integer->char[procedure] integer->char n
R5RS: Converts an exact integer n to the corresponding character.
The mapping between integers and characters is implementation-dependent.
Furthermore, when n is outside of the range of char->integer,
what happens depends on the implementation.
R6RS: Converts an Unicode scalar value n to the corresponding
character. Thus, n must be in the range between 0 and #xd7ff or
#xe000 and #x10ffff. If other value is given, &assertion?
exception will be raised.
