Couchbase View query w/ Java: how to quote startkey?

package CouchbaseView;

import com.couchbase.client.CouchbaseClient;
import com.couchbase.client.protocol.views.*;

import java.net.URI;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

public class App {
    public static void main(String args[]) {
        String key = "key";
        String value = "Hello World";
        if (args.length > 0) { key = args[0]; }
        if (args.length > 1) { value = args[1]; }

        CouchbaseClient cbc;
        try {
            List<URI> baseURIs = new ArrayList<URI>();
            baseURIs.add(new URI("http://10.4.2.13:8091/pools"));

            cbc = new CouchbaseClient(baseURIs, "default", "");

        View view = cbc.getView("dev_my_app", "by_level");

        Query myQuery = new Query();
        /* This works from the shell, but how to get Java to quote OK?

$ curl 'http://10.4.2.13:8092/default/_design/my_app/_view/by_level?startkey=%5B"Level+2"%5D&endkey=%5B"Level+3"%5D'
{"total_rows":12,"rows":[
{"id":"eeeee==2222--11","key":["Level 2","ERRORED",1,"DIAPERS"],"value":12},
{"id":"wrwtwt==474--2","key":["Level 2","WAITING",1,"CPS_DEV32"],"value":12}
]
}

        I get the following output when I run the program:
        Query string '?startkey="%5B"Level+2"%5D"'
        Error testing Couchbase: java.lang.RuntimeException: Failed to access the view
        */
        myQuery.setRangeStart("%5B\"Level+2\"%5D");
        System.err.println("Query string '" + myQuery + "'");

        ViewResponse queryResults = cbc.query(view, myQuery);
        Iterator<ViewRow> walkthrough = queryResults.iterator();

        System.err.println("Found " + queryResults.size() + " docs.");
        while (walkthrough.hasNext()) {
            ViewRow row = walkthrough.next();
            System.err.println("id: " + row.getId()
                + ", info: " + row.getKey()
                + ", score: " + row.getValue()
                );
        }

            System.exit(0);
        } catch (Exception e) {
            System.err.println("Error testing Couchbase: " + e);
            System.exit(1);
        }

    }
}
