Unfortunately, I don't know how to get that binmode() into the
one-liner's angle brackets :-(

Yes, I think that should give the OP the result he was seeking.
Heh ... I didn't realize (until after I had posted) that this was a bash
shell solution.
Yes, the intent was only to draw attention to the PERLIO environment
variable as a possible alternative to binmode, not to offer a complete
solution.
OTOH this was actually run on windows using Strawberry perl from a
cygwin bash shell. That has been my standard setup on windows for more
years than I care to count. Given that you can setup a decent portable
environment including cygwin, ntemacs (with cygwin bash as shell and
tramp via putty for remote anything), strawberry perl(s), and your own
minicpan/darkpan, all on a USB key, that works on any windows from 2000
to win10, I have seen no need to come close to CMD for quite some time :-)
BTW, the :crlf layer is hopelessly broken on windows (can't seek
reliably) so be sure to binmode any file you need to navigate with
anything other than the angle brackets.
The PERLIO variable has also been a lifesaver on some instance where
CPAN heroes, saintly as they are, could not find it in their heart to
test their modules updates on a windows box. If you ever tried to e.g.
install dzil in its early days you will know :-) In such cases it
actually makes sense to setup a whole environment with a nonstandard
setting of PERLIO. YMMV.
Hmmm. I should probably note that because of compatibility issues
between cygwin and ntemacs (if you want to run the cygwin bash as your
emacs shell), I run a very old version of cygwin, probably older than
2009 (its perl at the time was 5.10 I believe). Its bash and make are
sufficient for my need, and I have no trouble using various instances of
strawberry perl with it. No doubt others will have different standards
so take the above with a pinch of salt.
