And this macro would also work for Utf8?

I think the current understanding on the glibc side is that isdigit
could be implement as

  #define isdigit(b) ((b) >= '0' && (b) <= '9')

because isdigit recognizing alternate digits would not be compliant
with the C standard.  We just haven't got around to making the change
in the headers.
