You are a bit confused.  ^L is not `line feed', but a different
character (with ASCII code 12 instead of 10).  It is commonly
represented by the C-like escape sequence "\f" in strings...

To see more information about the ^L character, type in a scratch buffer
the following:

    C-q C-l

Then move the point to that character and type `C-u C-x =' :)
