Is that expected behavior, no binary file warning and no matching with
utf-8 locale, even with -a?
It's allowed behavior, as '.' need not match encoding errors.[1] Also,
'grep' need not diagnose encoding errors that don't harm the output.[2]
As you mentioned in your email, using LC_ALL=C should let '.' match any
byte, so that should let you do what you want.
