 * When the document is read in a converter is used to convert 
 * the document's data to Unicode.
 *
 * nsIDocCharset provides the ability to:
 *
 *   See what converter was used when inputting the documents

 *
 *   Override the character set for documents where the specified 
 *   fallback, or auto-detected character set is incorrect
