Synopsis:
   set display_pc_characters [0|1|2|3|4|5]

Description:
   This setting controls how epic displays characters with the high bit 
   set ("Eight-bit characters").

   Some terminal emulators support a "graphics mode" where all characters 
   are printable, even control characters.  The DOS console is an example.
   These terminals are called "graphics terminal".  This is important later.

A Side Note:
   Every character that is put to your display is categorized into one of
   nine categories:

       0 - A normal, printable 7-bit character
       1 - Any character with the high bit set ("8-bit character")
       2 - The escape character (^[)
       3 - The color code character (^C)
       4 - An Attribute Change character (^B, ^F, ^_, ^V, etc)
       5 - A "suppressed" character (if SET ALLOW_C1_CHARACTERS is OFF then
                                     128 <= x <= 159 are suppressed)
       6 - Any other "control" character (0 <= x < 32)

   Category 5 characters are always removed.
   Category 6 characters are accepted if you're using a "graphics terminal"
      otherwise 32 is added to the character and printed in reverse.

Now back to the story:
   Category 1 characters are mangled according to this set's value:
      0 - The character is stripped
      1 - The character is allowed if /SET EIGHT_BIT_CHARACTERS is ON
          The character is mangled in reverse if /SET EIGHT_BIT is OFF.
      2 - The character is allowed on a "graphics terminal"
          The character is translated in reverse if not a graphics terminal.
      3 - The character is allowed on a "graphics terminal"
          The character is translated if not a graphics terminal.
      4 - The character is allowed
      5 - The character is translated

   In this case, "mangled" means the high bit is removed (making it a 7-bit
   character) and the 5th bit is set (making it printable).  The result is a
   character in the range 64 <= x <= 127.

   Also, "translated" means the character is replaced with another character
   which may pose an unreasonable approximation to the original.  This
   translation is hardcoded into epic, and perhaps will be customizable in
   the future.
