// the unshift sequence causes the state to be reset.
|

//
|
|
// The conversion for output is as follows:
|
|
// 1. Calculate the value tmp by xor-ing the state and the internal
|
|
// character
|
|
// 2. Split tmp into either two or three bytes depending on the value of
|
|
// state. Output those bytes.
|
|
// 3. tmp becomes the new value of state.
