public abstract class AbstractByteToChar
extends java.io.InputStream

Utility class for converting a byte stream to a character stream.

 ByteToChar converter = new ByteToChar();
 converter.setEncoding("utf-8");
 converter.clear();

 converter.addChar('H');
 converter.addByte(0xc0);
 converter.addByte(0xb8);

 String value = converter.getConvertedString();
