Explicitly use UTF-8 when turning strings to byte arrays

For peace of mind, I'd like to specify that the UTF-8 encoding is used every time a string is turned into a byte array.

I only left the original getBytes() calls in some unit tests where UTF-8 conversions were unnecessary, as when dealing with Base32 or Base64 data, or when using it to generate a crypto key for testing purposes with a fixed string.

You can use StringUtils.getBytesUsAscii which already convert the exception to
runtime exception.

Maybe use StringUtils.getBytesUtf8 instead which already convert the exception
for you (an probably in many other places)
