If I don't know the Unicode name and the above input sequence of it,
to be more specifically, I only know its representation in Emacs is
^L, then how to search/match/find/filter out it with regexp.
As a similar example, I can grep it with the following
$ grep $'\014' 11.txt | cat -te
^L$
$ grep $'\f' 11.txt | cat -te
^L$
