sped things up the most, and using an Entry set helped also. I'm now
just a tiny bit less of a newbie 8^)

    static String unescapeString(String inputString) {
        Set<Map.Entry<CharSequence, CharSequence>> set =
entitiesHashMap.entrySet();

        for (Map.Entry<CharSequence, CharSequence> me : set) {

It's slightly more compact just to put the 'entrySet()' call after the colon
in lieu of declaring a separate variable for it, but it does no harm to
declare the variable.

            inputString = inputString.replace(me.getKey(), me.getValue
());
        }

        return inputString;
     }

This approach creates a lot of intermediate String objects. If you use a
StringBuilder you can avoid the intermediate objects at the expense of rather
more complex code.

Unless String objects represented a huge burden, I would usually prefer the
way you did it.
