An actual pointer you can't but it looks like the pointer you're
referring to is just an index so yes you can use a char but most
compilers are going to promote a char to an integer when doing
arithmetic. You can sometimes override the promotion but it can get
ugly. Usually you need to add "& 0xff" and char casts to do this.
