> The ToUnicodeWriter.writeTo(OutputStream) method converts a lot of shorts and strings to hexadecimal strings. This is done with String.format and therefore not very efficient. 
> The ToUnicodeWriter.toHex(int) and ToUnitcodeWriter.stringToHex(String) methods could be rewritten to generate a char-array and being generally more efficient.
