Hello,
I found someone who asked the same question on “Stack Overflow”, still unanswered, but this person did not ask it on the mailing list.
Here are the details of the question which are nearly similar to my case: https://stackoverflow.com/questions/50295772/can-grep-search-for-a-line-feed-and-a-null-character-at-the-same-time Thank you for your understanding. Best regards.
