how can i display chinese characters in qnx4? please help me

When i installed the qnx4.25,the qnx4 can not display the chinese characters,
For example,i copy a txt file which include same chinese characters to qnx4,but when i open this file with ped,it can not display anything.
And,i open the qnx help file,the chinese characters display like a big “U” .

so,how can i display chinese characters in qnx4?
how can i display chinese characters in ped and other
Applications?
install the Ph_Chinese_sup(phcn-1.10)?
Thank you
