Handling binary format of an old word processor

[Trevor Jenkins <bslwannabe-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

I have a group of files created long ago with a word processor for the BBC Micro. The word processor(WordWide/WordWisePlus), which originated in the late 1980s, saved documents in a sort of binary format in that some 7-bit printable characters have the eighth bit set to indicate that the character was preceded on screen by a carriage return. Other old ASCII control codes such as SI and SO were used for italics (I think). There are also encapsulated Epson dot-matrix setup sequences at the start of the files. Had a few read throughs of the Pandoc/Lua filter documentation but simply cannot get my head around how these documents could be processed using a Lua filter for pandoc to convert what is essentially a stream of 8-bit bytes into a form that can be used to convert to a modern format.

Would appreciate some pointers to how to handle this task using pandoc and Lua? Otherwise I will have write some one-off throw away C code that does not help me in using Lua for future tasks.

Regards, Trevor.
