Use this variable to point to the character map file used for translating
international character sets between machines that use differing character codes.
The map file is a simple text file that you create with an editor of your
choice. Each line in the map file must contain two values in either decimal or
hexadecimal: the character code of the character on the client machine, and the
character code of the same character on the remote machine. Use a # sign to
indicate a comment.
The runtime first searches for the configuration variable server_MAP_FILE and, if it is found, uses that setting to locate the map file. If
that variable is not set, the runtime searches for DEFAULT_MAP_FILE. If this
variable is not set, then no character translation is done. Example:
DEFAULT_MAP_FILE= c:\etc\pc_iso.txt
