/**
 *  The <code>CSSCharsetRule</code> interface represents a @charset rule in a
 * CSS style sheet. The value of the <code>encoding</code> attribute does
 * not affect the encoding of text data in the DOM objects; this encoding is
 * always UTF-16. After a stylesheet is loaded, the value of the
 * <code>encoding</code> attribute is the value found in the
 * <code>@charset</code> rule. If there was no <code>@charset</code> in the
 * original document, then no <code>CSSCharsetRule</code> is created. The
 * value of the <code>encoding</code> attribute may also be used as a hint
 * for the encoding used on serialization of the style sheet.
 * <p> The value of the @charset rule (and therefore of the
 * <code>CSSCharsetRule</code>) may not correspond to the encoding the
 * document actually came in; character encoding information e.g. in an HTTP
 * header, has priority (see CSS document representation) but this is not
 * reflected in the <code>CSSCharsetRule</code>.
 * <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>.
