I'm afraid I don't understand why this is needed. The position of the
incomplete UTF-8 character is easy to find. Start at the end of the byte
string and look backwards until you find a byte that has both the 0xc0
bits set. That is the first byte of the incomplete UTF-8 character.
Putting something other than a match start into the offsets vector
rather breaks the philosophy of PCRE.
