Sebb reopened CODEC-178:
------------------------

I wonder whether it is necessary to deprecate the fields.

It's not possible for Java 6 users to use the suggested alternative.
Also the replacements are anyway identical code-wise.

Once Codec requires a minimum of Java 7, I think a more helpful solution would be to redefine the constants in terms of the StandardCharsets fields, e.g.

public static final Charset US_ASCII = 
    Charset java.nio.charset.StandardCharsets.US_ASCII;

It should be possible to do this now in a static block.
i.e. try and reference StandardCharsets.US_ASCII; if this fails then revert to creating the Charset directly.

The Javadoc should probably still recommend people to use the Java 7 constants if available, but I don't see any reason to deprecate the fields given that the contents are identical.
