The main contents of a FORM FTXT is in its character stream "CHRS" chunks.
Formatting property chunks may also appear.  The only formatting property
yet defined is "FONS", a font specifier.  A FORM FTXT with no CHRS
represents an empty text stream.  A FORM FTXT may contain nested IFF
FORMs, LISTs, or CAT s, although a "stripping" reader (see section 3) will
ignore them.
