> 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.
