The last is preferable.

The ISO C standard specifies is* facilities operate properly on
all values representable as type `char' and type `unsigned char'.
It depends on implementation whether char is signed or unsigned. 
The is* facilities should operate on range [-128,256] on the
implementation where char is singied.
