/**
 * The nsIDocCharset interface allows the user to view, 
 * hint, and set which converter is used to read the document's 
 * data.
 *
 * <P>Inside Mozilla all text is encoded as Unicode. By standardizing  
 * on Unicode every piece of code that handles characters no longer 
 * needs to: 
 *
 *     Have access to a character encoding parameter.
 *     Ask is the data stateful?
 *     Ask is the data single byte?
 *     Ask is the data multi-byte?
 *     If multi-byte: have access to a routine that can
 *         determine how many bytes in the current character.
 *
 * 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
 *   data.
 *
 *   Override the character set for documents where the specified 
 *   fallback, or auto-detected character set is incorrect
 *
