BINARY FILES

By default, a file that contains a binary zero byte within the
       first 1024 bytes is identified as a binary file, and is processed
       specially. (GNU grep also identifies binary files in this
       manner.) See the --binary-files option for a means of changing
       the way binary files are handled.
