Your example which produces the "Binary file" message, produces this:-

address@hidden build (master)]$ LC_ALL=en_GB.utf8 grep y <<<$'x\xa0\xa0y'
x��y

So I am not seeing the message. I looked for any aliases and found:-

alias grep='grep --color'

So I unaliased it and ran again, with same result, except the "y" was not 
coloured.

I don't know why I don't see the message!
