For a given lead byte, trail bytes sort in binary order. For example, if one double-byte character has a lead-byte value of 159 and a trail-byte value of 100, and another double-byte character has a lead-byte value of 159 and a trail-byte value of 170, the character with byte values 159 and 100 sorts before the character with byte values 159 and 170, as illustrated in the following figure.
