If these are Word Processing documents, those codes are
probably special formatting codes, and not actually used
as defined in any chart. They would have been defined by
the specific Word Processing program used.

Many WP file formats use these "out-of-band" control
characters that did not have any printable form for this
purpose. WordPerfect, WordStar, DecWord, etc. all do this.
