Java porting Mozilla's Code Auto-detection library (source code for C + +), accurate rate is high.

Can be combined with another Java character Set detection library to ensure better results, because for the short passage, the above detection method may not be able to draw conclusions.

At the same time, because this algorithm comes from Mozilla, it should be better for the detection of HTML and other label files.
