Looks fine to me.

Out of curiousity, do we need classes ASCII and UTF8 and their methods?
Would it be enough to have

    public static final Charset ASCIIcharset = Charset.forName("US-ASCII");
    public static final Charset UTF8charset = Charset.forName("UTF-8");

somewhere, and then tame Charset, allowing the rest of the methods to
be implemented in Joe-E rather than in trusted Joe-E libraries?  This is
a tangent, not an objection to adopting these libraries, so please don't
let it stop you from adopting these proposed implementations; I'm just
curious.
