Where to get “UTF-8” string literal in Java?

Question

I\'m trying to use a constant instead of a string literal in this piece of code:

new InputStreamReader(new FileInputStream(file), \"UTF-8\")

There are none (at least in the standard Java library). Character sets vary from platform to platform so there isn't a standard list of them in Java.

There are some 3rd party libraries which contain these constants though. One of these is Guava (Google core libraries): http://guava-libraries.googlecode.com/svn/trunk/javadoc/com/google/common/base/Charsets.html
