            The SYMBOL field is one of Microsoft's many quirky ways of
            entering text. The string that results from this method looks like
            this:
                SYMBOL 97 \\f "Symbol" \\s 12
            The first word merely tells us that we have encountered a SYMBOL
            field.
            The next value is the Microsoft decimal value. Change this to
            hexidecimal.
            The pattern '\\f "some font' tells us the font.
            The pattern '\\s some size'  tells us the font size.

            string, and make this string the last item in a list. The first
            item in the list is the simple word 'symbol', which tells me that
