* CharacterData, though Text and others do
* inherit the interface from it. All offsets in this interface
* start from 0.
* As explained in the DOMString interface, text strings in
* the DOM are represented in UTF-16, i.e. as a sequence of 16-bit units. In
* the following, the term 16-bit units is used whenever necessary to
* indicate that indexing on CharacterData is done in 16-bit units.
