char casts implicitly to int, so if you really need it as an 
integer type just type your variable as such.

```d
int a = char.max; // valid.
```

If you don't need to assign it then you can cast it.

```
void a(int x) { ... }

a(cast(int)char.max);
```

Even though in the example above the cast isn't necessary, if you 
want to be sure a(int) is called then you must cast it, since an 
overload of char will obviously be picked.

The same applies for a bool.

D isn't C, so you can't really compare it 1:1, even though a lot 
of C rules apply to D, then all of them doesn't.

This is one of the places where it improves on top of it, because 
generally you don't want your min/max to be different types, but 
you can implicitly get the integer behavior if you desire so.
