* data. If you neeed to transport raw binary data then consider using
* Blob and BlobBuilder.
*
* Text objects should be considered immutable. If you need to construct
* a Text object dynamically take a look at TextBuilder, and for
* serialization take a look at TextStream.
*
* A Text object is a sequence of Unicode code points. A code point is not
* one to one with a character. A single character can be represented with
* multilpe code points. In addition, a code point can also represent
* formatting or display inforamtion.
