Method

byte[]stringToByteArray(String str, Charset charsetForEncoding, int lenOfByteArray, byte filler)
Converts the given String into a byte array of given length using the given Charset for encoding. 
if (charsetForEncoding == null)
    charsetForEncoding = Charset.defaultCharset();
byte[] encoded = str != null && str.length() > 0 ? str.getBytes(charsetForEncoding) : new byte[] {};
byte[] result = new byte[lenOfByteArray];
for (int i = 0; i < lenOfByteArray; i++) {
    if (i < encoded.length) {
        result[i] = encoded[i];
    } else {
...
byte[]toBytes(CharSequence str, String charsetName)
