I think you have the essence of a solution, using the Unix filter paradigm at user or
driver level.
Your desire to retain the original file format(s) is very sensible, it is always best to
record "raw" data - for the greatest fidelity.
The ISO 7-layer model provides a paradigm for data transport/storage formats and derived
(presentation) formats.
Good luck with the weather

The first ingredient must be a printer with a a suitable font table, in these times of
soft fonts that should be a given or tractable.
The second element is to convert to and use an MCS / multibyte character representation -
which can differentiate _ ^ and the desired arrow marks.
To do this you could:
- load the file into an editor, save it in MCS format, perform the
necessary substitutions (two global replaces)
- write a program / script to achieve the same effect, read char and convert/translate to
MCS octets.
Note. It is just possible you will find a font with the arrows in the upper 128 glyphs
of 8 bit "ascii", in which case you can skip the MCS conversion.

A filter of some kind is needed.
With the rise of emulators for old machines,I can see text being written with terminal
emulation of the orginal i/o devices, but that leaves printing or tranfering text files a
problem.
JOE could have a REAL - big iron 67, SAM runs windows 2000, TOM has a micro VAX. Every
thing gets dumped to the cloud.
One must keep data as files, none of this crappy mess that this modern 'buy a app'
to print,or read.
How does one share binary and paper tape/cards as files?
Ben.
PS: Back to inventing big iron 67.
