Space is a printable character.  The C isprint(3) function says:

#include <ctype.h>
#include <stdio.h>
#include <limits.h>

int main() {
  char upper = 'a', lower = 'a';
  for(; upper < CHAR_MAX && isprint(upper + 1); ++upper);
  for(; lower > CHAR_MIN && isprint(lower - 1); --lower);
  printf("lower: %d, upper: %d\n", lower, upper);
  return 0;
}

output:

lower: 32, upper: 126
