My typical experience is that when people distinguish "text" vs
"binary" files, they mean the whole file can reasonably be made sense
of in a text editor (that's not a precise definition, of course, but I
think it serves the purpose). When I open an SQLite database I have
handy with emacs, it is rife with nulls and other non-printing
characters. Similarly, when I try to run 'less' on it, the response
is
babs:506$ less house.db
"house.db" may be a binary file. See it anyway?
Arguably, as people typically use the distinction, it's not a text
file. Yes, I can extract the text fields as human-readable ASCII,
but that does not make it a text file.

And what just about anybody else would mean by a text file, as well.

My impression (I'd have to go back and recheck) is that it
disqualified it for the OP, as well.
