Some installed fonts are not loading

Windows build:
Microsoft Windows [Version 10.0.16299.665]

What I'm trying to do:
Install a font to windows and load it into the default terminal emulator for WSL ubuntu.

What's wrong:
Not all installed fonts are available. As one example, I have installed GNU unifont as shown here:

But I am unable to locate this font in the settings pane of the default terminal.

On the other hand, other terminal emulators have no problem locating all of my fonts. Here's the font selected ConEmu's settings pane:

This is not the only font I've had issues with. For some reason, fonts like Ubuntu Mono show up just fine. But fonts like GNU Unifont or Everson Mono will not show up. Is there some hidden feature of these fonts which makes them incompatible for WSL ubuntu's default terminal? Or is this perhaps a defect? Any help with getting these fonts added would be greatly appreciated. Thank you.

As a side note: I'd also appreciate if anyone could educate me on what is the proper name for "WSL ubuntu's default terminal."

Start by reproducing the missing-font behavior in the Windows Terminal settings pane with GNU Unifont and Everson Mono, then compare it with Ubuntu Mono and ConEmu, which can locate the fonts. Done means installed fonts that are currently absent appear as selectable terminal fonts.
