> * there are some places in the code that have to check for 
> UnsupportedCharsetException when explicitly using the charset name "UTF-8"
> * using StandardCharsets.UTF_8 is more efficient because the Java libs 
> usually have to look up the charsets when you provide it as String param 
> instead
> * also stop using Guava Charsets and use StandardCharsets
