protected  void addCharacterEncoding(int code,
    String name) 
{
        codeToName.put( code, name );
        nameToCode.put( name, code );
}

This will add a character encoding.

 public String getCharacter(int code) throws IOException 
{
        return getCharacter( getName( code ) );
}

This will get the character from the code.

 public static String getCharacter(String name) 
{
        String character = NAME_TO_CHARACTER.get( name );
        if( character == null )
        {
            character = name;
        }
        return character;
}

This will get the character from the name.

 public int getCode(String name) throws IOException 
{
        Integer code = nameToCode.get( name );
        if( code == null )
        {
            throw new IOException( "No character code for character name '" + name + "'" );
        }
        return code.intValue();
}

This will get the character code for the name.

 public String getName(int code) throws IOException 
{
        String name = codeToName.get( code );
        if( name == null )
        {
            //lets be forgiving for now
            name = "space";
            //throw new IOException( getClass().getName() +
            //                       ": No name for character code '" + code + "'" );
        }
        return name;
}

This will take a character code and get the name from the code.

 public String getNameFromCharacter(char c) throws IOException 
{
        String name = CHARACTER_TO_NAME.get( c );
        if( name == null )
        {
            throw new IOException( "No name for character '" + c + "'" );
        }
        return name;
}

This will take a character code and get the name from the code.
