I assume that this is Java code and not C code. Is that right?
Are you sure that you posted your code correctly? When I try what
you've done, I get an IndexOutOfBoundsException when executing
sZero.charAt(1), which is what I would expect.
Also, are you sure you're getting 65533 and not 65535? If you convert
a value of -1 to an unsigned 16-bit integer, you get 65535. If you
don't understand why, search the web for how negative integers are
stored at the bit level. So, this might be related.
Also, it sounds like you want to control things at the byte level. If
so, you probably want to use the "byte" data type and stay away from
char and int and String. Don't think of a String as an array of
bytes, because it's not (in Java). It's more list a list of
"characters" WHERE each "character" might actually take up more than
one byte because of internationalization support.
So perhaps you should be working with "byte" instead of "char",
assuming you're trying to manipulate things at the byte level.
