d with two ascenders

[jsbien]

Just today I discovered https://collation.folger.edu/2021/09/brevigraphs/. In section 14 you will find examples of "d with two ascenders" (more examples in section 29, one seems identical to Junicode U+F0005, cf. https://groups.google.com/d/msgid/mufi-fonts). I've seen them before quite often in some low quality Polish books and misinterpreted (?) it as an insular d with a dot above. What is the right way to encode it in Unicode/Junicode (possibly with some tags)?

I'm pretty sure that MUFI U+F159 is supposed to stand for this, though the MUFI reference glyph doesn't look a whole lot like the one on the Folger page. If you've got some images handy of this character in manuscripts or early printed books, could you share them here?

I guess you are right. As for examples, cf. fig 21 on p. 9 in http://www.cobrpp.com.pl/actapoligraphica/uploads/pdf/AP2021_Bien.pdf and fig. 33 on p. 33 in http://kwartjez.amu.edu.pl/teksty/teksty2021_1_30/Bien.pdf. I will prepare more images soon.

More examples of the letter d (some with ligatures, sometimes just strange) from two other printers:

Thanks for these. I'm thinking, based on these and entries in Capelli, that one of these shapes would be better for U+F159 than the current one:

Another possibly related character is MUFI U+EBB2, d rotunda with acute, which may be trying to render the shapes where the flourish stroke does not cross. I wonder if it's better interpreted as d with stroke than d with accent:

Opinions?

As for U+F159, I suspect there is some rationale behind the current shape of the glyph, so it looks better to make the additional shapes just the variants. It's a pity MUFI is actually missing the documentation analogical to the Unicode character proposals. Perhaps there is a corpus of MUFI encoded texts for which the scans are easily available and searching in it seems to be the only way to document the reasons for introducing a character.
As for U+EBB2, it looks nice. The terminology doesn't really matter here, but is this a stroke or a comma?
