Oh, I see.  That's what I regularly had to do on files produced
by Windows editors :)  Some time ago Emacs used to display BOMs,
so it was easy to see and delete BOMs, but now doesn't anymore,
since now the default coding system of files with the BOM is
`utf-8-with-signature'.  Forcing it to use `utf-8' with e.g.
`C-x RET c utf-8 RET C-x C-f' is a way to display BOMs
in an UTF-8 file.

When I added a few find-file related functions to ffap,
I don't remember why I missed `find-file-literally'.
Maybe because it has no keybinding (should we try to find one?).
So we definitely need such a function.

However, I wonder why you don't implement it using `ffap-file-finder'
and `call-interactively', like e.g. `ffap-alternate-file' does?
Like other ffap functions, it asks for a filename in the minibuffer,
and allows to get the default behavior with C-u.
