Subject: [PATCH] Fix calling utf8_in2

utf8_in2, when working in backward mode, is assuming that we are giving
the address of the last byte of the previous character (see all other
calls to utf8_in2). Otherwise, utf8_in2 returns the size of the current
multibyte character instead of that of the previous multibyte character.
