Picking up the Bible (K&R) and quoting without permission from page 17

Any single character can be written between single quotes, to produce
a value equal to the numerical value of the character in the machine's
character set; this is called a {\it character constant}. So, for
example, 'A' is a character constant; in teh ASCII character set its
value is 65, the internal representation of the character A.

and page 35 says

A {\it character constant\/} is a single character written within
single quotes, as in 'x'.
