cpunicode/index.html
cp35.zip

What is wrong with my  setup. What can I do so that the characters
will display in both the x windows and term version of emacs?
