While reading chapter 5, Network Protocol, I discovered that
SANE_String is missing from the encoding list. I began to wonder if
it is encoded as an array (size, elem1, elem2, ...), or as a sequence
described in 4.2.5. More later.

I also discovered that SANE_Char is inconsistently defined as '8-bit
ASCII', while it in section 4.2.5 is defined as 'ISO Latin 1'
(sometime refered to as ISO 8859/1).

I assume the latter is correct, and that section 5.5.1 should be
corrected. Enclosed is my suggested change.

After reading the source (sanei_codec_bin.c), I discovered that
strings are encoded like arrays including the trailing 0. I suggest
stating that in the network chapter. I enclose a suggested patch for
this too.
