Thanks for getting back to me promptly. I can understand now why wc
increasing it by one but it is obviously, the explanation you gave me
should be documented in man page or info page, agreed? Thanks.

The newline on the end of the line is a character.  You can see this
by using od to dump the values.

  echo 1234 | od -tx1 -c
  0000000 31 32 33 34 0a
            1   2   3   4  \n

Of course wc is behaving correctly here.
