That seems unlikely.  grep thinks files are binary if they contain ASCII
NUL, or have a byte sequence that's invalid for the locale, and it only
emits that `Binary file ... matches' if such a line matches the regexp.

Does your grep behave like this?  I used a UTF-8 terminal.

    $ od -tx1z <<<$'x\xa0\xa0y'
    0000000 78 a0 a0 79 0a                                   >x..y.<
    0000005
    $ LC_ALL=en_GB.utf8 grep z <<<$'x\xa0\xa0y'
    $ LC_ALL=en_GB.utf8 grep z <<<$'x\xa0\xa0y\nz'
    z
    $ LC_ALL=en_GB.utf8 grep y <<<$'x\xa0\xa0y'
    Binary file (standard input) matches
    $ LC_ALL=en_GB.iso88591 grep y <<<$'x\xa0\xa0y'
    x��y
    $ LC_ALL=C grep y <<<$'x\xa0\xa0y'
    x��y
    $
