Because text is a high-order abstraction.  You don't store text in files, you don't transmit text over the wire or 
through the air -- those actions are done with a lower abstraction, that of bytes.

You're framework may allow you to add a string, but under the covers it's converting to bytes -- at which point is up to 
the framework.
