I agree that it doesn't have to be a real/specific font.
In the beginning, the idea was to be able to insert the logo without relying on a "premade" image.
But as we can see, using the chosen pilcrow as a letter inside a word doesn't feel well.
Moreover, as it is a manually reversed pilcrow, it can't be easily added to all formats.
In my opinion, designing a "pictural" logo would let us more room to make a good one, and would better fit the use cases (like the one showcased by @allefeld).
From this idea, I made a variant of the Vollkorn pilcrow taking some ideas from the whole conversation.
John seems to like to see the "pi" letter as well as a "D", and most of us agree on using something looking like a "P".
So I separated the bowl from the vertical lines bringing some advantages:
* The "pi" and the "D" are more visible (I can still do more works on the upper junction to make the "pi" more evident -- adding some curve similar to the left one, making some offset overlap to highlight the separation, etc.)
* We keep a "P" shape related to the first letter of "Pandoc"
* It is not a "simple" pilcrow anymore, so decrease the risk of confusion from the users.
Using a box around is a good idea making it stands as "I am a logo".
However, a simple square or diamond doesn't bring much meaning.
I used an ISO A4 page symbol which was often used in the previous logo propositions.
One more time, some more work can be done here, like using a letter-sized page (which would make it more squarish).
What do you think about this compromised: starting from a well-designed pilcrow and customizing it to make it looks like a logo.
Kind.
