- A state machine to verify a byte sequence for a particular encoding. For
- each byte the detector receives, it will feed that byte to every active
- state machine available, one byte at a time. The state machine changes its
- state based on its previous state and the byte it receives. There are 3
- states in a state machine that are of interest to an auto-detector:
-
- START state: This is the state to start with, or a legal byte sequence
- (i.e. a valid code point) for character has been identified.
-
- ME state: This indicates that the state machine identified a byte sequence
- that is specific to the charset it is designed for and that
- there is no other possible encoding which can contain this byte
- sequence. This will to lead to an immediate positive answer for
- the detector.
-
- ERROR state: This indicates the state machine identified an illegal byte
- sequence for that encoding. This will lead to an immediate
- negative answer for this encoding. Detector will exclude this
- encoding from consideration from here on.
