Class UnicodeReader

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable, java.lang.Readable

    public class UnicodeReader
    extends java.io.Reader
    Generic unicode textreader, which will use BOM mark to identify the encoding to be used. If BOM is not found then use a given default encoding. System default is used if: BOM mark is not found and defaultEnc is NULL

    Usage pattern: String defaultEnc = "ISO-8859-1"; // or NULL to use system default FileInputStream fis = new FileInputStream(file); Reader in = new UnicodeReader(fis, defaultEnc);
