/* Keysyms: Constants to be passed to put_key().
   These constants are equal to unicode symbols,
   except where unicode is lacking in which they are mapped to
   the application specific unicode area.
   They are functionally equivalent to but different from X11 Keysyms.

   A keysym is the value that sits on the top of a key and defines
   either the character the key produces, or the function of that key shift, up...
   In a give keyboard layout there cannot be 2 instances of the same keysym, on
   two different keys.  So multiple arrow keys need different keysyms.

   Because the characters a key produces are the most likely to change
   especailly in a dos emulator, where the other keycaps are fixed by
   what a pc keyboard can do, I have picked unicode as the character
   set of my keysyms, and am using the private space 0xE000 - 0xEFFF
   to encode the keysyms I need that are not characters.
   This encoding also facilitates in translating between character
   sets, in finding dead keys (unicode more or less already does
   that), and in getting a complete multinational keysym set produced.

Note: The range 0xEF00 to 0xEFFF is reserved as a pass through to
the current display character set.  For places where I need such a thing.
