Method

byte[]stringToUtf8Bytes(String string)
Converts a string into its Java-style UTF-8 form. 
int len = string.length();
byte[] bytes = new byte[len * 3]; 
int outAt = 0;
for (int i = 0; i < len; i++) {
    char c = string.charAt(i);
    if ((c != 0) && (c < 0x80)) {
        bytes[outAt] = (byte) c;
        outAt++;
