 package com.google.common.base;
 
 
Contains constant definitions for the six standard java.nio.charset.Charset instances, which are guaranteed to be supported by all Java platform implementations.

Assuming you're free to choose, note that UTF_8 is widely preferred.

See the Guava User Guide article on Charsets.
