public class BOMInputStream extends InputStream
读取带BOM头的流内容，getCharset()方法调用后会得到BOM头的编码，且会去除BOM头 BOM定义：http://www.unicode.org/unicode/faq/utf_bom.html
  • 00 00 FE FF = UTF-32, big-endian
  • FF FE 00 00 = UTF-32, little-endian
  • EF BB BF = UTF-8
  • FE FF = UTF-16, big-endian
  • FF FE = UTF-16, little-endian
使用： String enc = "UTF-8"; // or NULL to use systemdefault FileInputStream fis = new FileInputStream(file); BOMInputStream uin = new BOMInputStream(fis, enc); enc = uin.getCharset(); // check and skip possible BOM bytes
