[t_liang]

System.out.println(BinaryCodec.toAsciiString(new byte[] { 'a' })); // output 
01100001 System.out.println(BinaryCodec.toAsciiString(new byte[] { 'b' })); // 
output 01100010 System.out.println(BinaryCodec.toAsciiString(new byte[] { 'a', 
'b' })); // output 0110001001100001(ba), why not 0110000101100010(ab)?
