libguess: libguess (A high-speed character set detection library)
libguess:
libguess: libguess employs discrete-finite automata to deduce the character 
libguess: set of the input buffer. The advantage of this is that all character 
libguess: sets can be checked in parallel, and quickly. Right now, libguess 
libguess: passes a byte to each DFA on the same pass, meaning that the winning 
libguess: character set can be deduced as efficiently as possible.
