> Encodes this String into a sequence of bytes using the platform's default
> charset, storing the result into a new byte array. The behavior of this
> method when this string cannot be encoded in the default charset is
> unspecified.

> Since this is a distributed system, it is always possible that different
> nodes have different default charsets defined. I think it's most safe to
> specify it explicitly across all nodes for safety sake. You could for example
> see a situation where an upgrade JVM uses a different default and during a
> rolling upgrade of the JVM, different nodes now have a different default.
> * The default charset is usually "ISO-8859-1". UTF-8 covers more of our
> international friends.
> * Explicitly specifying the CharSet yields slight performance gains
> * Explicitly specifying the CharSet removes the need for try/catch blocks of
> UnsupportedEncodingException
