A new display typeface.
(I know that antialias exists, but I'm in love
with black & white)
I've got problems with this Lc "f", so if
you can help me with your precious consultings...

John; I am not sure if you are right. the § is not to be replaced. They talked about replacing the currency symbol. But they changed that since then. The § is used for example in law books.
The currency Symbol and the Euro sign should now be both in a typeface. The euro has become an xtra unicode number ($20AC) and it is an xtra glyph.

The §ection §ymbol is used to refer to §ections. It often accompanies the ¶ilcrow, which is used to signify ¶aragraphs. Often used in reference to legal documents and some other scholarly works. Please don't replace it.
The character you're thinking of, John, is the generic currency symbol (dec 219), placed at shift-option-2 on the Mac keyboard. That's where you'll find the euro in many updated fonts; however, this placement is sometimes debated by those who feel there is a reason to keep the currency symbol. (You can find a discussion of this over on the ATypI list a couple months back.)

oooh Hrant. You tease my mind. I am not sure as
to 'which letter', but it's history must have something
to do also with rubrication.
Rough definition of rubrication: the adding of the red
ink in manuscripts (also used during the incunable
period) to sections. Used to signify new paragraphs.
Although I don't think they had this term that early.
Kent:
Not a caesura (which seems to be a mid-sentence thingie), but you got the letter correct, so here's your free paragraph:
According to Parkes's "Pause and Effect: An Introduction to the History of Punctuation in the West" (which it seems you returned to the library a bit too early :-), the pilcrow is a symbol for "paraph" (which can also be marked by a double-slash, or a full-height cent-like sign), and it started as a "C", for capitulum.
Complimentary Extra Bonus Sentence:
BTW, Parkes also says that the pilcrow replaced the "paragraphus" (which was marked in various ways, including a section symbol).
Tiffany:
Parkes also writes: "Scribes used the [double-slash] as a direction to the rubricator, but it was often left to fulfil the function of the paraph itself."

Wow, Greg - great stuff!
The only "error" of sorts that I might point out is that the eszet in your serif face shouldn't have a top serif. (But I think the unconventional serif on the pilcrow is great.)
BTW, I think you should make your "at" signs monocameral inside - this form is too much "an 'a' with a circle around it", as opposed to an "at" sign.

Somehow, I'm thinking the name should start with a "B"...
And since this is a display face with a loud and clear voice, maybe "Bugle"?

A nice name, Marc, but there's already this prim Clarendon schoolmarm.
