Actually, a lot of document are flagged as iso latin 1 so
even a small improvement in that area is not neglectable !
One possible optimization is to fetch/test/save for ASCII data
on 32bits chunks, doing an AND with 0x80808080, one just need to
to take more care for the beginning and end of the segment to test
since unaligned accesses on 32 bits values would be a bummer.
