Unlike Word files, there is no chance of a Macro Virus in them. I sent our family lawyer some documents converted to Text by request.
Comically the use of curl | bash managed to shoehorn them in there, and there were the occasional terminal escape characters that could do funny and sometimes mischievous things.
There used to be something of a game of making specific files that would change screen colors or play songs off terminal bells, etc, tailored for specific terminals or command prompt windows. I remember a few short animated sequences using various backspaces and colors that only really worked if you could expect the text to be loaded at specific baud rates or in specific BBS software.
