I'm trying to include a certain unicode character in some files. The 
character is U+2F75 - KANGXI RADICAL BAMBOO: ⽵.

Even though my Windows system has fonts that render that glyph, Emacs
will not use them, and it renders the character as the box with the
"2F75" in it. If if my default face doesn't have the glyph,
shouldn't Emacs fall back on a font that does have the glyph, when it
hits that unicode character? Someone suggested I need a _monospace_ font
that has the glyph, but I have that as well. I downloaded this font for
example:

https://fonts.google.com/specimen/LXGW+WenKai+Mono+TC/glyphs?preview.text=Bambu%20radical:%20%E2%BD%B5&classification=Monospace

Windows "character map" app shows that it has the 2F75 character. But 
Emacs does not use it and renders the box instead. Is this a bug?

When I run `describe-char` on a normal character in my files, I see
this, among other lines. So this is my default face normally. It does
not have the glyph.

         display: by this font (glyph code):
 
harfbuzz:-outline-Consolas-regular-normal-normal-mono-27-*-*-*-c-*-iso8859-1 
(#x05)

That character displays fine on macOS, FWIW.

The font is displayed as:
mac-ct:-*-Baoli SC-regular-normal-normal-*-17-*-*-*-p-0-iso10646-1 (#x3ED3)
