Model object string manipulation

What's the cleanest way of doing string manipulation with a component that uses a String as a model (e.g. a Label). I'm thinking of mutations such as to uppercase and to lowercase, etc. An obvious place is to do it in the model, but I'm interested to hear what other developer's approaches are.
