Make sure to use unsigned char for is*() functions
On some platforms, the implementation is such that a signed char
triggers a warning when used with is*() functions. On others, the
behavior is outright buggy when presented with a char that happens
to get promoted to a negative integer.
The safest thing is to cast the char that's used to an unsigned char.
