> String/byte conversions may take either a Charset instance or its canonical name. One
might think a Charset instance would be faster due to avoiding a lookup and instantiation
of a Charset, but it's not. The canonical string name variants will cache the string encoder/decoder
(obtained from a Charset) resulting in better performance.
