I suggest to use font-at to get the font-object you need for
font-get-glyphs.

No, that's not possible, sorry.

So the character is actually visible, it is just displayed as a thin
space.  Which means that either its glyph in the font is like that, or
that the font lacks a glyph for it.  What does "C-u C-x =" say when
the cursor is on that thin 1-pixel space?
