It appears that 'rev' is choking on any character \x80 or higher, but
is OK with those \x1f or smaller. It doesn't give an error or ignore
it, it just stops.
I don't have access to a Linux box so I can't see if this happens
there and nothing in the documentation suggests that this is the
correct functionality.
Test case:
printf 'no non-ASCII characters\nhex 01 >\x01< here\nhex 80 >\x80<
here\nLine 4\n'|rev|rev
This is for "rev from util-linux 2.33.1"
I don't have the current version of 'rev' on my system due to not
having updated in a while. I accidentally screwed up my installation
and have been reluctant to wipe it and start over.
So, is this the expected behaviour for the current version of 'rev'
under Cygwin and/or Linux?
The current Cygwin util-linux 2.39.3-2 rev behaves in the same, broken
way. It looks like line-ending char(s) are not being handled correctly.
Don't know yet if it's rev itself or fgetws() being used by rev that's
busted. I'll investigate further. Thanks for the report!
