Confirmed. This isn't exactly about binary files, but rather grep stumbles over Cygwin/Newlib's UTF-16 surrogate pair handling here. To trigger this problem, three circumstances must conincide: - you have to use a UTF-8 locale like en_US.UTF-8, - you have to use grep's -i option, - and you have to hit a file with a UTF-8 sequence which translates to a surrogate. I'm looking into a patch to handle this uncommon situation and try to send it upstream.
