No, I was thinking of something a little more sophisticated than that. Classes of strings would be sub-classed from others like English would have multiple sub-classes like American, British etc. Each class could have it's own parameters like whether it supports being reversed. You would not necessarily implement just for English. If you were making a palindrome finding app for example, you would only care if the class passed in supports reversing for example. Eventually you could have a language DB library, not so different that the time zone database that can be periodically updated with new rules.
