detect_utf8_character: logic error

I think for the "compute character number" the "...0x3F) < 6)" here should have been a left bit shift "...0x3F) << 6)"

        else {
            unicode_len = 4;
            /* compute character number */
            d = ((c & 0x07) << 18) | ((*(p_read + 1) & 0x3F) << 12) | ((*(p_read + 2) & 0x3F) < 6) | (*(p_read + 3) & 0x3F);
        }

Apologies if I'm mistaken

FYI that might also be present in v3 here

Fixed! Thanks!
