While exploiting buffer overflows, we sometime face a difficulty :
character transformations. In fact, the exploited program may have modified
our buffer, by setting it to lower/upper case, or by getting rid of
non-alphanumeric characters, thus stopping the attack as our shellcode
usually can't run anymore. The transformation we are dealing here with is
the transformation of a C-type string (common zero terminated string) to a
Unicode string............................................ .............
