intlchar.c sample program

The intlchar.c sample program demonstrates Open Server's handling of national languages and character sets. It initializes values for the Open Server application's national language and character set, and then changes these values in response to client requests.

Client requests come in the form of option commands and language commands. intlchar.c installs SRV_OPTION and SRV_LANGUAGE event handlers, as well as a SRV_CONNECT handler.
