A DOMString is a sequence of 16-bit units.
The UTF-16 encoding was chosen because of its widespread industry practice.
Note that for both HTML and XML, the document character set (and therefore
the notation of numeric character references) is based on UCS [ISO/IEC
10646]. A single numeric character reference in a source document may therefore
in some cases correspond to two 16-bit units in a DOMString (a high surrogate
and a low surrogate). For issues related to string comparisons, refer to String
Comparisons in the DOM.
