Ghostscript and CJK

:SuSE 7.2, GNU Ghostscript 5.50: Last night I tried to use KDE to print a Chinese document typed in kword to PDF. Later on I checked the PDF and only the first line was correctly displayed, other lines became all garbage. I got the same result if I print it directly from the printer. I am wondering if this is a problem of kword, the CJK support of gs or even the Chinese font (Arphic) used.
