/* One of the problems that arises when testing character constants

is that of definition: What, exactly, is the character set?

In order to guarantee a certain amount of machine independence,
|
|
the character set we will use here is the set of characters writ-
|
|
able as escape sequences in C, plus those characters used in writ-
|
|
ing C programs, i.e.,
|
|
|
|
letters:
|
|
ABCDEFGHIJKLMNOPQRSTUVWXYZ 26
|
|
abcdefghijklmnopqrstuvwxyz 26
|
|
numbers:
|
|
0123456789 10
|
|
special characters:
|
|
~!"#%&()_=-^|{}[]+;*:<>,.?/ 27
|
|
extra special characters:
|
|
newline \n
|
|
horizontal tab \t
|
|
backspace \b
|
|
carriage return \r
|
|
form feed \f
|
|
backslash \\
|
|
single quote \' 7
|
|
blank & NUL 2
|
|
---
|
|
98

Any specific implementation of C may of course support additional

|
characters. */
