Using cygwin I've a problem in less: I can't see colors (for example using grep --color) and I can't set the locale I'm using (LC_ALL=C).
I type this command:
echo òùàòùàòà | grep --color àò | sort | less -R
and the result is:
EDIT: This work:
ls --color=yes | less -R
less --version -> 444
solved the problem of colors using the option
--color=always, but not solved the problem of locale.
