Sorry... I can't write in Korean. 
 I installed RedHat7.2 English, but installed with Korean Language pack. And, opera 6.0 beta1 for linux, Redhat RPM 7.2
o Qt dynamically linked (RPM for RedHat 7.1, Mandrake 8, 2.78 MB)
 I only can see Korean via Opera. I got some help from this board, so I will write some simple tips.
 1. see
http://linux.sarang.net/board/?p=read&table=tip&no=5333&page=&o[at]=s&o[sc]=t&o[ss]=efont&o[st]=a
 also it would be helpful: (but do not do this)
http://soback.kornet.net/~geyhsung/nxop6tp2.html  2. more explanation:
 - in my case, (Redhat7.2) /usr/X11R6/lib/X11/fonts/misc is the font directory.
 - first, download this to any temporary directory:
http://openlab.ring.gr.jp/efont/dist/unicode-bdf/efont-unicode-bdf-0.4.0.tar.bz2  - secondly, do this
tar xvIf efont-unicode-bdf-0.4.0.tar.bz2
 - thirdly, open an editor (like gedit or ...) then insert this
#!/bin/sh
for file in *.bdf
do
result=`basename $file .bdf`.pcf
bdftopcf -o $result $file
done
- and save as bdf2pcf
- then do this
chmod 755 bdf2pcf
- also do this
./bdf2pcf
- then, do this
gzip b*.pcf
- then, do this
mv b*.gz /usr/X11R6/lib/X11/fonts/misc/
 - move to that directory
cd /usr/X11R6/lib/X11/fonts/misc
- then, open /usr/X11R6/lib/X11/fonts/misc/fonts.alias
- and add below to the end of the file <WARNING>: copy below as it is, actually, one line has two strings: unifont is th
e former, biwidth is the latter, separated by a space. -efont-unifont-medium-r-normal--12-120-75-75-p-60-iso10646-1 -efo
