Thank you very much.

Yes, the code in this post this is a version of the text/binary test
that currently exists in Perl, and it's pretty much what I would have
written ... although I'd probably change the "non-ASCII" test.  As coded
in the example you referred me to, certain normal ASCII text characters
(such as TAB, to name but one) would incorrectly cause a file to be
flagged as binary.

I also would want this test to be performable on a file that's already
open (i.e., an IO object).

I'll wait a day or so to see if someone reports any other currently
written code, but if not, I'll write and post my own version here.
