Interesting. Indeed I thought that a font without any character may be
sufficient. I think EMACS would display rectangles instead.

By the way, if there is a way to create a simple font for my purposes,
without the use of heavy-weight tools like FontForge, I'd be happy to
hear about that! Perhaps it's even possible to directly write the source
code of a Type-1 font and then use the tool "t1asm" [1] to create it.

I am the only person with access to that EMACS - or so it should be. And
the file in question is encrypted.

Storing a one-way hash wouldn't make sense in that case. It's a list of
my passwords, though not all of them: For legal and security reasons,
some are only stored in my brain.
