Not true. You don't know if
- a byte was dropped before or after 0x24
-> the first sequence is only 1 byte
- a byte was corrupted to become 0xa8
-> the sequence consists of two bytes
- a wild combination of multiple errors
With a single-unit encoding, you can always assume that an illegal unit is a one-unit error. With
any multi-unit encoding, you can only guess.
