[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.
