Just found out from my Singapore friend trying out the script on Solaris 8:
"gd news... after i install the langpack for solaris 8 come with the kits. now able to display correctly liao. i have install the solaris 8 lang pack last week ago. i just follow the CD installation step. install all the asian lang"
So looks like I need to get with the SA's and have them install asian language fonts for Redhat and each Solaris OS.
Will let you know if that takes care of all the problems.
