  17 /**
  18  *  The <code>CSSCharsetRule</code> interface represents a @charset rule in a
  19  * CSS style sheet. The value of the <code>encoding</code> attribute does
  20  * not affect the encoding of text data in the DOM objects; this encoding is
  21  * always UTF-16. After a stylesheet is loaded, the value of the
  22  * <code>encoding</code> attribute is the value found in the
  23  * <code>@charset</code> rule. If there was no <code>@charset</code> in the
  24  * original document, then no <code>CSSCharsetRule</code> is created. The
  25  * value of the <code>encoding</code> attribute may also be used as a hint
  26  * for the encoding used on serialization of the style sheet.
  27  * <p> The value of the @charset rule (and therefore of the
  28  * <code>CSSCharsetRule</code>) may not correspond to the encoding the
  29  * document actually came in; character encoding information e.g. in an HTTP
  30  * header, has priority (see CSS document representation) but this is not
  31  * reflected in the <code>CSSCharsetRule</code>.
  32  * <p>See also the <a href='http://www.w3.org/TR/2000/REC-DOM-Level-2-Style-20001113'>Document Object Model (DOM) Level 2 Style Specification</a>.
