Don't confuse the character set that the program can manipulate,
with the character set that it is written in.
An Ada program on an EBCDIC machine would manipulate a non-EBCDIC
representation of characters, but it might have been typed up in
EBCDIC to be compiled.
The type Character is an enumeration (of character literals),
representing each character with a specified code.
My 83 Rationale isn't handy. I'd guess Character was defined this
way specifically so that data would easily interchange between
Ada programs, and so the programmer could reason about the
ordering of the characters (e.g., digits are in the range 0 .. 9).
Best,
Sam Mize
