答案很长

• How can I detect the encoding/codepage of a text file
• Java: How to determine the correct charset encoding of a stream
• How to reliably guess the encoding between MacRoman, CP1252, Latin1, UTF-8, and ASCII
• GuessEncoding - 仅适用于UTF-8，UTF-16LE，UTF-16BE和UTF-32☹
• ICU Charset Detector
• cpdetector，免费java代码页检测
• JCharDet（Mozilla字符集检测器的Java端口） ^{_{具有讽刺意味的是，该页面无法正确呈现“Mozilla”中的撇号}}
