I have a program written in C runing on Solaris 9 (ANSI). It uses a socket to listen for new data from Tcl client. There is no GUI for this program. All it does is to parse data received from the client and write it to an xml file. Now I'd like to convert the program to accommodate Japanese/Chinese characters. What I need to do for this purpose?
Is there any reference or good tutorial on software internationalization for C (Unix)?
Any help on this is greatly appreciated.
