Is there a glyph that can be used in a similar manner to nf-ple-lower_left_triangle (etc), but is a curve rather than a triangle?

I've been searching for a set of four characters that I can use to draw filled quarter-circles (or quarter-ellipses). There are plenty of triangles and half-circles, but I couldn't find any quarter-circles.

If there isn't one, what would be the best place to start creating one to add?

These really quarter cicles, but rounded corners?

But these are outlines and can not be used to draw filled quarter things.

Then there is the set of quarter blocks, which are there in any combination.

(They look distorted here, but are really 1/4 chunks of the 'cell'.)

what would be the best place to start creating one to add?

I would just fire up Glyphs Inkscape and draw them, from 3 points.

Yeah, I can create the actual glyphs (and patch the font locally).

I more meant, if I wanted to contribute the new glyphs, where's the best place to do that? Directly here, or in one of the icon libraries NF pulls from?

I presume the best place would be https://github.com/ryanoasis/powerline-extra-symbols but I'm not sure.
