-/**
- * Generic unicode text reader, which will use BOM mark to identify the encoding to be used. If BOM is not found then
- * use a given default encoding. UTF-8 is used if: BOM mark is not found and defaultEnc is NULL. Usage pattern:
- *
- * <pre>
- * String defaultEnc = "UTF-16BE"; // or NULL to use system default
- * FileInputStream fis = new FileInputStream(file);
- * Reader in = new UnicodeReader(fis, defaultEnc);
- * 
- * Original pseudocode   : Thomas Weidenfeller
- * Implementation tweaked: Aki Nieminen
- *
- * http://www.unicode.org/unicode/faq/utf_bom.html
- * BOMs:
- * 00 00 FE FF    = UTF-32, big-endian
- * FF FE 00 00    = UTF-32, little-endian
- * FE FF          = UTF-16, big-endian
- * FF FE          = UTF-16, little-endian
- * EF BB BF       = UTF-8
- *
- * Win2k Notepad:
- * Unicode format = UTF-16LE
- * </pre>
