Checks MSB and LSB 2 bytes Korean character.
2 bytes character is bigger than ASCII Decimal code 127.
So, we can know this character is 2 byte(MSB or LSB) character or ASCII how remnant divided total length by 2.
If remnant is zero then its 2 byte character (LSB; means combined) or ASCII code.
But remnant is not a zero then its 2 byte character (MSB; means not combined), so eliminates last byte.
