Apparently grep silently stops processing when it encounters the invalid UTF-8:
The regular expression "." matches a single character, and ".*" matches
a string of characters. In your example, there is an encoding error, and
encoding errors are not characters so "." and ".*" do not match them. I
don't see any bug here.
When the input has invalid characters so grep cannot process it, a message
could be expected
That's a good suggestion, yes.
