The C code works fine, the sse2 and 64 bits sse2 it is of the problem
with Unicode or other multibyte encoding. In the first step i use an
optimization using a shift in place of a rotation (the gain is very
small but it is a gain :) ). Tecnically it is not a bug as the code
was designed to work with byte enconding and not multibyte. When i
have some time i change that, with other stuff that i later comment on
the list.
