## Interface CSSCharsetRule

- All Superinterfaces:
    `CSSRule`

      public interface CSSCharsetRule
      extends CSSRule

  The `CSSCharsetRule` interface represents a @charset rule in a CSS style sheet. The value of the `encoding` 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 `encoding` attribute is the value found in the `@charset` rule. If there was no `@charset` in the original document, then no `CSSCharsetRule` is created. The value of the `encoding` attribute may also be used as a hint for the encoding used on serialization of the style sheet.

  The value of the @charset rule (and therefore of the `CSSCharsetRule`) 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 `CSSCharsetRule`.

  See also the Document Object Model (DOM) Level 2 Style Specification.

  Since:
    1.4, DOM Level 2
